Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rechargeable battery is used for power supply, then the device can be charged and reused, but the operating time is limited and the battery may deplete leading to device failure
Solution Approach 1:
The power supply system is segmented into two independent battery units: a rechargeable battery for regular operation and a primary battery for backup. This segmentation allows each battery type to fulfill its specific function optimally, with the rechargeable battery providing daily power needs and the primary battery ensuring extended operation during depletion scenarios.
Solution Approach 2:
The primary battery is pre-installed and pre-charged within the device as a backup power source. The electronic control unit is pre-programmed to automatically detect rechargeable battery depletion and switch to the primary battery, eliminating the need for manual intervention and ensuring continuous operation without interruption.
2Ease of operation
If the rechargeable battery is permanently installed, then manual battery changes are eliminated improving safety, but the battery cannot be replaced when depleted
Solution Approach 1:
A primary battery is pre-installed within the device as a permanent backup component. When the rechargeable battery depletes, the system automatically switches to the primary battery, ensuring continuous operation without requiring manual battery replacement. This preliminary preparation of a backup power source resolves both the ease of operation and extended operating time requirements.
Solution Approach 2:
The electronic control unit acts as an intermediary between the rechargeable and primary batteries, automatically detecting the charge status of the rechargeable battery and switching power sources as needed. This intelligent mediation eliminates manual intervention while ensuring seamless transition between power sources, maintaining both operational simplicity and extended functionality.
3Duration of action of moving object
If a primary battery is used instead of rechargeable, then the operating time is extended, but the battery cannot be recharged and must be replaced manually
Solution Approach 1:
The power supply system is divided into two functional segments: a rechargeable battery segment for regular recharging cycles and a primary battery segment for extended backup operation. This segmentation allows the device to benefit from both rechargeable convenience and primary battery longevity, with the electronic control unit managing transitions between segments based on charge status.
Solution Approach 2:
The electronic control unit serves as an intelligent intermediary that monitors the rechargeable battery's charge level and automatically switches to the primary battery when depletion is detected. This automated mediation eliminates the need for manual battery replacement while maximizing operating time, as the system seamlessly transitions to the long-lasting primary battery source.
4Duration of action of moving object
If manual battery changes are allowed, then depleted batteries can be replaced, but safety risks increase especially in explosive environments
Solution Approach 1:
A primary battery is pre-installed as a permanent backup component within the device housing, eliminating the need for users to manually access or replace batteries in potentially explosive environments. The automatic switching mechanism ensures that when the rechargeable battery depletes, the system transitions to the pre-positioned primary battery without requiring user intervention, thereby maintaining safety while extending operating time.
Solution Approach 2:
The power supply system performs self-service through automatic detection and switching between the rechargeable and primary batteries. The electronic control unit continuously monitors battery status and autonomously manages the transition between power sources, eliminating manual battery handling operations that would pose safety risks in explosive atmospheres while ensuring continuous operation.
