Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If voltage detection circuit and display circuits are added to the battery terminal, then the ability to detect and display battery and engine voltages is improved, but the device complexity increases
Solution Approach 1:
The voltage detection circuit is designed to perform multiple functions: detecting battery voltage, detecting engine voltage, and providing this information through multiple display circuits. This multi-functionality approach allows a single detection circuit to serve multiple purposes, improving measurement capability without proportionally increasing complexity.
Solution Approach 2:
The main control circuit serves as an intermediary that receives voltage signals from the detection circuit and processes them for display. This intermediary component coordinates between the detection circuit and multiple display circuits, managing the flow of information efficiently.
2Loss of information
If multiple display circuits are added to show battery and engine states, then the information feedback capability is improved, but the device complexity increases
Solution Approach 1:
The display function is segmented into separate display circuits: a battery state display circuit and an engine state display circuit. Each display circuit is dedicated to displaying specific information (battery voltage and engine voltage respectively), allowing information to be presented in an organized, non-overlapping manner that improves readability without requiring a single complex display system.
Solution Approach 2:
Each display circuit is designed to display multiple pieces of related information (both voltage readings and health status indicators) within a single circuit, making each display component multi-functional and reducing the total number of separate display elements needed.
