Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If mechanical brakes are used to achieve deceleration, then deceleration is achieved, but kinetic energy is converted into thermal energy which cannot be effectively recovered
Solution Approach 1:
The brake energy recovery module is designed as an independent, segmented unit that can be installed separately from the existing vehicle systems. The module includes distinct functional components (detecting unit, signal decoder, power converting unit, control unit) that operate independently but coordinate together, allowing it to be integrated into existing electric vehicles without requiring comprehensive system redesign or modification of original vehicle settings.
2Loss of energy
If an independent brake energy recovery module is added to the electric vehicle, then energy recovery capability is improved, but the device complexity increases
Solution Approach 1:
The patent merges multiple functions into a single integrated brake energy recovery module. The detecting unit, signal decoder, power converting unit, and control unit are combined into one cohesive system that handles detection, signal processing, power conversion, and control operations. This consolidation reduces the need for separate independent systems while maintaining full energy recovery functionality, thereby managing device complexity effectively.
Solution Approach 2:
The brake energy recovery module is designed with multi-functionality to handle various operating conditions (cruising, gliding, braking) through a single unified system. The control unit can switch between different operational modes and the power converting unit can adapt to different voltage requirements, making the module universally applicable across different vehicle states without requiring multiple specialized systems.
3Productivity
If the motor module voltage is adjusted to charge the battery during braking, then energy recovery is achieved, but the control system complexity increases
Solution Approach 1:
The control unit implements feedback mechanisms by continuously monitoring the first voltage from the motor module and the state of the battery module. Based on this feedback, the control unit dynamically adjusts the power converting unit to optimize voltage conversion and charging parameters. This feedback loop enables efficient energy recovery while maintaining straightforward control logic that responds automatically to real-time system conditions.
