Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Many vehicles, particularly mountain bikes and motorcycles, are ridden with improper suspension initial settings, leading to suboptimal handling and comfort due to incorrect sag and damping settings, which affect steering geometry and pedaling efficiency.
Innovation Solution
A system comprising sensors and a processor that measure operational characteristics of vehicle suspension, providing data for adjusting sag, rebound damping, and compression settings to optimize the riding experience through a user interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual suspension adjustment is used, then device complexity is reduced, but measurement precision and adjustment accuracy deteriorate
Solution Approach 1:
The suspension system performs self-measurement and self-adjustment through integrated sensors and processors that automatically detect sag conditions and control damper pre-load, eliminating the need for external measurement tools and manual adjustment procedures
Solution Approach 2:
Traditional mechanical measurement tools and manual adjustment mechanisms are replaced with electronic sensors, processors, and controlled damper systems that provide automated measurement and adjustment functions
2Device complexity
If fixed suspension settings are used, then device complexity is reduced, but adaptability to different riding conditions deteriorates
Solution Approach 1:
The suspension system transitions from fixed mechanical settings to dynamically adjustable parameters through electronic control, allowing real-time modification of damper pre-load and rebound damping based on measured conditions and rider preferences
Solution Approach 2:
The system enables modification of suspension parameters including sag, rebound damping, and compression settings through electronic adjustment of damper pre-load, allowing adaptation to different riding conditions without mechanical reconfiguration
3Measurement precision
If automated sensor-based adjustment is implemented, then measurement precision and adjustment accuracy are improved, but device complexity increases
Solution Approach 1:
The sensor system and processor serve multiple functions including measuring suspension operational characteristics, determining sag conditions, controlling damper pre-load, and providing user feedback, consolidating what could be separate complex subsystems into integrated components
4Adaptability or versatility
If multiple suspension parameters are adjustable, then adaptability to different conditions is improved, but ease of operation deteriorates
Solution Approach 1:
The system automatically performs measurement and adjustment functions without requiring user intervention for complex procedures, while still allowing riders to select preferred riding styles through simple interface options
Solution Approach 2:
The system performs preliminary measurements of suspension operational characteristics and pre-calculates optimal settings before the rider needs to make adjustments, reducing the complexity of the adjustment process

AI summary
Methods and apparatus of a system for vehicles comprising a vehicle suspension, a sensor operable to measure an operational characteristic of the vehicle suspension, and a processor in communication with the sensor that is operable to suggest an operational setting of the vehicle suspension in response to an input from the sensor corresponding to the operational characteristic. A method for adjusting a suspension of a vehicle may comprise receiving suspension data with a processor, calculating a suspension setting suggestion with the processor, communicating the suspension setting suggestion to a user interface device, and adjusting the suspension based on the suspension setting suggestion.
