Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the holding device is arranged without an encasing device, then the assembly is simpler and easier to access, but abraded particles and grinding medium can escape into the environment creating safety hazards
Solution Approach 1:
The holding device is nested within the encasing device, with the holding device positioned inside the encasing device's interior space. The encasing device acts as an outer container that surrounds and contains the holding device, creating a nested structure that prevents particle escape while maintaining functional simplicity
2Reliability
If the holding device is fixed by inner wall sections of the encasing device, then safety is improved by containing particles, but assembly and disassembly becomes more difficult
Solution Approach 1:
The encasing device is divided into a first encasing part and a second encasing part that can be separated from each other. The holding device is fixed between these two separable parts through inner wall sections, allowing the encasing device to maintain containment function while enabling easy assembly and disassembly by separating the two parts
3Manufacturing precision
If fluid guiding inserts are used to direct abrasive fluid, then smoothing effectiveness is improved, but the device complexity increases
Solution Approach 1:
The fluid guiding inserts are designed to perform multiple functions: they direct the abrasive fluid onto the workpiece surface for effective smoothing, and simultaneously serves as structural components within the encasing device. This multi-functionality reduces the need for separate fluid directing components, maintaining manufacturing precision while limiting complexity increase
