Rotating Pad Unit for Curved Display Durability Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing testing methods for display apparatuses struggle to effectively test the durability of complex-curved areas, as they lack the capability to apply hits uniformly across variously curved surfaces.
Innovation Solution
A testing apparatus comprising a base, a hit unit that can translate in three perpendicular directions, and a pad unit that can rotate around multiple axes, allowing for precise application of hits on complex-curved areas of display apparatuses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hit body is dropped on a display apparatus to test durability, then the durability testing function is provided, but the ability to test complex-curved areas effectively is insufficient
Solution Approach 1:
The pad unit is designed to be rotatable around a vertical axis, allowing dynamic adjustment of the display apparatus orientation. This enables the hit body to be applied to various positions including complex-curved areas by rotating the pad unit to different angular positions, making the testing system adaptable to different surface geometries
Solution Approach 2:
The testing apparatus introduces rotational movement around a vertical axis as an additional degree of freedom. This adds a rotational dimension to the traditional linear dropping mechanism, enabling coverage of complex-curved areas that require angular adjustment beyond simple vertical impact
2Adaptability or versatility
If the pad unit is made rotatable to enable testing of various areas, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The rotatable pad unit serves multiple functions: it can position the display apparatus for testing different areas (flat, curved, complex-curved), adjust orientation for various hit body trajectories, and provide stable support during impact. This multi-functionality reduces the need for multiple separate testing devices or complex reconfiguration mechanisms
