Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If flue pipes are connected in series using non-standard pipes or assembled by workers without professional training, then installation cost is reduced, but connection stability deteriorates and gas leakage risks increase
Solution Approach 1:
The patent applies preliminary action by pre-equipping flue pipes with electrical conductors and connectors before installation. The electrical connection is prepared in advance, so that when pipes are connected, the electrical continuity is automatically established, providing immediate verification of proper mechanical connection without requiring post-installation testing or adjustment by untrained workers
Solution Approach 2:
The patent implements feedback by using the electrical conductor system to provide real-time verification of connection status. The electrical continuity serves as feedback that confirms proper mechanical connection, allowing immediate detection of connection problems and enabling the control system to take corrective action, thereby maintaining high reliability even with non-standard installation practices
2Adaptability or versatility
If flue pipes with fixed length are cut short to adjust overall length, then adaptability to different installation situations is improved, but the electrical conductor connection is compromised
Solution Approach 1:
The patent applies segmentation by dividing the flue pipe system into modular sections, each with its own electrical conductor and connector. This allows individual pipe segments to be cut or replaced independently while maintaining electrical continuity through the connector system, enabling length adjustment without compromising overall electrical connection integrity
Solution Approach 2:
The patent enables parameter changes by allowing physical modification of pipe length while maintaining the electrical connection parameter through standardized connectors. The electrical conductor system is designed to accommodate length variations, so the electrical connection parameter remains stable even when pipe dimensions are modified for different installation requirements
3Reliability
If a switch assembly with proximity switch and detector is added to detect flue pipe connection, then connection reliability is improved, but device complexity increases
Solution Approach 1:
The patent merges the connection detection function with the existing electrical conductor system. The electrical conductor that serves the primary function of exhaust gas transport also serves as the detection medium, eliminating the need for separate detection components and reducing overall system complexity while maintaining high detection accuracy
Solution Approach 2:
The patent applies universality by designing the electrical conductor system to perform multiple functions: it serves as both the exhaust gas transport medium and the connection detection sensor. This multi-functional design eliminates redundant components and simplifies the overall system while providing reliable connection detection through the dual-purpose electrical conductor

Function Achieved in This Case
The system effectively detects and ensures a reliable connection between the gas appliance and the flue pipe assembly, preventing gas leakage and enhancing safety by activating the control unit when a secure connection is established.
Implementation Method 1
the switch assembly includes a proximity switch and a detector, wherein one of the proximity switch and the detector is fixed relative to the housing, and the other of the proximity switch and the detector is retained to the first flue pipe. In the course of the first flue pipe being connected to the flue hood, the proximity switch is activated when the detector approaches the proximity switch to a predetermined distance.
