Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the timer and valve body are precisely calculated and managed for accurate timing operation, then the timing accuracy is improved, but the timer becomes applicable only to one type of valve body, increasing fabrication cost and reducing flexibility
Solution Approach 1:
The timer is designed with a universal interface system comprising a guide plate with guide holes and a push bar with a push head that can interface with different valve plug assemblies. The guide plate can be selectively replaced or adjusted to accommodate different valve body types, allowing the same timer mechanism to accurately control timing for multiple valve configurations without requiring complete redesign.
Solution Approach 2:
The timer system is divided into modular components: the core timing mechanism (gear drive, cam, push bar) remains constant, while the interface components (guide plate, guide holes, push head) can be segmented and reconfigured. This segmentation allows the timer to maintain accurate timing operation while adapting to different valve body types by simply changing the guide plate configuration.
2Adaptability or versatility
If the valve body shape or size is changed or re-designed, then the valve body adaptability is improved, but the timer has to be re-designed, increasing fabrication cost and reducing throughput
Solution Approach 1:
The timer employs a universal mounting and actuation system where the guide plate can be positioned at different locations and the push bar can be adjusted to reach different valve plug assemblies. This universal interface allows the same timer design to work with various valve body shapes and sizes without requiring custom timer designs for each valve type.
Solution Approach 2:
The timer system allows for parameter adjustments in the interface components, such as the position of guide holes in the guide plate, the length and angle of the push bar, and the position of the push head. These parameter changes enable the timer to adapt to different valve body configurations while maintaining the same core timing mechanism, thereby avoiding costly redesigns.
3Measurement precision
If the push bar length and rotation angle are precisely determined for a specific valve body, then the timing operation accuracy is improved, but the timer cannot be commonly used with other valve bodies
Solution Approach 1:
The push bar is designed with dynamic adjustment capabilities, allowing its effective length and rotation angle to be modified based on the specific valve body configuration. The guide plate can be repositioned and the push bar can be adjusted to achieve the correct geometry for accurate timing operation with different valve types, making the timer both precise and versatile.

Function Achieved in This Case
The timer can now be used with multiple types of valve bodies, ensuring safe and error-free timing of fuel gas usage, while reducing fabrication costs and improving performance and throughput.
Implementation Method 1
The spring 253 has an end supported on a bottom surface of the valve plug ring 252, and the spring 253 has an opposite end supported on an internal bottom surface 273 of the tube plug 27, and the spring 253 is also fit to and encompasses an outer circumferential surface of the raised tube 271 in the center of the tube plug 27. The valve plug ring 252 is biased by a spring force of the spring 253 so as to block and close the valve aperture 24

AI summary
A timer applicable to various types of fuel gas valves and a fuel gas valve including the timer are provided. The timer includes a rotary knob, a gear-set main body, a guide plate including a guide tube, a push axle, and an elastic element. The timer is combinable with a valve body to form a fuel gas valve. With the guide plate including the guide tube in which the push axle is disposed, a push bar of the timer may push the push axle to accurately drive a valve plug assembly arranged in the valve body to open and shut down a flow passage of the valve body between an entry opening and an exit opening. This allows one single timer to be applicable to various types of valve body and a fuel gas valve including the timer enables use of fuel gas in a safe and correctly timing manner.
