Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing HVAC systems face challenges in maximizing available space for filter replacement and maintenance activities, leading to packaging constraints and difficulties in servicing components like heat exchangers.
Innovation Solution
A housing assembly with a casing and removable cover forming a filter slot for a cuboid filter, allowing airflow guidance and enabling easy filter replacement, and facilitating the movement of heat exchangers during servicing by freeing up space when the cover is removed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If HVAC systems are designed to maximize space utilization, then packaging efficiency is improved, but access to components for maintenance and servicing becomes difficult
Solution Approach 1:
The housing is divided into a fixed casing and a removable cover that can be detached to provide access to the filter slot and heat exchanger. This segmentation allows the system to maintain compact packaging when the cover is attached while enabling easy maintenance when the cover is removed.
Solution Approach 2:
The removable cover transitions between an attached state (providing compact packaging) and a detached state (providing access for maintenance). This dynamic configuration allows the system to adapt between space-efficient operation and serviceability as needed.
2Object-affected harmful factors
If filters are placed within the airflow in the air conduit, then particle removal is improved, but filter replacement becomes complex due to packaging constraints
Solution Approach 1:
The filter is housed in a dedicated filter slot that is accessible through the removable cover. This segmentation allows the filter to be easily removed and replaced by simply detaching the cover, without requiring disassembly of the entire HVAC system or complex manipulation within tight spaces.
3Volume of moving object
If heat exchangers are positioned within the housing assembly, then space efficiency is improved, but removal and servicing of heat exchangers becomes difficult
Solution Approach 1:
The removable cover provides access to both the filter slot and the heat exchanger. This segmentation allows technicians to service the heat exchanger by simply removing the cover, without requiring disassembly of the entire housing assembly, thereby maintaining space efficiency while enabling easy servicing.
4Device complexity
If the housing assembly maintains a compact structure, then packaging constraints are satisfied, but maintenance activities require complex disassembly
Solution Approach 1:
The removable cover is designed as a separate, easily detachable component that provides access to maintenance areas. This segmentation allows quick access to the filter and heat exchanger without requiring complex disassembly of the compact housing structure, thereby reducing maintenance time while preserving packaging efficiency.
Solution Approach 2:
The removable cover enables the housing assembly to transition between a compact closed state (satisfying packaging constraints) and an open access state (enabling quick maintenance). This dynamic design reduces the time required for maintenance activities compared to fixed structures requiring complex disassembly.

AI summary
A housing assembly for an HVAC system, including: a casing with an air inlet and an air outlet, forming a first portion of an air conduit between the air inlet and the air outlet, the air conduit being configured to guide airflow between the air inlet and the air outlet; a removable cover, attached to the casing and forming a second portion of the air conduit. The casing and the removable cover form a filter slot with a filter volume, configured to receive a filter of complementary shape, the filter slot including four sidewalls for constraining the filter, an inlet aperture and an outlet aperture for allowing the airflow between the air inlet and the air outlet. The air conduit includes a guidance wall neighboring at least one of the filter slot sidewalls, the second portion of the air conduit including a part of the guidance wall.
