Flap Actuation Mechanism With Single-Drive Lock and Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing actuating devices for flaps on vehicles require complex constructions and multiple drive means to implement various functions such as locking, releasing, and operating against resistance, which results in a large design space and high manufacturing costs.
Innovation Solution
The actuating apparatus features a compact design with a single drive means that allows for multiple functions to be executed through a single rotational motion, utilizing a first and second actuating element with specific locking or release geometries that interact to achieve locking and unlocking of the flap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate drive means are provided for each function (locking, releasing, operating against resistance), then the reliability and functionality are improved, but the device complexity and design space increase
Solution Approach 1:
A single drive means is designed to perform multiple functions including locking, releasing, and operating the flap against resistance through different positions and modes of operation. The actuating apparatus integrates these functions into one unified mechanism rather than using separate drive means for each function.
Solution Approach 2:
Multiple drive functions are merged into a single integrated drive means. The locking mechanism, release mechanism, and resistance-overcoming capability are combined into one actuating apparatus that operates through a unified control system.
2Adaptability or versatility
If multiple separate drive means are provided for each function, then the functional versatility is improved, but the occupied design space increases
Solution Approach 1:
One drive means is designed to provide multiple functions (locking, releasing, operating against resistance) to reduce the overall design space required. This multi-functional approach eliminates the need for separate drive mechanisms that would occupy additional space.
Solution Approach 2:
The locking, releasing, and actuation functions are merged into a single compact drive means, significantly reducing the design space occupied compared to having separate drive means for each function.
3Device complexity
If a single drive means is used for multiple functions, then the design space and manufacturing costs are reduced, but the reliability and coordinated execution of functions may be compromised
Solution Approach 1:
The single drive means incorporates dynamic elements including a spring mechanism that provides automatic return and positioning functions. The spring ensures reliable resetting of the actuating elements after operation, maintaining functional reliability while using a simplified construction.
Solution Approach 2:
The actuating apparatus includes self-service features such as automatic locking and releasing mechanisms that operate without requiring additional separate drive means. The spring-biased design automatically returns components to their proper positions, ensuring reliable operation.
