Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical switches are used to control electronic cigarette functions, then the device can be operated and controlled, but the mechanical switches produce annoying click sounds and are prone to failure over time
Solution Approach 1:
The patent replaces mechanical switches with a pressure sensor-based sensing system. The pressure sensor detects user input through pressure changes without mechanical contact, eliminating the click sounds and mechanical wear associated with traditional switches. This substitution of mechanical system with a sensing-based system resolves both the noise and reliability issues.
2Adaptability or versatility
If multiple mechanical switches are used to achieve various functions, then the device can provide diverse operations, but the device complexity increases and user experience deteriorates
Solution Approach 1:
The patent implements a universal pressure sensor-based control system that can detect different pressure levels, durations, and patterns to trigger multiple functions. Instead of requiring separate mechanical switches for each function, a single pressure sensor handles all control operations, reducing device complexity while maintaining versatility through software-based function differentiation.
3Duration of action of moving object
If mechanical switches are used for long-term operation, then the device can be used repeatedly, but the mechanical switches are prone to failure after long-term use
Solution Approach 1:
The patent replaces mechanical switches with a pressure sensor that has no moving mechanical parts. The sensor detects user input through electrical resistance changes in a flexible substrate, eliminating mechanical wear and contact fatigue. This enables long-term reliable operation without the degradation issues inherent in mechanical switch systems.
