Selective retention system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing organizational applications in vehicles fail to securely and selectively retain items, leading to disorganization, damage, or damage to the vehicle during operation.
Innovation Solution
A selective retention system comprising side and end retention rails with attachment and retention portions, featuring teeth and apertures, that securely hold items in place using mechanical fasteners or adhesives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If items are placed on shelves in vehicles, then storage capacity is provided, but items move during operation causing disorganization and damage
Solution Approach 1:
The retention system employs movable retainers that can slide along the retention rails to adjust positioning. The retainers engage with teeth on the rails to secure items at selected positions, then can be released and repositioned to access items. This dynamic adjustment mechanism resolves the contradiction by providing both secure retention during vehicle operation and easy accessibility when needed.
Solution Approach 2:
The retention retainer acts as an intermediary between the item and the retention rail. It provides the securing function through engagement with the teeth on the rail, while its movable nature along the rail allows for easy item access. This intermediary mechanism enables both secure retention and ease of operation without requiring direct permanent attachment.
2Reliability
If dividers or structures are added to compartmentalize items, then item organization is improved, but the structures are insufficient to adequately secure items
Solution Approach 1:
The retention system divides the retention function into separate components: retention rails with teeth mounted on the shelf, and movable retainers that engage with the teeth. This segmentation allows each component to be optimized independently - the rails provide secure engagement points while the retainers provide adjustable securing capability, achieving reliable item security without excessive overall complexity.
Solution Approach 2:
The retention rails feature teeth at specific locations along their length, providing localized engagement points. The retainers engage with these teeth at specific positions to secure items. This local quality approach - having teeth only where needed rather than continuous complex structures - achieves adequate item security while maintaining simplicity of the overall system.
3Reliability
If items are securely retained on shelves, then damage and disorganization are prevented, but removal of items becomes difficult
Solution Approach 1:
The retainers are designed to be dynamically movable along the retention rails. They can be quickly slid to engage with teeth to secure items, and just as quickly slid to disengage for item removal. This dynamic capability prevents item damage during transport while enabling rapid item access, resolving the contradiction between security and removal time.
Solution Approach 2:
The retention system is designed for easy user operation without requiring tools or complex mechanisms. The retainers can be manually engaged and disengaged by the user through simple sliding motion along the rails. This self-service design enables quick item removal while maintaining secure retention during vehicle operation, minimizing time loss.

AI summary
A selective retention system may have at least one side retention rail with an attachment portion and a retention portion. The retention portion may have a plurality of teeth. The system may also have an end retention rail with an attachment portion and a retention portion, where the retention portion at least one aperture.
