Electrical housing for heating, ventilation, and/or air conditioning (HVAC) system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional HVAC systems require separate housing areas for high voltage and low voltage electrical components, leading to increased manufacturing costs and reduced space efficiency due to the need for separate compartments and larger physical footprints.
Innovation Solution
The HVAC system incorporates a housing design where high voltage components are positioned offset relative to low voltage components, forming an air gap, with a movable panel allowing access to both sets of components without increasing the system's length or width, thereby reducing manufacturing costs and improving space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate housing areas are used for high voltage and low voltage electrical components, then safety and accessibility are improved, but manufacturing cost and space utilization deteriorate
Solution Approach 1:
The electrical components are segmented into high voltage and low voltage groups, with each group positioned in a distinct spatial zone within the housing. The high voltage components are mounted on the base wall while low voltage components are mounted on the movable panel, creating functional segmentation without requiring separate housing sections.
Solution Approach 2:
The patent utilizes the third dimension (depth) by offsetting components along the longitudinal axis of the housing. High voltage components are positioned at a first longitudinal position while low voltage components are positioned at a second longitudinal position, allowing both components to coexist in the same transverse plane without interfering with each other.
2Reliability
If separate housing areas are used for high voltage and low voltage electrical components, then safety is improved, but space efficiency deteriorates
Solution Approach 1:
The patent merges the housing spaces for high voltage and low voltage components into a single integrated housing structure. Both component types are accommodated within the same housing volume by utilizing different longitudinal positions and the movable panel mechanism, eliminating the need for separate housing sections.
Solution Approach 2:
The patent introduces a movable panel that can transition between closed and open configurations. When closed, the panel maintains safety separation by positioning low voltage components away from high voltage components. When opened, it provides access to both component types, dynamically adapting the spatial relationship based on operational requirements.
3Reliability
If components are positioned offset to form air gap, then safety separation is improved, but manufacturing complexity increases
Solution Approach 1:
The movable panel serves multiple functions: it provides structural support for low voltage components, creates the required air gap for safety separation, enables access to both high and low voltage components when opened, and maintains the closed configuration for safety when not in use. This multi-functionality reduces the need for additional separate components.

AI summary
A heating, ventilation, and/or air conditioning (HVAC) unit includes a housing having a base wall, a first electrical component coupled to the base wall, a panel movably coupled to the housing and configured to transition between a closed configuration that defines an air gap between the panel and the base wall and that blocks access to the first electrical component and an open configuration that enables access to the first electrical component, and a second electrical component coupled to the panel. The second electrical component is disposed on a side of the panel opposite the air gap in the closed configuration of the panel.
