Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional electrical stimulation device is configured with direct attachment to flexible strap or head cap requiring manual adjustment, then the device can be used by experts, but ordinary persons cannot use it safely due to complex configuration and safety risks
Solution Approach 1:
The device is divided into separate functional modules: a headwear component (flexible strap or head cap), an electrode structure with conductive member, and a control unit. This segmentation allows each component to be optimized independently and simplifies the overall system for ordinary users while maintaining expert-level functionality.
Solution Approach 2:
The patent introduces an intermediary electrode structure that connects the headwear and control unit, featuring a conductive member covered by an insulating member. This intermediary component simplifies the interface between components and ensures safe electrical connection for ordinary users.
2Measurement precision
If the electrode structure is made tiltable and position-adjustable, then accurate brain stimulation can be achieved, but the device structure becomes more complex
Solution Approach 1:
The electrode structure is designed with tiltable and movable characteristics, allowing dynamic adjustment of position and orientation. This dynamic design enables accurate positioning for different brain regions without requiring complex mechanical assemblies, maintaining simplicity while achieving precision.
3Ease of repair
If the patch is made detachable from the electrode structure, then easy replacement is achieved, but connection reliability may be compromised
Solution Approach 1:
The detachable patch is designed as a separate replaceable component from the electrode structure. This segmentation allows the patch to be easily replaced when worn or damaged while maintaining reliable electrical connection through proper interface design between the conductive member and patch.
