Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a three-sectional insulating contact surface is formed in the insertion terminal, then the connection reliability is improved, but the manufacturing difficulty and cost increase
Solution Approach 1:
The contact structure is divided into three separate contact points (first, second, and third contact points) arranged in parallel, each independently connected to the encoding chip. This segmentation allows for simpler individual contact formation while maintaining overall connection reliability through redundancy and distributed contact.
Solution Approach 2:
The insertion terminal is designed with multi-functionality by integrating both audio/video signal transmission and encoding verification functions into a single component. The terminal can connect various devices (microphones, AV devices, cameras) while simultaneously performing key management through the encoding chip, eliminating the need for separate specialized connectors.
2Reliability
If the insertion terminal is designed for specific device connection, then the connection reliability is improved, but the adaptability decreases
Solution Approach 1:
The insertion terminal incorporates a universal design that can connect to multiple device types including microphones, AV devices, and cameras. The encoding chip provides a standardized interface that works across different device categories, allowing the same terminal to reliably connect various devices without requiring device-specific designs.
Solution Approach 2:
The terminal design allows for flexible adaptation to different connection scenarios. The encoding chip can work with different encoding schemes and the terminal structure accommodates various plug types and connection configurations, enabling the system to dynamically adapt to different device requirements while maintaining reliable connections.
3Measurement precision
If an encoding chip with light emitting body is added to the insertion unit, then the identification capability is improved, but the device complexity increases
Solution Approach 1:
The encoding chip integrates multiple functions including encoding verification, light emission for visual feedback, and electrical contact for signal transmission into a single compact component. The light emitting body (LED) is combined with the encoding circuitry, eliminating the need for separate identification devices and reducing overall system complexity despite enhanced functionality.
Solution Approach 2:
The encoding chip performs self-verification by comparing the input encoding signal with its stored encoding data and provides immediate visual feedback through the light emitting body. This self-service mechanism eliminates the need for external verification devices or complex control systems, as the terminal autonomously validates connections and indicates status through LED lighting.
