Solution Overview
Problem
Existing heating units lack compactness and efficient control over heating power, making it difficult to adapt to varying volume flows and maintain consistent flow temperatures.
Innovation Solution
A compact heating unit with a plastic housing and a heating flange that includes independently controllable first and second pipe radiators, allowing for precise electrical power control in 1 kW steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a compact heating unit design is implemented, then the device size is reduced, but the heating power control precision deteriorates
Solution Approach 1:
The heating element is divided into multiple independent heating zones (first heating elements and second heating elements) that can be controlled separately. This segmentation allows precise control of total heating power by selectively activating different zones, maintaining control precision while enabling compact integration of multiple heating functions in a single unit.
2Adaptability or versatility
If multiple heating elements with different powers are used, then the heating output adjustability is improved, but the device complexity increases
Solution Approach 1:
Different heating zones are designed with different power outputs (first heating elements with first heating power, second heating elements with second heating power greater than the first) to match different heating demands. This local quality differentiation provides versatile heating output adjustment while maintaining a relatively simple overall structure through standardized modular heating element design.
