Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual cell isolation processing is performed by skilled workers, then cell damage can be controlled, but manufacturing capacity is insufficient
Solution Approach 1:
The patent replaces manual mechanical operations with an automated mechanical cutting system consisting of a blade, blade receiver, and driving unit. This automation maintains controlled cutting forces while dramatically increasing processing capacity, resolving the contradiction between manual control quality and automated production volume.
Solution Approach 2:
The patent controls the pressing force parameter to be the minimum magnitude required for cutting, and optimizes cutting speed and position parameters. This parameter optimization ensures gentle tissue processing that protects cell viability while enabling automated high-volume processing.
2Productivity
If automated cell isolation processing is implemented, then manufacturing capacity is improved, but cell damage increases
Solution Approach 1:
The patent applies only the minimum necessary pressing force for cutting, avoiding excessive mechanical stress on cells. This partial action principle enables automated processing while maintaining cell integrity by applying just enough force to achieve cutting without causing damage.
Solution Approach 2:
The automated mechanical system replaces manual operations with precisely controlled blade movements, consistent cutting forces, and standardized processing parameters, achieving both high throughput and cell protection through mechanical precision.
3Ease of manufacture
If cutting processing is performed with high pressing force, then tissue is effectively cut, but cell damage increases
Solution Approach 1:
The patent applies the minimum necessary pressing force for effective cutting rather than high force. This approach achieves sufficient tissue division while minimizing mechanical stress on cells, maintaining both cutting efficiency and cell viability.
Solution Approach 2:
The patent optimizes the pressing force parameter to a specific range that is sufficient for cutting but low enough to protect cells. This parameter optimization resolves the contradiction between cutting effectiveness and cell protection.
4Device complexity
If blade cutting position is fixed, then processing is simple, but tissue division completeness decreases
Solution Approach 1:
The patent employs a dynamic cutting system where the blade position changes during processing. The driving unit moves the blade to multiple positions on the blade receiver, enabling complete tissue division while maintaining relatively simple device architecture through programmed motion sequences.
