Vehicle Storage Sidewall Hook Recess Interlock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional storage structures for vehicle interiors face issues where the sidewall member can detach inwardly when a force is applied from outside to inside, potentially damaging the storage unit or its contents.
Innovation Solution
A storage structure with a sidewall member featuring an engaging hook that urges against an engaging recess when a load is applied from outside to inside, preventing detachment and allowing easy outward detachment when the load is reversed, utilizing a soft resin material for the sidewall member to enhance flexibility and rigidity with reinforcing portions and a stepped bottom configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sidewall member is made movable to prevent damage when objects are put in or taken out, then the storage unit becomes more protective, but the sidewall member may detach inward when load is applied
Solution Approach 1:
The engaging hook and engaging recess are designed to apply preliminary counter-action forces that prevent the sidewall member from detaching inward when external loads are applied. The hook engages with the recess to create a mechanical interlock that resists inward movement while allowing controlled outward movement.
Solution Approach 2:
The sidewall member is segmented into functional portions: a movable sidewall portion for absorption, an engaging hook for connection, and a reinforcing portion for structural support. This segmentation allows each part to perform its specific function independently while working together as a unified system.
2Strength
If a hard material is used for the wall portion, then the storage unit structure is strong, but it cannot be deformed easily and may cause damage
Solution Approach 1:
The storage unit employs different material properties in different locations: hard rigid materials for the main body structure to provide strength, and soft movable material for the sidewall member to provide deformation capability. This local differentiation of material properties allows the structure to be both strong and adaptable.
Solution Approach 2:
The storage unit combines different material types - rigid resin or similar hard materials for the main body, and soft movable material for the sidewall member. This composite material approach allows the structure to exhibit both the strength of hard materials and the flexibility of soft materials in appropriate locations.
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 solution effectively prevents sidewall member detachment inwardly while allowing easy outward movement and retraction, enhancing the structural integrity and usability of the storage unit, particularly in vehicle doors.
Implementation Method 1
the sidewall member is configured in a manner that the engaging hook is urged against the engaging recess when a load is applied on the sidewall member from an outside to an inside of the storage unit

AI summary
A storage structure for a vehicle interior includes a hollowed storage unit having an opening in the top of the storage unit. The storage unit includes a storage sidewall section surrounding a storage space for an object to be stored. The storage sidewall section includes a sidewall body portion and a sidewall member formed of a member separate from the sidewall body portion. The sidewall member is configured such that an engaging hook provided for the sidewall member is urged against an engaging recess provided for the sidewall body portion when a load is applied on the sidewall member from an outside to an inside of the storage unit.
