Product

Flexilock likes to present our unique foldable locker design.

This design enables us to transport up to 7020 lockers per truck. And the best part is, we will install the lockers at your festival FOR FREE.

Usability

Having versatile storage space, multiple users can access their lockers simultaneously, eliminating the need to wait in line or take turns at the cash register. Enjoy quick and convenient access to personal belongings at any time!

The lockers are very easy to use and even come with pictures indicating what you need to do if you don’t know!

All lockers are uniquely numbered, enabling users to quickly locate their assigned locker.

Locker doors automatically remain wide open when not in use, facilitating easy identification of available lockers, saving time and effort.

Safety

Belongings won’t get damaged or smudged!

To prevent mold, small ventilation gaps will be provided.

The locker can fit multiple items, and can be accessed very quickly with the help of a key.

Location

The lockers are resistant to water, dust and the sun and are held up by poles to keep the lockers from falling down or sideways.

Transport

7020 lockers fit in 1 truck (2,95m x 2,55m x 8,10m). This is 4x more than the amount of non-foldable lockers which fit in a truck.

For the renter

The lockers can be set up very easily leaving almost no damage to the location.

The product is only available for rent.

The fee for use is €2,- which is very cheap compared to the competitors in this market.

Paying for the lockers can be easily accomplished by only needing to drop 1 coin in the door of the locker.

Maintenance

In order to make sure the locker systems are always functioning and able to be rented, maintenance is needed. Different parts of the system require different types of maintenance, different maintenance actions and will be in need of maintenance at different times. Because of this, the locker system was divided into three different categories that can be grouped together for maintenance. The different groups are the locker panels, the hinges and the locks. Below, their maintenance needs will be explained.

Locker panels

One of the system’s main parts that will need maintenance is the panels of the lockers. These panels might get damaged during transport or use and the panels on the outside will also be exposed to the elements.  The main types of damage to these parts will include scratches, dents and rust. To maintain the panels, a combination of two types of maintenance will be used: reactive maintenance and preventive maintenance.

For possible dents in the panels, reactive maintenance will be used. These panels will be repaired or replaced after damage has been sustained. The damaged panels are to be removed from the system by unscrewing them from the surrounding hinges. It can then be assessed whether the panel can still be repaired or is in need of replacement. The fixed or new panel will then be put back by screwing it to the surrounding hinges.

To limit the impact of scratches and to prevent rust, preventive maintenance will be used. The upkeep of these panels will be scheduled regularly, depending on the expected amount of time and before damage occurs. The maintenance will consist of re-painting the panels, such that there is a protective layer against possible rust. Additionally, repainting will remove any scratches, meaning that the panels will keep looking good.

Hinges

The hinges that allow for the folding of the lockers will require maintenance as well. Due to frequent use, these hinges might become stiff and start to wear. Preventive maintenance will be used to make sure the hinges will continue to function properly. The maintenance for the hinges will be scheduled regularly and will consist of cleaning and lubricating the hinges. Additionally, the hinges will be replaced when the wear has become too much.

Locks

Finally, the locks need to be maintained, since they can break or malfunction through repetitive use. To maintain the locks, reactive maintenance will be used. After an event, it will be checked if all locks are still functioning. If this is not the case, the broken locks will be prepared or replaced.

Design for maintenance

To positively influence future maintenance activities, different design guidelines were incorporated into the design. These design guidelines are split up into three categories: design for reliability, design for maintainability and design for supportability [1]. The incorporated design guidelines and how they were implemented will be explained below:

Design for reliability

Reliability is the ability of an item to perform a required function, under given environmental and operational conditions and for a stated period of time. In order to increase the reliability of the design, the following design guidelines were applied:

R7: Choose materials that can withstand environmental influences

Since the locker systems will mainly be used at outdoor events, they should be able to withstand environmental influences, like sunlight, wind and possibly rain. Because of this, the panels of the lockers are made of steel, which is very durable and inexpensive to maintain.

R9: Use components and materials with verified reliability to minimize the chance of unexpected system behaviour

Besides being durable, the steel panels are also very sturdy, meaning that the chance of them breaking unexpectedly is very low. Additionally, the panels are connected by high-quality hinges. Since it can be predicted how often hinges need maintenance or replacement, there is a low chance of them breaking unexpectedly.

R10: Design robust interfaces between components because their interaction has a strong influence on the reliability of the system

The panels of the locker system are all connected by hinges. Since the system, as well as the folding mechanism, are dependent on these hinges, they should be very robust. Because of this, high-quality hinges will be used.

Design for maintainability

Maintainability is the probability that a system is retained or restored to a specific condition when maintenance is performed by qualified personnel using specific procedures and resources. In order to increase the maintainability of the design, the following design guidelines were applied:

M2: Use standard, universal applicable components

The maintenance procedure can be sped up by using standard, universal applicable components, since they are often easy to maintain and technicians know how to maintain them. In the design, only standard components like hinges, locker locks and steel panels are used.

M7: Components that are regularly replaced need to be easy to handle

The main components that will need regular replacement are probably the hinges. In the system, standard hinges are used that are lightweight, have no sharp edges and are easy to transport.

M11: Design the weakest link to ease the replacement

The weakest link of the design is, as already mentioned, the hinges that connect the panels. If they break or malfunction, there will be no major consequences for surrounding components. Additionally, the hinges are cheap and easily replaceable.

Design for supportability

Supportability is the characteristic of an asset to influence the easiness with which logistic resources can be available at the right time at the right place. In order to increase the supportability of the design, the following design guidelines were applied:

S3: Minimize the number of different types of fasteners

The main type of fastener that is needed are those that connect the hinges to the panels. For all of these connections, the same type of fastener can be used. This means that less different types of spares are needed and that less different types of tooling is needed.

S6: Design for the use of standard tools

The fasteners that were previously mentioned will be standard fasteners. This means that maintenance can be executed using tools in a standardized toolkit that most technicians have.

S8: Design the system in such a way that adequate forecasting of maintenance is possible

Since mainly standard components are used, it is possible to predict the necessary maintenance within certain boundaries. This prevents the unexpected need for maintenance and means that maintenance can be predicted and scheduled.
