Multi-Directional Shock Testing Apparatus with Rotating Drop Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional shock-resistance testing apparatuses are limited to testing impact in one direction, failing to simulate the varied impact directions that electronic devices may experience when falling, which does not adequately assess their overall shock resistance.
Innovation Solution
A shock-resistance testing apparatus featuring a support base with rotating components and a controller that allows the testing board to rotate and lift, enabling the electronic device to be dropped from different angles, simulating multiple impact directions through motor-driven mechanisms and baffle parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional shock-resistance testing apparatus tests only one direction, then the device structure remains simple, but it cannot adequately assess the electronic device's overall shock resistance against multi-directional impacts
Solution Approach 1:
The testing apparatus employs dynamic rotating components including a rotating component that can rotate the testing board to different angles, and a lifting component that can rotate to change the dropping direction. This dynamic capability allows the same apparatus to test multiple directions without requiring multiple fixed testing positions, thereby improving adaptability while controlling structural complexity
Solution Approach 2:
The lifting component serves multiple functions: it can lift the testing board vertically, rotate to change dropping directions, and work in combination with the rotating component to achieve comprehensive multi-directional testing. This multi-functionality allows a single component to replace what would otherwise require multiple separate testing apparatuses
2Reliability
If the testing apparatus adds rotating and lifting components to enable multi-directional testing, then the testing comprehensiveness improves, but the device complexity increases
Solution Approach 1:
The rotating component and lifting component are integrated into a coordinated system where the rotating component rotates the testing board to predetermined angles and the lifting component rotates and lifts to create multi-directional dropping paths. This merging of functions into a coordinated mechanism achieves comprehensive testing while avoiding the need for entirely separate testing systems for each direction
Solution Approach 2:
The rotating component rotates the testing board to predetermined angles before the dropping test, and the lifting component positions the testing board at required heights and orientations in advance. This preliminary positioning ensures that the electronic device receives impacts from specific directions (front, rear, left, right, top, bottom edges) with controlled precision, improving assessment reliability

AI summary
A shock-resistance testing apparatus includes a support base, a first rotating component and a controller provided on the support base. A second rotating component is coupled to one side of the first rotating component. A testing board is placed on the first rotating component. A falling board is placed on the testing board. The controller controls the first rotating component to drive the second rotating component rotating from one side of the testing board to another side of the testing board. The controller controls the second rotating component to lift the testing board. The controller controls the second rotating component to move away from the testing board so that the testing board falls.
