Curved Wire Wheel Retention Device for Vehicle Compartment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current spare wheel storage systems in vehicles are inadequate for holding larger used wheels, leading to safety and comfort issues due to the risk of the wheel moving during vehicle movement, especially in the event of impacts or rollovers.
Innovation Solution
A wheel retention device using a curved wire structure that can transition from a lowered position to a raised position to securely hold wheels of varying sizes, including those larger than the spare wheel, with securing means like straps and hinges integrated into the vehicle's structural elements, ensuring the wheel is retained upright and inclined within the trunk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a central fixing means (screw) is used to retain the spare wheel, then the spare wheel is securely held in the trunk, but larger used wheels cannot be stored as they do not fit in the compartment
Solution Approach 1:
The wire structure is designed to be movable and adjustable, transitioning between a lowered position for compact spare wheels and a raised position for larger used wheels. This dynamic configuration allows the same structure to adapt to different wheel sizes and storage requirements, resolving the contradiction between compartment size and wheel size accommodation.
Solution Approach 2:
The invention introduces a vertical dimension to the storage system by allowing the wire structure to move between lowered and raised positions. This enables the compartment to accommodate wheels of different sizes by utilizing vertical space adjustment rather than being constrained by a fixed horizontal footprint.
2Adaptability or versatility
If the wheel is placed free in the trunk, then larger used wheels can be stored, but the wheel may move during vehicle movement causing safety and comfort problems
Solution Approach 1:
The wire structure is pre-configured to contact and restrain the wheel at critical points before movement can occur. The structure's geometry is designed to prevent rolling and shifting motions, providing preliminary restraint that maintains wheel stability during vehicle movement, impacts, or rollovers.
Solution Approach 2:
The wire structure serves as an intermediary element between the wheel and the trunk compartment. It provides a controlled interface that secures the wheel in place while allowing for different wheel sizes, thus maintaining both adaptability and reliability through this mediating structure.
3Reliability
If a fixed wire structure is used to hold the wheel, then the wheel is securely retained, but the structure cannot adapt to different wheel sizes
Solution Approach 1:
The wire structure incorporates movable joints and flexible segments that allow it to dynamically adjust its configuration. This enables the structure to maintain secure retention of the wheel while adapting to different wheel sizes, resolving the contradiction between fixed security and flexible adaptability.
Solution Approach 2:
The structure's geometric parameters (angles, positions, dimensions) can change to accommodate different wheel sizes while maintaining the retention function. The wire structure's configurability allows parameter adjustment without compromising the security of wheel retention.
