Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual hand-rasping is used to level the EPS layer, then skilled labor can achieve smooth surfaces, but the process is inefficient and prone to variations in flatness and alignment
Solution Approach 1:
The patent replaces manual mechanical hand-rasping with an automated mechanical leveling system featuring a programmable robotic arm equipped with a rasping tool. The robotic arm executes predetermined leveling paths and parameters, eliminating human variability while maintaining high precision flatness and alignment standards. This automation substitution directly resolves the contradiction by achieving both high precision and improved productivity.
Solution Approach 2:
The patent implements programmable control parameters for the robotic leveling system, allowing precise adjustment of rasping depth, speed, and path. These controllable parameters enable consistent reproduction of high-quality surfaces at increased production rates, simultaneously achieving manufacturing precision and productivity improvements that manual methods cannot provide.
2Manufacturing precision
If skilled labor is used for precise hand-rasping, then panel alignment can be achieved, but costs increase and safety concerns arise
Solution Approach 1:
The patent replaces skilled manual labor with an automated robotic leveling system that programmatically achieves precise panel alignment. This substitution eliminates the need for expensive skilled workers while maintaining alignment precision, and removes safety concerns associated with manual handling of sharp tools and heavy panels.
Solution Approach 2:
The robotic system incorporates sensors and feedback mechanisms that allow it to self-adjust and self-correct during the leveling process, achieving precise alignment autonomously without requiring skilled human operators. This self-service capability reduces labor costs and improves safety while maintaining high precision standards.
3Adaptability or versatility
If panels with varying thicknesses are manually aligned, then installation can proceed, but the process becomes complicated and time-consuming
Solution Approach 1:
The robotic leveling system incorporates programmable parameters that automatically adjust to accommodate varying panel thicknesses. The system can be programmed with different thickness profiles and automatically modifies its rasping operations accordingly, eliminating the need for time-consuming manual measurements and adjustments for each panel variation.
Solution Approach 2:
The patent designs the robotic leveling system with universal adaptability to handle panels of various thicknesses through programmable control. The same system can accommodate different panel specifications by loading appropriate parameter sets, making the alignment process efficient and eliminating the need for specialized manual procedures for each thickness variation.
