Removable HVAC Controller Battery Tray for Easy Battery Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
HVAC controllers require battery replacement, which is inconvenient due to the need for dismantling and reassembly, and batteries occupy significant mounting space.
Innovation Solution
A removable battery tray system that allows users to easily insert or replace batteries within the HVAC controller housing, reducing the need for extensive disassembly and providing a compact solution for battery management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If batteries are mounted directly within the controller housing, then battery retention and power supply function are ensured, but user access for battery replacement becomes difficult requiring dismantling and reassembly
Solution Approach 1:
The battery compartment is segmented from the main controller housing as a separate removable tray. This allows the battery section to be independently accessed, removed, and replaced without dismantling the entire controller assembly, thus improving ease of operation while maintaining secure battery retention.
Solution Approach 2:
The battery and its mounting structure are extracted from the integrated controller housing and placed in a separate removable tray. This extraction allows users to access and replace batteries by simply removing the tray from an aperture in the housing, eliminating the need to disassemble the controller and reducing operational complexity.
2Ease of operation
If batteries are mounted within the controller housing, then power supply function is maintained, but significant mounting space is required within the controller
Solution Approach 1:
The battery mounting function is extracted from the main controller housing and placed in a separate removable tray that inserts into an aperture. This allows the battery compartment to occupy external or peripheral space rather than consuming valuable internal controller space, while still providing easy access through simple tray removal.
Solution Approach 2:
The battery compartment is moved from a two-dimensional internal mounting plane to a three-dimensional removable tray structure that can be accessed from the front aperture. This dimensional transition allows for more efficient space utilization within the controller housing while maintaining easy battery access.

AI summary
An HVAC controller includes a controller housing having an aperture and a battery tray removably disposed within the aperture. The battery tray can include an outer wall and a beam element fixed relative to the outer wall and extending away from the outer wall. The beam element can have a free end and an end element disposed on or adjacent to the free end.
