Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the aerosol-generating device is frequently used to generate aerosol, then the productivity and usage frequency increase, but the lifetime of the energy storage decreases due to excessive charging and discharging
Solution Approach 1:
The system performs preliminary actions by receiving a limitation parameter before excessive usage occurs, and proactively controls the energy storage to prevent degradation. The device limits charging cycles or discharge depth in advance based on the received parameter, thereby extending energy storage lifetime while allowing maximum sustainable productivity.
Solution Approach 2:
The system implements feedback control by continuously monitoring energy storage status (charge cycles, discharge depth, temperature) and adjusting operation accordingly. The device control circuitry uses the limitation parameter to dynamically control charging/discharging processes, ensuring optimal balance between productivity and reliability through real-time feedback on energy storage health.
2Ease of operation
If the device allows unlimited operation, then the ease of operation and user convenience increase, but the loss of time for device replacement increases
Solution Approach 1:
The system performs preliminary maintenance by receiving and processing the limitation parameter before the energy storage degrades to failure. This proactive approach allows the device to operate at full capacity within safe limits, preventing premature replacement and reducing user downtime.
Solution Approach 2:
The device automatically manages its own energy storage lifecycle by controlling charging/discharging based on the limitation parameter. The system self-regulates operation to extend its own service life, eliminating the need for user intervention in maintenance scheduling and reducing replacement frequency.
3Use of energy by moving object
If the energy storage is fully utilized, then the use of energy increases, but the reliability of continuous operation decreases due to faster degradation
Solution Approach 1:
The system dynamically adjusts energy utilization based on the limitation parameter and real-time energy storage status. The device control circuitry modifies charging/discharging rates and depth according to current conditions, optimizing the balance between immediate energy use and long-term reliability through adaptive, dynamic control rather than fixed utilization patterns.
