Solution Overview
Problem
Traditional multiple flame ring gas burners face challenges such as laborious spot-facing operations for coupling components, constructional inaccuracies like spark gap tolerance issues, limited flexibility to adapt to different market requirements, and complex installation due to large size and precise machining needs.
Innovation Solution
A gas burner design with a burner body composed of two parts, an injector holder cup, and a cover element, featuring reduced spot-facing surfaces and adjustable venturi conduits, allowing for precise positioning of spark plugs and thermocouples, flexibility in air intake direction, and easy injector replacement, while maintaining a compact size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional multiple flame ring burners use separate spot-faced surfaces for coupling components, then coupling seal is ensured, but laboriousness of spot-facing operations increases and coplanarity precision is difficult to achieve
Solution Approach 1:
The patent merges multiple spot-faced surfaces into a single common spot-faced surface on the burner body. Instead of separately spot-facing surfaces on the burner body, injector holder, and flame distribution element, all coupling interfaces use one unified spot-faced surface, eliminating the need to ensure coplanarity between multiple surfaces while maintaining sealing reliability.
Solution Approach 2:
The common spot-faced surface serves multiple coupling functions simultaneously - it provides the sealing surface for the injector holder coupling, the flame distribution element coupling, and ensures coplanarity for all components. This universal surface replaces multiple specialized spot-faced surfaces.
2Adaptability or versatility
If traditional burners use multiple separate components with multiple couplings, then functional requirements are met, but constructional inaccuracies accumulate and spark gap tolerance is compromised
Solution Approach 1:
The patent reduces the number of separate coupling interfaces by using a common mounting surface and integrating the ignition electrode and thermocouple directly into the burner body. This eliminates accumulation of tolerances from multiple coupling interfaces, ensuring precise spark gap positioning.
3Ease of manufacture
If traditional burners are designed with fixed configuration, then manufacturing is simplified, but flexibility to adapt to different market requirements is limited
Solution Approach 1:
The patent enables dynamic configuration by allowing the injector holder and flame distribution element to be positioned at different locations on the common spot-faced surface. The venturi conduits can be oriented in different directions, and the number and arrangement of flame rings can be modified, all while using the same basic burner body structure.
Solution Approach 2:
The burner body with its common spot-faced surface serves as a universal platform that can accommodate different injector configurations, flame distribution patterns, and ignition system arrangements to meet various market requirements without requiring completely different burner designs.
4Reliability
If traditional burners require large size and precise machining, then coupling seal is ensured, but installation complexity increases
Solution Approach 1:
The patent consolidates multiple precision machining requirements into a single common spot-faced surface on the burner body, reducing installation complexity while maintaining sealing reliability. The unified surface is easier to machine and install than multiple separate precision surfaces.

Implementation Method 1
The burner body, which in certain cases is produced as a single piece with the injectors, comprises one or more venturi conduits, in which the gas is mixed with primary air entrained by the gas itself which leaves the injectors
Implementation Method 2
the electrode of the ignition spark plug, which is generally applied to the injector holder, and the burner surface, to which it discharges the spark
