Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the hair trimming device uses a predefined cutting position method (WO 572), then the hair cutting precision is improved, but the ease of operation deteriorates due to repeated repositioning requirements
Solution Approach 1:
The patent applies dynamics by transitioning from a static predefined cutting position method to a dynamic system that continuously adjusts cutting length based on real-time position detection. The hair trimming device dynamically modifies cutting parameters according to its detected position on the head, eliminating the need for repeated repositioning while maintaining precision.
Solution Approach 2:
The patent implements feedback through a position detection system that continuously monitors the device's position on the head and feeds this information back to the control system. This feedback loop enables automatic adjustment of cutting length, resolving the contradiction by maintaining precision through continuous position awareness while improving ease of operation through automated control.
2Manufacturing precision
If the hair trimming device requires precise positioning and repositioning (WO 572), then the hair cutting quality is improved, but the loss of time increases due to repeated movements
Solution Approach 1:
The patent applies continuity of useful action by enabling the hair trimming device to operate continuously across the entire head surface without interruption for repositioning. The position detection and automatic adjustment system allows the device to maintain optimal cutting conditions throughout the entire hair trimming process, eliminating time-wasting repeated movements while preserving cutting quality.
3Ease of operation
If the hair trimming device uses automatic position-based adjustment, then the ease of operation is improved, but the device complexity increases due to additional sensors and control systems
Solution Approach 1:
The patent applies universality by designing the position detection system to serve multiple functions: detecting device position, determining orientation, calculating cutting length, and controlling the cutting mechanism. This multi-functional approach improves ease of operation while minimizing the increase in device complexity by making the added components work across multiple operational dimensions.

AI summary
A programmable hair trimming system has a hair trimming device including a receiving element configured to receive an electromagnetic field and at least one source element having an electromagnetic field source. The hair cutting length of the hair trimming device is adjustable, and the at least one source element is external to the hair trimming device and arranged to be placed in a fixed relationship to the head of a person. The hair trimming system is arranged to detect, by an electromagnetic tracking system, the position of the hair trimming device in relation to the at least one source element. Further the hair trimming system relates this position to a previously generated hair length profile data regarding the desired hair trimming length at various positions. Based on the desired hair trimming length at the sensed position, the trimmer cutting length is automatically and dynamically adjusted.
