Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If uniform output intensity is applied across the entire scalp, then the device structure is simple and easy to operate, but the treatment effectiveness is reduced due to non-uniform scalp conditions
Solution Approach 1:
The brush head is divided into multiple independent bristle groups, where each group can be controlled separately. Different bristle groups apply different output intensities according to the local scalp conditions detected by sensors, allowing tailored treatment for damaged areas versus healthy areas without complicating the overall device operation
Solution Approach 2:
The device transitions from static uniform output to dynamic adaptive output. The controller continuously adjusts the output intensity of each bristle group based on real-time sensor feedback about scalp conditions, enabling the system to adapt to varying scalp states while maintaining simple user operation
2Reliability
If high output intensity is used to treat damaged scalp areas, then treatment effectiveness is improved, but unnecessary damage may occur in undamaged areas
Solution Approach 1:
Different bristle groups are assigned different output intensities based on local scalp assessment. Sensors detect scalp conditions in specific regions and the controller applies high intensity only to damaged areas identified by the sensors, while maintaining low or zero intensity in healthy areas, thus eliminating the harm of uniform high-intensity application
Solution Approach 2:
The device incorporates sensors that continuously monitor scalp conditions and provide feedback to the controller. This feedback mechanism enables real-time adjustment of output intensity to match actual scalp needs, preventing over-treatment of healthy areas while ensuring adequate treatment of damaged areas
3Object-affected harmful factors
If low output intensity is used to avoid damaging undamaged scalp, then scalp safety is maintained, but treatment effectiveness is reduced in damaged areas
Solution Approach 1:
The brush head comprises multiple independently controllable bristle groups that can operate at different intensity levels simultaneously. This allows the device to apply low intensity to protect healthy scalp regions while applying high intensity to treated damaged regions, resolving the trade-off between safety and effectiveness
Solution Approach 2:
The brush head is segmented into multiple functional zones with independent control. Each segment can be optimized for its specific treatment need, allowing simultaneous operation at different intensity levels across different parts of the scalp, thus achieving both safety and effectiveness
4Adaptability or versatility
If manual output adjustment is required for each user preference, then treatment can be customized, but operation complexity and time consumption increase
Solution Approach 1:
The device performs automatic scalp assessment and intensity optimization without requiring user input. Sensors automatically detect scalp conditions and the controller autonomously determines the optimal treatment parameters for each region, eliminating the need for manual adjustment while providing customized treatment
Solution Approach 2:
Real-time sensor feedback about scalp conditions enables the controller to automatically customize treatment parameters. The system continuously monitors and adjusts output based on detected scalp state, providing adaptive customization without requiring user knowledge or manual intervention

AI summary
A brush includes a brush body, electrodes provided at the tips of brush bristles, a sensor provided on the surface of the brush body on which the brush bristles are provided, and a controller configured to control the motions of the brush bristles on the basis of the detection output signal of the sensor. The sensor detects the conditions of the scalp, and the brush performs electric stimulation by applying a current of a specific frequency, or performs ion introduction/lead-out by applying a weak current, so as to be suitable for the conditions of the scalp of a target portion.
