Solution Overview

Problem

Conventional housing assemblies for HVAC systems' heater cores face electrical leakage issues due to adjacent wire connections, which can lead to short-circuiting and are cumbersome to connect.

Innovation Solution

A housing assembly with laterally offset terminals on a protruded portion and the main housing, respectively, connected to bus bars that power the heater core, eliminating the risk of electrical leakage and simplifying the connection process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If both wires enter the housing from one side to connect with bus bars, then the connection process becomes cumbersome and electrical leakage risk increases, but the housing structure remains simple

Engineering Contradiction:
Improveelectrical insulationVSAvoidconnection process
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent applies dimensional separation by having first and second wires enter the housing from opposite sides (first side and second side respectively) rather than from the same side. This spatial redistribution in multiple dimensions separates the terminal connections, eliminating electrical leakage risk while simplifying the connection process through natural wire routing paths.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Volume of stationary object

If terminal connections are placed adjacent to each other, then the housing structure is compact, but electrical leakage and short-circuiting risks increase

Engineering Contradiction:
Improvehousing compactnessVSAvoidelectrical insulation
Core Design Contradiction:
Volume of stationary objectVSReliability

Solution Approach 1:

The patent segments the terminal connection locations into distinct spatial zones by having wires enter from opposite sides of the housing. This segmentation separates the first terminal and second terminal into different regions, eliminating electrical leakage risk while maintaining housing compactness through optimized internal arrangement.

Inventive Principle:
Principle #1Segmentation

3Device complexity

If two wires enter from the same side, then the housing structure is simpler, but the connection process becomes cumbersome and electrical leakage risk increases

Engineering Contradiction:
Improvehousing structureVSAvoidconnection process
Core Design Contradiction:
Device complexityVSEase of manufacture

Solution Approach 1:

The patent uses dimensional distribution by having wires enter from opposite sides of the housing, which simplifies the connection process through natural routing while maintaining housing structural simplicity. The opposite-side entry configuration reduces wire congestion and makes manufacturing more straightforward.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

A heating device for a vehicle is described. The heating device includes a heater core and a housing assembly. The housing assembly includes a housing configured with a protruded portion, a first terminal, and a second terminal. The first terminal is configured on the protruded portion of the housing and adapted to be connected with a first bus bar. The second terminal is configured on a first end of the housing and adapted to be connected with a second bus bar. The first bus bar and the second bus bar are connected to the heater core to provide an electrical connectivity to the heater core. The first terminal and the second terminal are laterally offset to each other, and are at least partially on opposite sides of a reference line coinciding with an edge of a printed circuit board received in the housing.
