Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If user directly selects electrode positions, then ease of operation is improved, but manufacturing precision deteriorates
Solution Approach 1:
A guide structure with guide grooves serves as an intermediary between the user and the electrode placement positions. The guide structure includes a head model with multiple guide grooves that physically guide the user to place electrodes at predetermined positions, thereby ensuring positioning precision while maintaining ease of operation.
Solution Approach 2:
The guide structure creates a physical copy or model of the head with predetermined electrode positions represented by guide grooves. This copy allows the user to easily place electrodes by following the grooves, ensuring accurate reproduction of the intended electrode configuration without requiring the user to manually calculate or measure positions.
2Productivity
If multiple electrode positions are selected, then productivity is improved, but device complexity increases
Solution Approach 1:
The guide structure is segmented into multiple guide grooves, each corresponding to a specific electrode position. This segmentation allows the device to handle multiple electrode placements simultaneously through a single integrated guide structure, improving productivity without proportionally increasing complexity.
Solution Approach 2:
The guide structure serves multiple functions: it provides physical guidance for electrode placement, defines multiple predetermined positions, and ensures proper spacing and configuration. This multi-functionality allows the device to manage multiple electrode positions efficiently without requiring separate components for each function.
