Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a single head CNC device is used to process the case, then the device complexity is low, but the processing area is limited to only the upper surface
Solution Approach 1:
The single CNC device is segmented into multiple independent processing heads (first head, second head, third head, fourth head), each capable of processing different surfaces. The first head processes the upper surface, while the second and third heads process side surfaces, thereby expanding the total processing area without requiring multiple separate machines.
Solution Approach 2:
The processing capability transitions from two-dimensional (upper surface only) to three-dimensional by adding heads that can access different spatial dimensions. The second head rotates to access side surfaces, and the third head moves to process patterns on previously processed surfaces, enabling comprehensive multi-surface processing.
2Manufacturing precision
If conventional processing methods (etching, laser, pressing) are used, then the manufacturing process is simple, but the design complexity and refinement are limited
Solution Approach 1:
Traditional mechanical processing methods (etching, laser, pressing) are replaced with CNC-based mechanical processing. The CNC device uses computer-controlled cutting tools to create precise patterns on both upper and side surfaces, achieving higher manufacturing precision and design complexity that cannot be obtained through conventional methods.
3Adaptability or versatility
If only the upper surface is processed, then the processing time is short, but the design versatility is restricted
Solution Approach 1:
The CNC device maintains continuous useful action by coordinating multiple heads that process different surfaces simultaneously or in sequence without idle time. The second head processes side surfaces while the first head completes upper surface processing, and the third head immediately follows to add secondary patterns, ensuring continuous productive operation.
Solution Approach 2:
The processing sequence is carefully planned with preliminary actions: the first head processes the upper surface first, then the second head rotates to process side surfaces, and the third head prepares to process patterns on previously completed surfaces. This preliminary sequencing optimizes the overall processing time while achieving comprehensive design versatility.
