Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas grill control devices lack ease of installation, integration of all necessary components, and provide inadequate tactile feedback for setting timing functions, making them difficult for non-professionals to use effectively.
Innovation Solution
A control valve and timer device kit that includes a control valve, timer, gas control dial, and necessary fittings and tools, designed for easy installation and featuring a tactile dial with segment notches for intuitive time setting without visual reference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing gas grill control devices are used, then gas flow control is provided, but ease of installation and user-friendliness deteriorate due to lack of integrated components and inadequate tactile feedback
Solution Approach 1:
The patent combines the control valve, timer, and all necessary fittings (flare fittings, hoses, connectors) into a single integrated kit. This merging of components resolves the technical contradiction by providing ease of installation through a complete pre-assembled unit while maintaining the necessary functional complexity of gas flow control and timing operations.
Solution Approach 2:
The control device serves multiple functions simultaneously: it controls gas flow, provides timing functionality, and includes all installation components. This multi-functionality addresses the contradiction by consolidating what would otherwise require separate devices and components into one universal unit that handles installation and operation comprehensively.
2Ease of operation
If existing control devices are used, then gas flow control is provided, but tactile feedback for setting timing functions deteriorates
Solution Approach 1:
The dial is segmented into distinct tactile zones corresponding to different timing intervals. Each segment provides unique tactile feedback through raised markings and directional grooves, allowing users to easily identify and select timing settings without visual reference. This segmentation resolves the contradiction by providing intuitive tactile guidance while maintaining a relatively simple rotary control interface.
Solution Approach 2:
Different regions of the dial possess distinct tactile properties - some areas have raised markings, others have grooves or varying surface textures. This local differentiation of tactile quality enables users to feel their way to the correct timing setting, resolving the contradiction between providing detailed control feedback and keeping the interface simple.
3Reliability
If automated control valve is used, then gas shut-off function is provided, but ease of use deteriorates due to complex installation requirements
Solution Approach 1:
All necessary components for installation are pre-assembled and pre-configured in the kit before reaching the user. The flare fittings, hoses, and connectors are prepared in advance, eliminating the need for users to perform complex assembly operations. This preliminary action resolves the contradiction by maintaining reliable automatic shut-off functionality while dramatically simplifying the installation process.
Solution Approach 2:
The kit is designed to be self-installing, with all components included and configured for direct installation by the end user without requiring professional assistance. The standardized fittings and pre-assembled nature of the kit enable non-professionals to complete installation themselves, resolving the contradiction between providing reliable automated control and ensuring ease of installation.

AI summary
The invention relates to a control valve system for use with a gas grill, and more particularly to a fuel shut off device that is attached to the fuel supply to turn it off, if the integrated timing device is allowed to accrue time equal to the preset amount of time set. A multi-segment tactile dial enables a user to feel the dial and set the appropriate time increment without having to look at the dial.
