Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mechanical switches are used for controlling hairdressing apparatus, then the device structure is simple, but the ease of operation is poor and user control is limited
Solution Approach 1:
The patent replaces mechanical switches with a touch sensing system that uses capacitive sensing to detect user input. The touch sensing shell with conductive layers and control circuitry eliminates the need for mechanical moving parts, providing a more responsive and durable interface while maintaining structural simplicity through integrated circuit boards.
Solution Approach 2:
The flexible printed circuit board acts as an intermediary between the touch sensing shell and the rigid printed circuit board, allowing the touch interface to be integrated into the housing while maintaining electrical connections to the control system without requiring complex mechanical switch assemblies.
2Productivity
If mechanical switches are used, then the device structure is simple, but the productivity and efficiency in hair styling operations are limited
Solution Approach 1:
The touch sensing system provides faster and more precise control over hairdressing functions compared to mechanical switches. Users can quickly adjust settings and control operations through touch input, improving styling efficiency without adding complex mechanical components.
3Ease of operation
If a touch sensing shell is integrated with flexible and rigid circuit boards, then the ease of operation is enhanced, but the device complexity increases
Solution Approach 1:
The patent merges the touch sensing shell with the circuit board assembly by integrating the flexible printed circuit board directly onto the rigid printed circuit board and mounting the touch sensing shell over it. This consolidation creates a unified control interface that enhances usability while avoiding the need for separate, complex control mechanisms.
Solution Approach 2:
The flexible printed circuit board serves multiple functions: it provides electrical connections between the touch sensing shell and control circuitry, acts as a structural support for the touch interface, and enables integration into the housing. This multi-functionality reduces the need for additional components, offsetting the increased complexity with functional consolidation.
