Cap to change inner flame burner to vertical flame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current gas burners lack the ability to control flame direction, limiting both functional and aesthetic options for users, as they rely solely on individual burner knobs for flame manipulation.
Innovation Solution
A burner cap set for gas burners that includes a spreader and crenellated wall with fuel exit ports directing flames inwardly or upwardly, allowing for the selection between an inner flame state and a vertical flame state through interchangeable inner and vertical flame burner caps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional gas burners are used with individual burner knobs, then the burner structure remains simple, but the flame control capability is limited
Solution Approach 1:
The burner cap is divided into multiple segments that can be independently rotated and positioned. Each segment contains fuel exit ports oriented in different directions, allowing selective activation of specific flame patterns (e.g., inner flame, vertical flame, combination flame) by rotating the cap to different angular positions, thereby providing versatile flame control without complex mechanisms
Solution Approach 2:
The burner cap is designed with rotational freedom, transforming from a static component to a dynamic one. The cap can be rotated to different angles and locked into position, enabling the fuel exit ports to be dynamically oriented toward different directions (inward for inner flame, upward for vertical flame, or both simultaneously), thus providing multiple flame control modes through a single movable component
2Adaptability or versatility
If multiple flame states are implemented with interchangeable caps, then flame control versatility is improved, but the device complexity increases
Solution Approach 1:
The burner cap is designed as a universal component that integrates multiple functions into a single element. By incorporating fuel exit ports in different orientations within the same cap structure and enabling rotational positioning, a single cap design can produce multiple flame states (inner flame, vertical flame, combination flame), eliminating the need for separate interchangeable caps for each flame type
Solution Approach 2:
The invention adds a rotational dimension to the burner cap operation. Instead of requiring multiple separate caps stacked vertically, the cap utilizes angular/rotational positioning to select different flame patterns. This dimensional transformation from vertical stacking to rotational selection simplifies the overall structure while maintaining multiple flame state options
3Productivity
If fuel exit ports are directed inwardly for inner flame state, then cooking efficiency is improved, but heat loss increases
Solution Approach 1:
The burner cap enables dynamic switching between different fuel exit port orientations. When inner flame cooking efficiency is needed, the cap rotates to direct ports inwardly, concentrating heat under the cookware. When heat loss becomes excessive, the same cap can be rotated to direct ports upwardly, creating a vertical flame that reduces heat loss. This dynamic adjustability allows optimization between cooking efficiency and heat loss reduction based on real-time cooking requirements
4Ease of operation
If flame direction is fixed, then the burner structure remains simple, but user control and aesthetics are limited
Solution Approach 1:
The burner cap is designed with rotational freedom, transforming from a static component to a dynamic one. The cap can be rotated to different angles and locked into position, enabling the fuel exit ports to be dynamically oriented toward different directions (inward for inner flame, upward for vertical flame, or both simultaneously), thus providing multiple flame control modes through a single movable component
Solution Approach 2:
The burner cap is divided into multiple segments that can be independently rotated and positioned. Each segment contains fuel exit ports oriented in different directions, allowing selective activation of specific flame patterns (e.g., inner flame, vertical flame, combination flame) by rotating the cap to different angular positions, thereby providing versatile flame control without complex mechanisms
