Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric radiators in heating, ventilation, and air-conditioning systems face issues with electrical connections being exposed to air flow and potential humidification, leading to degradation and reduced heating surface efficiency.
Innovation Solution
The electrical connections between heating elements and the printed circuit board are optimized by arranging them in a connection tube parallel to the heating elements, protecting them from the external environment and maintaining air flow homogeneity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electrical connection extends through the frame of the heating body to connect the opposite longitudinal end of the resistive element to the printed circuit board, then the electrical connection is established, but the connection is exposed to air flow and humidification leading to degradation and break
Solution Approach 1:
The electrical connection member is nested inside the connection tube, which extends parallel to the heating elements. This nesting arrangement protects the electrical connection from direct exposure to air flow and humidification while maintaining the electrical connection between the printed circuit board and the resistive element at the opposite longitudinal end.
2Reliability
If the electrical connection extends through the frame of the heating body, then the connection is established, but the effective heating surface is reduced
Solution Approach 1:
Instead of extending the electrical connection through the frame in a manner that reduces heating surface area, the connection tube is positioned to run parallel to the heating elements, utilizing the longitudinal dimension. This dimensional arrangement minimizes the impact on the effective heating surface while establishing the necessary electrical connection.
3Volume of moving object
If the heating body is made compact, then the bulk-to-surface ratio is optimized, but the arrangement of electrical connections becomes more difficult
Solution Approach 1:
The connection tube is merged with the structural framework of the heating body, extending parallel to the heating elements and integrating the electrical connection path into the overall compact design. This merging allows the electrical connection to be established without significantly increasing the bulk of the heating body, thus optimizing the bulk-to-surface ratio while maintaining connection reliability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This arrangement prevents connection degradation, maintains heating efficiency, and makes the heating body more compact by optimizing the bulk-to-surface ratio.
Implementation Method 1
all the resistive elements within the heating elements are supplied with the same electric current passing through this connection, so that a substantially uniform amount of heat is released over the entire main extension dimension of the heating element
