Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If digital control mechanisms with microcontrollers and software are used, then user experience feedback can be modulated, but aberrant activation and software failures occur leading to safety hazards
Solution Approach 1:
The patent replaces digital control mechanisms with an electromechanical feedback system that uses physical mechanical components (levers, springs, contacts) to control power delivery. This substitution eliminates software and microcontroller dependencies, thereby resolving the reliability issues of aberrant activation while maintaining the ability to modulate user experience through mechanical state changes.
Solution Approach 2:
The system segments the control mechanism into separate mechanical components (inhalation detection lever, haptic feedback lever, power control contacts) that operate independently through physical interactions. This segmentation removes the need for integrated software control, eliminating software failure modes while preserving functional modulation capabilities.
2Measurement precision
If continuous power is supplied to detection devices, then detection accuracy is maintained, but battery life is reduced
Solution Approach 1:
The electromechanical system uses periodic mechanical activation through user inhalation actions to trigger detection and power delivery. The inhalation detection lever is activated only when needed (during inhalation), which periodically powers the detection devices and atomizer only during actual use, thereby maintaining detection accuracy while conserving battery life through on-demand operation.
Solution Approach 2:
The mechanical system is self-activating through the user's own inhalation action, which physically moves the inhalation detection lever to close contacts and activate power delivery. This self-service mechanism eliminates the need for continuous electronic monitoring, enabling detection devices to operate only when triggered by actual user interaction, thus preserving battery life.
