Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cutting devices are used to disintegrate SSDs, then data destruction is achieved, but the device weight exceeds 500 lbs and produces excessive noise
Solution Approach 1:
The cutting system is segmented into a rotary cutting blade with multiple edges and a stationary cutting blade, allowing the device to achieve complete data destruction through multiple cutting angles while maintaining a compact, lightweight structure under 500 lbs
Solution Approach 2:
The rotary cutting blade rotates to provide multiple cutting angles dynamically, eliminating the need for heavy, fixed multi-blade configurations while achieving complete SSD disintegration into particles less than 2mm
2Reliability
If conventional cutting devices are used to disintegrate SSDs, then data destruction is achieved, but the operating noise level is too high for working environments
Solution Approach 1:
The dynamic rotation of the cutting blade at controlled speeds provides multiple cutting angles while maintaining lower operational noise levels compared to static heavy-duty cutters, enabling operation in working environments with acceptable decibel levels
Solution Approach 2:
The rotary blade design effectively creates multiple cutting actions through rotation, copying the function of multiple stationary blades while reducing mechanical impact and noise generation
3Manufacturing precision
If multiple moving parts are used to achieve fine particle disintegration, then particle size reduction is improved, but device complexity and weight increase
Solution Approach 1:
The cutting blade is segmented with multiple cutting edges that provide various cutting angles during rotation, achieving fine particle disintegration (less than 2mm) while maintaining a minimal number of moving parts
Solution Approach 2:
The single rotary cutting blade performs multiple cutting functions through its rotation, replacing the need for multiple separate cutting mechanisms and reducing overall device complexity while achieving the required particle size reduction
