HVAC Controller Side Battery Tray for Easy Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
HVAC controllers face inconvenience due to the need for periodic battery replacement, which requires dismantling and reassembly, and occupy significant mounting space within the device.
Innovation Solution
A side removable battery tray system that allows users to replace batteries without removing the controller from its mounting surface, featuring a pivot point for easy rotation and secure engagement with the controller housing, enabling battery access from the side surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a battery is mounted within the controller housing, then power supply function is provided, but the controller requires significant mounting space and periodic replacement is inconvenient
Solution Approach 1:
The battery compartment is segmented from the main controller housing as a separate removable tray. This segmentation allows the battery to be accessed and replaced independently without dismantling the entire controller, thus improving ease of operation while maintaining a simple overall structure.
Solution Approach 2:
The battery is extracted from the traditional fixed internal mounting and placed in a removable tray that can be taken out from the side of the controller. This extraction enables easy battery replacement by simply removing the tray from the side aperture, eliminating the need to open the controller front or back panels.
2Area of stationary object
If a battery is mounted within the controller housing, then power supply function is provided, but the battery occupies significant mounting space within the device
Solution Approach 1:
Instead of mounting the battery vertically or horizontally within the limited internal space of the controller housing, the battery is mounted in a tray that extends outward from the side of the controller. This dimensional change utilizes the side aperture and external space, freeing up valuable internal controller space while maintaining reliable power supply through proper electrical contacts.
3Ease of operation
If the battery tray is made removable with pivot point, then battery replacement becomes easy, but the device structure becomes more complex
Solution Approach 1:
The battery tray is made dynamic with a pivot point that allows it to rotate between a retracted position (flush with controller side) and an extended position (protruding from controller). This dynamic mechanism enables easy battery access by simply rotating the tray outward, while the pivot point design keeps the mechanism simple and reliable without requiring complex locking or actuation systems.
