Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If FPC is used as a heater to enable computer operation in low-temperature environments, then the computer can be powered on and operate normally, but the cost of the FPC increases and heating efficiency needs improvement
Solution Approach 1:
The invention utilizes the existing power supply module's power supply element to serve dual purposes: normal power supply and heating. The power supply element automatically provides heating function when the system detects low-temperature conditions preventing normal operation, eliminating the need for separate heating components. This self-service approach resolves the contradiction by making the existing component serve multiple functions without adding external heating devices.
Solution Approach 2:
The power supply element is designed to perform both its primary function of providing electrical power and a secondary function of heating when needed. By controlling the power supply element to operate in heating mode during low-temperature power-on scenarios, the invention achieves multi-functionality without requiring separate heating elements, thus reducing device complexity while maintaining reliability.
2Temperature
If FPC is used as a heater, then heating can be provided, but the cost increases and heating efficiency is insufficient
Solution Approach 1:
The power supply element inherently possesses the capability to generate heat as a byproduct of its electrical operation. By controlling the power supply module to deliver controlled power cycles to the power supply element, the system efficiently converts electrical energy to thermal energy using an existing component, achieving high heating efficiency without the need for dedicated heating elements like FPC heaters.
Solution Approach 2:
The invention changes the operational parameters of the power supply element by controlling the frequency and duration of power supply cycles. By adjusting these parameters, the system optimizes the heat generation efficiency of the power supply element, enabling effective heating while maintaining cost-effectiveness and avoiding the inefficiencies associated with traditional FPC heating solutions.
