Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional testing apparatus are used, then testing can be performed, but the testing apparatus cannot accurately replicate user load-bearing motions or simulate accurate usage patterns for softer armrests
Solution Approach 1:
The testing apparatus changes parameters by applying forces in multiple directions (first direction perpendicular to surface, second direction parallel to surface) to simulate realistic user interactions. The system adjusts force magnitude, direction, and application points to accurately replicate load-bearing motions on softer materials like polyurethane armrests
Solution Approach 2:
The invention transitions from conventional single-direction testing to multi-dimensional force application. The apparatus applies forces both perpendicular to the armrest surface and parallel to the surface, creating a two-dimensional force vector system that accurately simulates human elbow interactions and usage patterns
2Reliability
If conventional testing methods are used, then basic testing can be conducted, but the testing cannot effectively benchmark and improve removable furniture parts
Solution Approach 1:
The testing apparatus incorporates a programmable logic controller that monitors and records force application data, enabling quantitative analysis of armrest performance. The system provides feedback through recorded data that can be analyzed to benchmark performance and identify areas for improvement in removable furniture parts
Solution Approach 2:
The testing apparatus is designed with universal applicability through its multi-directional force application capability. The same apparatus can test various types of removable furniture parts (armrests, cushions, etc.) made from different materials, making it a versatile benchmarking tool for the furniture industry
