Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional wired or wireless communication networks are used for master BMS to communicate with slave BMSs, then operation mode shifting can be achieved, but communication interference and delays occur
Solution Approach 1:
The patent replaces the conventional wired communication network with an optical communication system using light emitting units and light receiving units. This substitution eliminates communication interference and delays associated with electrical networks, achieving instant signal transmission between master and slave BMSs.
Solution Approach 2:
The patent introduces light as an intermediary medium for communication between master and slave BMSs. The light emitting unit converts electrical signals to optical signals, and the light receiving unit converts them back, serving as an intermediary that prevents direct electrical interference while enabling instant communication.
2Ease of operation
If hardware circuits for storing identification information are added, then slave BMS identification can be achieved, but device complexity increases
Solution Approach 1:
The slave BMS uses its own light receiving unit to detect and recognize the identification signal emitted by the master BMS. This self-service approach eliminates the need for separate hardware storage circuits, as the identification is achieved through optical signal detection and processing.
Solution Approach 2:
The patent replaces hardware storage circuits with an optical signal-based identification system. The master BMS emits identification information through light emitting units, and slave BMSs receive and process this information optically, eliminating the need for physical storage hardware.
3Extent of automation
If high-performance processors are used to execute complex software algorithms, then operation mode shifting can be achieved, but device complexity and cost increase
Solution Approach 1:
The patent replaces complex software algorithms executed by high-performance processors with a simplified optical signal detection and recognition system. The slave BMS uses its light receiving unit to detect the master's optical signals and automatically responds based on pre-defined optical communication protocols, reducing processor requirements.
Solution Approach 2:
The patent uses optical signal patterns (flickering patterns) to encode identification and control information. Instead of complex software processing, the system copies and transmits information through standardized optical patterns that can be recognized and responded to with simple logic.
4Reliability
If additional hardware is added for signal transmission, then communication reliability can be improved, but device complexity increases
Solution Approach 1:
The patent makes the light emitting unit and light receiving unit multi-functional components. These units serve both as communication channels for operation mode shifting and as identification signal transmitters, eliminating the need for separate hardware circuits for different functions.
Solution Approach 2:
The patent merges the communication function and identification function into a single optical system. The same light emitting unit transmits both control signals and identification information, and the light receiving unit receives both types of signals, reducing overall hardware complexity.
