Solution Overview
Problem
Existing hair grooming devices lack the capability to effectively measure and analyze the interaction with hair during grooming events, such as tension, effort, and tangle resistance, which are crucial for understanding hair conditions and improving grooming processes.
Innovation Solution
Integration of sensors like light-dependent resistors, force-sensitive resistors, load cells, and gyroscopes into hair grooming devices to collect data on proximity, pressure, and movement, with a processor to filter and store or transmit this data for analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensors are integrated into the hair grooming device to measure interaction with hair, then measurement capability is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple sensors (proximity sensor, force sensor, accelerometer, gyroscope) into a single hair grooming device, integrating them into the handle assembly. This merging approach enables comprehensive measurement of hair interaction parameters while maintaining a unified device structure, resolving the contradiction by achieving enhanced measurement capability through systematic integration rather than separate devices.
Solution Approach 2:
The hair grooming device is designed with multi-functionality, serving both as a grooming tool and a measurement system. The sensors are integrated into the existing grooming device structure, allowing it to perform its primary grooming function while simultaneously measuring proximity, force, acceleration, and rotational parameters. This universal design resolves the contradiction by making the device serve multiple purposes without requiring entirely separate systems.
2Loss of information
If multiple sensors are integrated to collect comprehensive data, then data quality is improved, but processing complexity increases
Solution Approach 1:
The processor in the hair grooming device performs preliminary filtering and processing of sensor data in real-time during the grooming event. By pre-processing the data from multiple sensors (proximity, force, accelerometer, gyroscope) as it is collected, the system reduces the complexity of subsequent analysis while maintaining high data quality. This preliminary action resolves the contradiction by handling processing complexity at the source rather than requiring complex post-processing systems.
Solution Approach 2:
The processor acts as an intermediary between the multiple sensors and the external computing system. It receives raw data from all sensors, performs initial filtering and validation, and transmits only the processed relevant data externally. This intermediary role reduces the processing burden on external systems while preserving data quality, resolving the contradiction between comprehensive data collection and processing complexity.
3Reliability
If proximity-based filtering is implemented, then measurement reliability is improved, but computational requirements increase
Solution Approach 1:
The system implements partial filtering by using proximity data to selectively filter force measurement data. Instead of processing all sensor data equally, the system applies filtering only when the proximity sensor indicates the brush is near the hair. This partial action approach improves measurement reliability by focusing computational resources on relevant measurements while reducing overall computational requirements compared to processing all data without selective filtering.
