Foldable Floorboard Holding Device with Spring and Magnetic Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foldable holding devices for vehicle trunks or luggage compartments have low strength and are cumbersome to assemble, failing to securely maintain a raised container shape, which limits their ability to hold a sufficient amount of luggage or goods.
Innovation Solution
A foldable holding device with a raisable top panel and side panels connected by hinges, supported by spring mechanisms and magnetic or comb tooth engagement systems, which securely maintain the open position and allow easy assembly into a container shape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If flexible material is used for compartment walls to enable folding and storage, then ease of storage is improved, but strength and ability to hold luggage deteriorates
Solution Approach 1:
The holding device is divided into a rigid base panel and separate flexible side panels that can be folded independently. The rigid base provides structural strength while the flexible side panels enable folding and storage, resolving the contradiction between strength and adaptability.
Solution Approach 2:
The holding device combines rigid and flexible materials in a composite structure. The base panel uses rigid material for strength, while side panels use flexible material for foldability. This composite approach allows both strength and folding capability to coexist.
2Adaptability or versatility
If flexible material parts make up compartment walls to enable folding, then ease of storage is improved, but assembly complexity increases due to need for hooks and fastening mechanisms
Solution Approach 1:
The side panels are merged with the base panel through foldable connections that eliminate the need for separate hooks or fastening mechanisms. The flexible material itself serves as both the panel structure and the connection mechanism, reducing assembly complexity while maintaining folding capability.
Solution Approach 2:
The flexible side panels automatically maintain their connection to the base panel through their own material properties and geometric configuration, without requiring external fastening mechanisms. The structure self-assembles and self-maintains, reducing complexity.
3Adaptability or versatility
If conventional foldable holding devices are raised to container shape, then storage functionality is improved, but stability and ability to maintain raised position deteriorates
Solution Approach 1:
Spring mechanisms are installed to provide upward counteracting force that balances the weight of the side panels and maintains the raised container shape. The springs store mechanical energy when compressed during folding and release it to support the raised position, improving stability.
Solution Approach 2:
The holding device transitions from a static folded state to a dynamic raised state using spring mechanisms. The springs provide continuous dynamic support force that adapts to the weight and position of the side panels, maintaining stability in the raised container configuration.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device can be easily raised and securely maintained in a container shape, effectively preventing goods from moving and providing a stable storage solution for vehicles.
Implementation Method 1
each of the side edges of the raisable top panel and each of the pair of side panels is connected by a spring that outwardly moves each of the pair of side panels as the raisable top panel is raised
Implementation Method 2
each of the first holding sub-members is one of a magnet and a magnet-attractable fitting, each of the second holding sub-members is the other of the magnet and the magnet-attractable fitting, and when the foldable holding device is in the open state, the magnet and the magnet-attractable fitting are contacted to each other so as to maintain the open state of the foldable holding device
