Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In water heating devices, burner units that are too close can generate excessively strong heat, weakening components like heat exchangers, while units that are too far apart may not produce sufficient heat for effective water heating.
Innovation Solution
A burner assembly with burner units positioned at a minimized interval, utilizing a flow passage guide separate from the case to maintain a predetermined separation distance between units, ensuring stable combustion and efficient heat distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If burner units are positioned close to each other to maximize heat generation, then thermal power is improved, but flame merging occurs causing harmful effects on component durability
Solution Approach 1:
A flow passage guide is introduced as an intermediary component between adjacent burner units. This guide includes flow passages that direct fuel flow and create a physical separation effect, preventing flames from merging while maintaining close positioning of burner units for maximum thermal efficiency.
Solution Approach 2:
The flow passage guide divides the fuel flow into separate channels for each burner unit. By segmenting the fuel supply path, the design ensures that each burner receives fuel in a controlled manner that prevents flame interaction, allowing burner units to be positioned closer without causing harmful flame merging.
2Productivity
If burner units are positioned at minimized intervals to increase heat concentration, then productivity is improved, but reliability of heat exchanger components deteriorates
Solution Approach 1:
The flow passage guide serves as a mediator that enables close positioning of burner units for high productivity while protecting the heat exchanger from excessive heat concentration. The guide structure controls fuel distribution and flame patterns to maintain reliable operating conditions.
Solution Approach 2:
The design changes the fuel flow parameters through the flow passage guide, creating optimized flow patterns that maintain stable combustion. This allows burner units to operate at minimized intervals for high productivity while the controlled fuel delivery prevents harmful heat concentration that would compromise heat exchanger reliability.
3Strength
If burner units are positioned far apart to prevent flame merging, then component durability is improved, but thermal power output decreases
Solution Approach 1:
The flow passage guide acts as an intermediary that enables close positioning of burner units without causing flame merging. This intermediary structure directs fuel flow in a way that maintains component durability while maximizing heat generation through optimized burner placement.
