Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional overlapping elongated and round burners are used, then versatility in heating different cooking implements is provided, but device complexity and performance limitations occur
Solution Approach 1:
The patent combines the functions of separate round and elongated burners into a single integrated burner assembly. The spreader defines both a round central burner portion and elongated extension sections that protrude laterally, merging multiple burner functions into one unified structure that heats different cooking implements without requiring multiple separate burners
Solution Approach 2:
The burner assembly is designed to perform multiple functions: the round central portion heats round cookware while the elongated extension sections heat elongated cooking implements. This multi-functional design allows a single burner to replace what would traditionally require multiple separate burners, reducing overall device complexity while maintaining versatility
2Adaptability or versatility
If conventional overlapping burners are used, then various cooking implements can be heated, but flame overlap and inconsistent flame profile occur
Solution Approach 1:
The burner is segmented into distinct functional zones: a round central burner portion and separate elongated extension sections. Each segment has its own fuel outlets and combustion chamber portions, allowing independent flame control. This segmentation prevents flame overlap by creating spatially separated combustion zones that deliver consistent, non-overlapping flames to different cooking surfaces
Solution Approach 2:
Different portions of the burner are optimized for different cooking needs: the round central portion provides concentrated heat for round cookware while the elongated extension sections provide distributed heat for elongated implements. Each segment's geometry and fuel outlet arrangement is specifically designed to produce the appropriate flame characteristics for its intended cooking application, ensuring consistent flame profiles across all cooking zones
3Adaptability or versatility
If elongated burners with smaller extensions are used, then elongated cooking implements can be heated, but performance limitations occur
Solution Approach 1:
The burner design extends from a two-dimensional round base into a three-dimensional configuration with lateral elongated sections. The spreader defines a round central combustion chamber and extends laterally to form elongated combustion chambers that protrude from the central portion. This dimensional expansion allows the burner to accommodate both round and elongated cooking implements simultaneously, eliminating performance limitations while maintaining reliability through proper spatial separation of combustion zones

AI summary
A cooking burner (10) includes a spreader (12) defining a first side wall (14) defining an outer profile (16) having first and second extension sections (18, 20) opposed about a first axis (22). The spreader (12) further defines first and second arced sections (32a, 32b), each extending outwardly along a second axis (34) perpendicular to the first axis (22) from and between parallel straight segments (28a, 28b, 30a, 30b) of the first and second extension sections (18, 20), respectively. The spreader (12) further defines a second side wall (36) disposed inwardly of and concentric with the first and second arced sections (32a, 32b) and a plurality of fuel outlets (40) extending through both the first side wall (14) and the second side wall (36). A circular inner cap (42) is assembled with an upper portion of the circular inner profile, an annular outer cap (44) is assembled with respective upper portions of the first and second arced sections (32a, 32b), and first and second extension caps (46, 48) assembled with respective upper portions of the first and second extension sections (18, 20).
