Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If conventional power supply devices are used with fixed internal parameter settings at product release, then device simplicity is maintained, but power efficiency deteriorates under varying load conditions
Solution Approach 1:
The patent implements dynamic adjustment of internal parameters by introducing a receiver that accepts external instructions and a controller that modifies parameter settings in response to changing load conditions or software updates, transforming the previously static power supply device into an adaptive system that optimizes power efficiency across varying operational states
Solution Approach 2:
The patent changes the physical or operational state of internal parameters by storing multiple sets of parameter values in memory and selectively switching between them based on external instructions, allowing the device to optimize its performance characteristics for different load conditions without physical modification
2Adaptability or versatility
If multiple settings for internal parameters are stored and made adjustable, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent applies multi-functionality by enabling the power supply device to serve multiple operational modes through a single unified architecture that stores and switches between different parameter sets, allowing the same hardware to adapt to various load conditions and software configurations without requiring separate dedicated circuits for each mode
Solution Approach 2:
The patent introduces a receiver and controller as intermediary components that mediate between external instructions and the internal parameter storage, providing a controlled interface for switching between different parameter sets while maintaining system manageability and preventing uncontrolled complexity proliferation
3Use of energy by moving object
If dynamic adjustment capability is added through receiver and controller, then power efficiency is improved, but manufacturing complexity increases
Solution Approach 1:
The patent merges the receiver, controller, and parameter storage functions into an integrated semiconductor device structure, combining multiple functional elements into a unified chip design that reduces the number of discrete components and simplifies the manufacturing process while maintaining the dynamic adjustment capability for power optimization
