Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple different sensor devices are used to measure various hair parameters, then the comprehensiveness of hair condition assessment is improved, but the difficulty of summarizing and evaluating the results increases
Solution Approach 1:
The patent combines multiple sensor devices (optical sensor, NIR sensor, microscope, contact microphone) into an integrated measurement system that collects various hair parameters simultaneously. The data processing device consolidates results from all sensors and provides a unified hair condition assessment, eliminating the need for separate evaluation of multiple independent measurements.
Solution Approach 2:
The patent introduces a data processing device as an intermediary that receives raw data from multiple sensor devices, processes and standardizes the information, and generates a comprehensive hair condition report. This intermediary component simplifies the evaluation process by automatically integrating results from different measurement methods.
2Measurement precision
If multiple sensor devices are integrated into one system, then the measurement comprehensiveness is improved, but the device complexity increases
Solution Approach 1:
The patent designs a multi-functional measurement system where a single device integrates multiple sensor types (optical, NIR, microscopic, acoustic) to perform various hair parameter measurements. This universal device eliminates the need for multiple separate instruments while maintaining comprehensive measurement capabilities.
Solution Approach 2:
The patent merges multiple independent sensor devices into one integrated system. The optical sensor, NIR sensor, microscope, and contact microphone are combined into a single measurement device that can assess various hair parameters simultaneously, reducing system complexity while improving measurement precision.
3Adaptability or versatility
If traditional single-method hair assessment is used, then the device simplicity is maintained, but the ability to provide personalized treatment recommendations is limited
Solution Approach 1:
The patent measures multiple hair parameters (cysteine acid content, fluorescence, surface roughness, acoustic emissions) instead of relying on a single measurement. By changing from single-parameter to multi-parameter assessment, the system enables personalized treatment recommendations based on comprehensive hair condition data.
Solution Approach 2:
The patent replaces traditional subjective or single-method hair assessment with an integrated electronic measurement system using multiple sensors and data processing. This substitution enables objective, precise, and personalized evaluation of hair condition for tailored treatment recommendations.
