Integrated Actuator and Key Cylinder for Motorcycle Lid Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional motorcycle locking systems require multiple cables to connect actuators and key cylinders, increasing complexity and cost, and may fail due to battery discharge without a reliable backup mechanism for unlocking vehicle components.
Innovation Solution
Integration of an actuator and key cylinder into a single body, connected to vehicle components via a wire cable, allowing for simplified structure and reduced component count, with the key cylinder positioned for external operation and the actuator provided inside the body cover for enhanced flexibility and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If actuators and key cylinders are connected through different cables, then both functions are provided, but the number of cables increases and costs increase
Solution Approach 1:
The patent combines the actuator and key cylinder into a single integrated unit, allowing both the remote control actuator function and the manual key cylinder function to share common mounting space and connection mechanisms, thereby reducing the number of separate cables needed while maintaining both unlocking functions
2Reliability
If multiple cables are used for actuator and key cylinder connections, then both components can operate, but the structure becomes complex and costly
Solution Approach 1:
By integrating the actuator and key cylinder into one unit, the patent reduces manufacturing complexity and cost while maintaining the reliable backup unlocking mechanism. The integrated design allows both electronic actuator operation and manual key operation to function through a unified structure
3Adaptability or versatility
If the actuator is positioned inside the body cover, then flexibility in component placement is improved, but accessibility for operation may be reduced
Solution Approach 1:
The patent segments the integrated unit into distinct functional portions: the actuator is positioned inside the body cover for flexible placement and protection, while the key cylinder extends outward to remain accessible for manual operation. This segmentation allows both interior positioning benefits and exterior accessibility
