Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If charging holes are formed by cutting or drilling through the charging plate, then charging function is achieved, but material is wasted and manufacturing cost increases
Solution Approach 1:
The charging plate is divided into multiple separate charging plate members, each with a specific shape that allows charging holes to be formed by pressing rather than cutting. This segmentation enables the charging function to be achieved while minimizing material waste, as the plates can be formed from continuous material without requiring removal of large portions.
Solution Approach 2:
The charging holes are formed by pressing during the manufacturing process before the charging plate members are assembled into the final device. This preliminary formation of charging holes eliminates the need for subsequent cutting or drilling operations, thereby preventing material waste and reducing manufacturing complexity.
2Reliability
If charging holes are formed by cutting or drilling through the charging plate, then charging function is achieved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The charging plate is segmented into multiple charging plate members that can be manufactured separately using simple pressing operations, then assembled together. This segmentation transforms a complex cutting/drilling process into simpler, more manufacturable steps.
Solution Approach 2:
The mechanical cutting or drilling process is replaced with a pressing operation during manufacturing. This substitution eliminates the complexity associated with cutting tools, tool paths, and precision hole formation, replacing them with a simpler forming process.
3Strength
If remaining regions of the charging plate excluding charging holes are blocked in the dust introduction direction, then structural support is provided, but pressure loss increases
Solution Approach 1:
Instead of blocking the dust introduction direction with solid plate material (one-dimensional obstruction), the design uses the arrangement and spacing of multiple charging plate members to provide structural support while maintaining flow paths. The support function is achieved through the two-dimensional arrangement of plates rather than three-dimensional blocking.
Solution Approach 2:
Different regions of the charging plate structure are assigned different functions: some regions (charging plate members) provide structural support, while other regions (charging holes and interstitial spaces) are optimized for dust flow. This local differentiation allows structural integrity without excessive pressure loss.
4Reliability
If multiple separate dust collection plates are assembled with through bars, then dust collection function is achieved, but assembly complexity increases and productivity decreases
Solution Approach 1:
Multiple dust collection plate members are merged into a single integrated dust collection plate through continuous forming or bonding processes. This merging eliminates the need for separate assembly operations involving through bars and multiple components, thereby increasing productivity while maintaining the dust collection function.
Solution Approach 2:
The dust collection plate is designed as a multi-functional component that simultaneously provides dust collection surfaces, structural support, and electrical connections. This universality reduces the number of separate parts needed, simplifying assembly and increasing productivity.
