Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an effective system to securely store and manage vehicle doors, particularly in a way that allows for easy removal and reinstallation while minimizing damage and ensuring proper alignment during storage.
Innovation Solution
A door retention system featuring a housing with slots designed to fit vehicle doors, equipped with sensors to detect door presence, rollers for easy insertion, cushions for protection, and a light assembly for guiding users on correct placement, along with retention straps to secure the doors within the system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If vehicle doors are removed and stored externally, then door accessibility is improved, but door security and protection from damage deteriorate
Solution Approach 1:
The door retention system nests vehicle doors within a housing structure that has slots specifically designed to accommodate door dimensions. The doors are stored inside the housing rather than externally, providing security and protection while maintaining easy accessibility through the slot openings.
Solution Approach 2:
The housing structure acts as an intermediary between the door and the external environment. It provides a protected intermediate storage location that secures the door while allowing controlled access, resolving the contradiction between accessibility and protection.
2Ease of operation
If doors are stored in shallow slots, then insertion ease is improved, but door stability and proper positioning deteriorate
Solution Approach 1:
The slot depth is designed to extend sufficiently into the housing to accommodate the full length of the door, creating a three-dimensional constraint that prevents door movement. This deep slot configuration maintains easy front-facing insertion while providing stability through extended lateral and depth-wise constraints.
3Measurement precision
If sensors are added to detect door presence, then door positioning accuracy is improved, but system complexity increases
Solution Approach 1:
Optical or electromagnetic sensors replace complex mechanical detection mechanisms. The sensors can detect door presence through non-contact means, providing precise measurement while adding minimal mechanical complexity to the retention system.
4Object-affected harmful factors
If cushions and rollers are added to the slot, then door protection and insertion ease are improved, but device complexity increases
Solution Approach 1:
Cushions are pre-installed within the slot to provide protective contact surfaces before door insertion occurs. This beforehand cushioning prevents damage during insertion and storage without requiring complex active protection mechanisms.
Solution Approach 2:
Rollers act as intermediary elements between the door and the slot structure, facilitating smooth insertion while distributing contact forces. These simple mechanical intermediaries reduce friction and prevent damage without adding significant complexity.

AI summary
A door retention system includes a housing defining a slot configured to accept the insertion of a door. The slot is deep enough to position a majority of the door within the slot. A sensor is positioned within the slot and configured to detect the presence of the door within the housing.
