Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If stacks of components such as screws, steel plates, scrap materials are used to simulate weight, then the cost is reduced and damage potential is minimized, but the testing process becomes time-consuming and the weight distribution accuracy deteriorates
Solution Approach 1:
The counterweight is divided into multiple adjustable blocks that can be individually positioned and secured at different locations along the rail, allowing precise weight distribution adjustment without requiring custom fabrication for each test scenario
Solution Approach 2:
The fixture provides a universal solution by using standardized components (base, rail, counterweight blocks, securing mechanisms) that can be configured for various testing scenarios, eliminating the need to search for different counterweight objects for each test
2Ease of manufacture
If stacks of components are used to simulate weight, then cost is reduced, but the manufacturing precision and weight distribution accuracy deteriorate
Solution Approach 1:
The fixture allows different sections of the counterweight system to have different properties - counterweight blocks can be positioned at specific locations along the rail to precisely control the center of gravity, and securing mechanisms can be placed at optimal positions to ensure stable fixation
Solution Approach 2:
The system transitions from static, fixed counterweight stacks to a dynamic configuration where counterweight blocks can be moved, positioned, and secured at various locations to precisely match the actual center of gravity of the computing device assembly being tested
3Ease of operation
If manual positioning and securing of counterweights is performed, then flexibility is maintained, but the stability and precision of fixation deteriorate
Solution Approach 1:
The fixture incorporates pre-designed securing mechanisms (such as clamps, locks, or fastening devices) that are built into the base and rail structure, providing stable fixation before testing begins and preventing movement during testing
Solution Approach 2:
The system replaces manual, imprecise positioning with a structured mechanical system featuring rails, guided counterweight blocks, and securing mechanisms that provide both flexibility in positioning and reliability in fixation
