Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional latch testing assemblies for vehicle doors require complex mounting and positioning of latch and striker assemblies to apply forces in different directions, making them cumbersome and inefficient for quick testing.
Innovation Solution
A vehicle latch testing assembly that includes a latch assembly fixed to a base, a striker assembly configured to engage the latch assembly, a strain gauge connected to the striker assembly, and an operating member connected to the strain gauge and pivotally connected to the base, allowing for easy application of forces in various directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional latch testing assemblies are used, then forces can be applied in different directions, but the mounting and positioning requirements become complex and cumbersome
Solution Approach 1:
The operating member is designed to perform multiple functions: it can be positioned at different locations around the latch assembly and pivoted in various directions to apply forces from multiple angles. This single multi-functional component replaces what would traditionally require multiple separate testing devices mounted in specific positions, thereby achieving versatility without complexity
Solution Approach 2:
The operating member transitions from a static fixed-position applicator to a dynamic component that can be relocated and reoriented. By allowing the operating member to pivot about different points and change its angular position, the system gains the ability to apply forces in different directions without requiring complex permanent mounting structures
2Reliability
If conventional latch testing assemblies are used, then latch assemblies can be tested, but the testing process becomes time-consuming and inefficient
Solution Approach 1:
The operating member is pre-configured with strain gauge connections and pivotal mounting capabilities, allowing it to be quickly positioned and ready for testing without requiring complex setup procedures. This preliminary preparation of the testing apparatus enables rapid deployment and efficient testing operations
Solution Approach 2:
The invention extracts the force application function from fixed mounting structures and consolidates it into a single portable operating member. This extraction allows the testing device to be moved and repositioned easily, eliminating time-consuming mounting and positioning procedures while maintaining reliable testing capability
