Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In compact hot water tank assemblies, the close proximity of heater lines leads to excessive bubble generation and superheated steam production, causing overheating and noise issues, while also increasing power consumption and reducing purified water efficiency.
Innovation Solution
The hot water tank assembly features a heating heater with intersecting portions between heater lines, minimizing interference and reducing overheating and bubble generation, while maintaining efficient heating and reducing noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If heater lines are disposed in multiple rows with small gap to improve heating efficiency, then heating efficiency is improved, but interference between heater lines increases causing excessive bubble generation and superheated steam
Solution Approach 1:
The heater lines are arranged in multiple rows along the width direction of the hot water tank, utilizing the width dimension to increase heating surface area. The intersecting portions are positioned at specific locations where they do not face each other, maintaining adequate spacing in the width direction while maximizing heating efficiency through multi-row configuration.
Solution Approach 2:
The heater lines are designed with asymmetric intersecting portions that are offset from the centerline of the tank. This asymmetric arrangement ensures that intersecting portions do not face each other directly, reducing interference and bubble generation while maintaining effective heating coverage throughout the water volume.
2Productivity
If heater lines are disposed close to wall surface to improve heating efficiency, then heating efficiency is improved, but soot generation on wall surface increases
Solution Approach 1:
The heater lines are positioned to maintain an optimal distance from the wall surface, neither too close nor too far. The intersecting portions are specifically arranged to avoid close proximity to the wall, creating local quality variations in the heating arrangement that prevent soot generation while maintaining overall heating efficiency through adequate heat distribution.
3Productivity
If power of hot water tank is increased to improve heating efficiency, then heating efficiency is improved, but bubble generation and superheated steam increase
Solution Approach 1:
The heating function is segmented into multiple independent heater lines arranged in parallel rows. Each heater line operates as a separate heating element, distributing the total power input across multiple segments. This segmentation prevents concentrated overheating and reduces bubble generation even at high power levels, while maintaining overall heating efficiency through the combined effect of multiple heating zones.
