Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If the capacity of the energy storage component is increased to ensure adequate power failure holding time for high power consumption network devices, then the power failure holding time is improved, but the volume and layout space of the chip are worsened
Solution Approach 1:
The patent combines the power boost function and energy storage function into a single integrated circuit module. The boost unit increases the source voltage to charge the energy storage unit more efficiently, allowing the same energy storage capacity to be achieved with a smaller physical component. This merging of functions resolves the contradiction by enabling adequate power failure holding time without increasing the volume of the energy storage component.
Solution Approach 2:
The patent changes the voltage parameter by introducing a boost unit that increases the source voltage before it charges the energy storage unit. By charging at a higher voltage, the same amount of energy can be stored in a smaller capacitor (since Energy = 0.5 * C * V^2). This parameter change allows the system to maintain adequate power failure holding time while reducing the volume of the energy storage component.
2Use of energy by moving object
If additional power boost chips are added to boost the source voltage for charging the energy storage unit, then the charging efficiency is improved, but the device complexity and cost are worsened
Solution Approach 1:
The patent merges the power boost function and energy storage function into a single integrated circuit module, eliminating the need for separate power boost chips. The boost unit is designed to work specifically with the energy storage unit within the same module, simplifying the overall system architecture while maintaining high charging efficiency. This integration resolves the contradiction by improving charging efficiency without adding device complexity.
Solution Approach 2:
The integrated circuit module performs multiple functions within a single device: voltage boosting, energy storage, and power management. The boost unit can charge the energy storage unit at optimized voltage levels, and the same module manages power distribution during normal operation and power failure conditions. This multi-functionality resolves the contradiction by achieving efficient charging without requiring additional specialized components.
