Window Drop Test Apparatus with Adjustable Guide and Weight
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window drop test apparatuses fail to accurately simulate the impact conditions under which portable device windows, such as those in mobile phones, are subjected when dropped, particularly in terms of applying impact to predetermined positions and replicating real-world fall scenarios with varying angles and weights.
Innovation Solution
A window drop test apparatus featuring a support structure with a guide portion that defines a drop space, allowing for adjustable drop heights and angles, and incorporating a weight attachment to simulate actual device weight, enabling precise testing of impact characteristics across different alignment states and surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a window is tested without additional weight, then the test setup is simple, but it does not replicate real-world drop conditions where the window carries device weight
Solution Approach 1:
The weight portion is nested inside the rear groove of the window structure, creating a compact integrated assembly that simulates the actual device weight without requiring external suspension or complex mounting mechanisms
Solution Approach 2:
The test apparatus creates a simplified copy of real-world drop conditions by using a weight portion that replicates the mass characteristics of an actual portable device, allowing realistic impact testing without requiring the complete device structure
2Adaptability or versatility
If the drop space is fixed, then the apparatus structure is simple, but it cannot test windows at various alignment states and positions
Solution Approach 1:
The guide portion incorporates movable side portions that can be adjusted along grooves or rails, allowing the drop space dimensions and configuration to be dynamically changed to accommodate different window sizes, shapes, and testing requirements
Solution Approach 2:
The guide portion is divided into movable segments (side portions) that can be independently adjusted, allowing flexible configuration of the drop space without requiring complete restructuring of the entire apparatus
3Measurement precision
If impact is applied without precise positioning, then the testing process is quick, but it cannot accurately assess impact characteristics at predetermined positions
Solution Approach 1:
The alignment table and angle provider are used to pre-position the window structure at specific orientations and angles before the drop, ensuring that the impact occurs at predetermined positions without requiring complex real-time adjustment mechanisms during the test
