Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a single metal workpiece is processed by milling to manufacture casing, then the casing has good structural strength, but the processing speed is slow and the yield is low
Solution Approach 1:
The casing is divided into multiple components (plate, frame, main shell) that are manufactured separately and then assembled together. This segmentation allows each component to be produced independently using optimized processes, significantly improving overall productivity while maintaining structural integrity through the assembly of these components.
Solution Approach 2:
The invention uses composite construction by assembling different metal components (plate, frame, main shell) into a unified casing structure. This composite approach enables each component to be manufactured using the most suitable process for its specific requirements, achieving both high productivity and structural strength.
2Strength
If a single metal workpiece is processed by milling to manufacture casing, then the casing has good structural strength, but the manufacturing complexity increases due to requiring huge number of processing machines
Solution Approach 1:
By segmenting the casing into separate components (plate, frame, main shell), the manufacturing process is distributed across fewer, more specialized machines. Each component can be produced using dedicated equipment, reducing the total number of processing machines required compared to milling the entire casing from a single workpiece.
Solution Approach 2:
Different components of the casing are manufactured using different processes optimized for their specific local requirements. The plate uses stamping, the frame uses casting or stamping, and the main shell uses die-casting or stamping, allowing each region to be produced with the most appropriate method rather than using a single complex milling process throughout.
3Strength
If a single metal workpiece is processed by milling to manufacture casing, then the casing has good structural strength, but the feasibility of mass production is limited
Solution Approach 1:
Segmenting the casing into standardized components enables each part to be mass-produced using dedicated stamping, casting, or die-casting processes. These processes are inherently more suitable for mass production than milling, as they allow for rapid production cycles and easier automation, while the components are subsequently assembled to form the complete casing.
Solution Approach 2:
The invention changes the manufacturing parameters by transitioning from a subtractive milling process to a combination of formative processes (stamping, casting, die-casting). This parameter change enables mass production by utilizing processes that can rapidly produce multiple identical components with consistent quality, while maintaining the structural strength required for the casing.
