Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a modular electronics unit with separate terminal space and electronics space is used, then explosion-proof safety is improved by preventing explosion spread, but device complexity increases due to the need for partition walls and separate mounting
Solution Approach 1:
The patent combines the terminal space and electronics space into a single housing without a partition wall. The first electronic device (terminal device) and second electronic device (electronics unit) are mounted in the same housing and connected via a detachable contacting unit, eliminating the need for complex partition structures while maintaining explosion-proof safety through adequate separation distances between circuits.
Solution Approach 2:
The patent segments the electronic devices into separate modular units (first electronic device for terminals and second electronic device for sensor control) that can be independently mounted and replaced. This modular approach allows maintenance and replacement without affecting the entire device, while the detachable contacting unit enables easy disconnection.
2Reliability
If electronic devices are firmly connected to ensure stable electrical connection, then connection reliability is improved, but ease of repair and component exchange deteriorates
Solution Approach 1:
The patent employs a detachable contacting unit with plug connections that provides stable electrical connection during operation but allows easy disconnection when needed. This dynamic connection system enables the first and second electronic devices to be firmly connected during use for reliability, yet easily separated for repair or replacement.
Solution Approach 2:
The detachable contacting unit acts as an intermediary between the first electronic device and second electronic device. It provides stable electrical connection through properly designed contact elements while enabling easy separation for maintenance, thus mediating between the requirements for connection stability and repairability.
3Reliability
If adequate separation distances are maintained between circuits for intrinsic safety, then explosion-proof safety is improved, but device complexity increases due to spacing requirements
Solution Approach 1:
The patent extracts the high-voltage terminal circuits and low-voltage sensor control circuits into separate modular electronic devices. By physically separating these circuits into different devices connected via detachable contacting unit, adequate separation distances for intrinsic safety are naturally achieved without complex layout constraints within a single circuit board.
