Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suspension locking devices for vehicles require multiple operators for synchronization, are complex, unreliable, and not adjustable, making them difficult to use and ineffective for different types of suspension-protection assemblies.
Innovation Solution
A vehicle suspension locking system with a telescopic fork suspension and fork protector, featuring a first assembly with a capture hook and a second assembly with a locking finger, utilizing return means to automatically lock and unlock the suspension based on the movement of telescopic tubes, allowing for adjustable locking and unlocking without manual synchronization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If prior suspension locking devices are used, then the suspension can be locked, but multiple operators are required for synchronization
Solution Approach 1:
The locking system uses the rider's own weight and suspension movement to automatically trigger the locking mechanism. When the rider applies downward force on the suspension, the first assembly moves relative to the second assembly, automatically engaging the locking element without requiring any additional operator action.
Solution Approach 2:
The locking element is pre-positioned in the second assembly and automatically projects when the suspension is compressed. The geometry of the first and second assemblies is designed so that the locking action occurs automatically as a result of the suspension's downward movement, eliminating the need for synchronized manual operation.
2Reliability
If prior suspension locking devices are used, then the suspension can be locked, but perfect synchronization between operators is required
Solution Approach 1:
The system uses the suspension's own movement to trigger the locking mechanism. The relative motion between the first assembly (attached to suspension) and second assembly (attached to fork guard) automatically activates the locking element, eliminating the need for external synchronization.
Solution Approach 2:
The locking mechanism is designed to be dynamic rather than static. The locking element projects automatically in response to the suspension's compression, making the locking action dependent on the actual suspension movement rather than requiring precise timing from multiple operators.
3Adaptability or versatility
If prior suspension locking devices are used, then the suspension can be locked, but the devices are not adjustable for different suspension types
Solution Approach 1:
The locking system is designed to adapt to the dynamic characteristics of different suspension types. The first assembly moves with the suspension while the second assembly remains fixed to the fork guard, allowing the mechanism to automatically adjust to different suspension travel and compression characteristics without requiring mechanical reconfiguration.
Solution Approach 2:
The locking mechanism is designed with universal applicability to different suspension types. The relative motion-based triggering mechanism works with various suspension configurations, and the system can be adapted to different fork guard geometries while maintaining the same fundamental locking principle.
4Reliability
If prior suspension locking devices are used, then the suspension can be locked, but the devices are complex with difficult-to-machine parts
Solution Approach 1:
The locking system is divided into two separate assemblies: the first assembly attached to the suspension and the second assembly attached to the fork guard. This segmentation allows each component to be manufactured independently using simpler processes, avoiding the need for complex integrated parts that are difficult to machine.
Solution Approach 2:
The locking mechanism uses simple geometric shapes and forms that can be easily replicated through standard manufacturing processes. The first and second assemblies use basic mechanical forms that are straightforward to machine, avoiding complex geometries that would increase manufacturing difficulty.
