Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suspension fork assemblies for bicycles lack the ability to provide independent and selectable settings for compression damping, limiting their effectiveness in various riding conditions.
Innovation Solution
A suspension fork assembly with multiple independent flow control elements configured for operation at different settings of compression damping, allowing for lockout, firm, and soft performance, and a system to adjust bypass flow, enabling selectable and independent settings for lockout, firm, and soft suspension performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing suspension fork assemblies use a single flow control element, then the device complexity is reduced, but the adaptability for different riding conditions deteriorates
Solution Approach 1:
The suspension fork assembly is segmented into multiple independent flow control elements (first, second, and third flow control elements) that can be independently adjusted. Each flow control element controls a specific aspect of compression damping, allowing riders to customize the suspension characteristics for different riding conditions such as lockout, firm, and soft performance modes.
Solution Approach 2:
The flow control elements are designed to be dynamically adjustable during operation. The system allows riders to change the compression damping characteristics on-the-fly by adjusting the flow control elements, enabling the suspension to adapt to varying terrain and load conditions without requiring multiple separate suspension systems.
2Adaptability or versatility
If multiple flow control elements are added to provide independent settings, then the adaptability improves, but the device complexity increases
Solution Approach 1:
Multiple flow control elements are integrated into a single suspension fork assembly, allowing one device to perform multiple functions. Each flow control element can be adjusted independently to provide different compression damping characteristics, enabling the same suspension system to handle various riding styles and conditions (lockout, firm, soft) without requiring separate suspension systems.
Solution Approach 2:
The patent combines multiple flow control elements and their adjustment mechanisms into a unified suspension fork assembly. The first, second, and third flow control elements are integrated within the same damper body, sharing common structural components and fluid pathways, which reduces overall system complexity compared to using separate independent suspension systems for each mode.
