Fuel Lid Opener Locking Mechanism for Auto-Manual Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fuel lid openers lack standardization in mounting structures due to differences between push-operation and switch-operated types, leading to complex designs and difficulties in conversion between automatic and manual opening modes.
Innovation Solution
A fuel lid opener with a case-mounted lifter and push lifter mechanism, featuring a locking mechanism with a stopper that can be moved between locking and lock-releasing positions, allowing for easy conversion between automatic and manual opening modes by modifying the stopper's engagement with the push lifter mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different mounting structures are used for push-operation and switch-operated fuel lid openers, then each type can be optimized for its specific function, but the design becomes complex and cannot be standardized
Solution Approach 1:
The push lifter mechanism is designed with a universal mounting structure that can accommodate both push-operation and switch-operated modes. The mechanism includes a lifter arm, cam follower, and spring assembly that function identically in both modes, with the only difference being the trigger method (manual push vs. motor-driven actuator). This universality allows standardization of the mounting structure while maintaining adaptability to different operational modes.
2Ease of operation
If a fuel lid opener is designed for automatic opening with a drive source, then opening convenience is improved, but conversion to manual push operation becomes difficult
Solution Approach 1:
The system employs a dynamic configuration where the actuator (motor or manual push rod) can be selectively engaged or disengaged from the push lifter mechanism. The mounting structure includes coupling elements that allow easy connection and disconnection of the drive source, enabling conversion between automatic and manual modes without permanent structural modifications. The spring-loaded lifter mechanism remains functional in both configurations.

AI summary
A fuel lid opener-has: a heart cam mechanism that is structured so as to, each time a lifter is push-operated via a fuel lid, cause the lifter to alternately repeat advancing-out and withdrawing, and so as to push the fuel lid open due to advancing-out of the lifter; and a locking mechanism-that can restrict operation of the heart cam mechanism. At the locking mechanism, a time when a stopper is moved by operation of a motor, and the aforementioned restricting is released, the aforementioned stopper engages with the heart cam mechanism and operates the heart cam mechanism. Due thereto, the lifter advances-out, and the fuel lid is pushed open.
