Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fuel gas switches lack clear indication of their open or closed status, leading to potential hazards due to misjudgment during operation.
Innovation Solution
A valve structure with integrated identification members that visually indicate the open or closed status through the protrusion and retraction of an identification part or first identification part relative to a combination or assembly hole, utilizing magnetic interaction in the second embodiment, ensuring accurate switch operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional switches are used without identification indicators, then the device complexity is low, but the reliability of switch status indication is poor leading to misjudgment
Solution Approach 1:
The identification member utilizes visual appearance changes (protrusion and retraction) to indicate different switch statuses. When the valve knob rotates to different positions, the identification member相应地 protrudes or retracts, providing clear visual feedback to users about the current valve state without requiring complex electronic indicators.
Solution Approach 2:
The valve structure is divided into functional segments: the valve body, valve knob, control component, and identification member. The identification member is further segmented into an identification part and a braking part, allowing independent functions for status indication and mechanical braking respectively, thereby improving reliability while maintaining manageable complexity.
2Loss of information
If an identification member is added to indicate switch status, then the reliability of status determination improves, but the device complexity increases
Solution Approach 1:
The identification member is integrated into the valve knob assembly, combining the status indication function with the existing operating mechanism. The identification part works together with the braking part within the same component structure, eliminating the need for separate indication devices and minimizing overall structural complexity.
Solution Approach 2:
The identification member provides status information through dimensional change (protrusion and retraction along the axial direction) rather than through rotational position or color change. This vertical dimension of movement offers clear visual feedback while utilizing the existing rotational motion of the valve knob, avoiding the need for additional indication mechanisms.
3Ease of operation
If the identification member uses magnetic interaction, then the ease of operation improves with automatic positioning, but the device complexity increases
Solution Approach 1:
The magnetic interaction mechanism replaces complex mechanical positioning systems with a simpler magnetic field-based approach. The magnetic attraction and repulsion forces automatically position the identification member without requiring precision-machined mechanical guides or springs, thereby improving ease of operation while keeping the overall structure relatively simple.

AI summary
The present invention relates to a valve structure with switch identification, which is implemented by multiple embodiments. By the identification member or the first identification member (5) , the rotation operation of the valve knob (3) enables protrusion and retraction of the identification member or the first identification member relative to the combination hole (33) or the first assembly hole, along with the upward or downward displacement of the valve knob resulting from its upward or downward rotation. This allows users to quickly visually identify whether the inside of the valve body is open or close, ensuring safety in use and preventing dangers.
