Low Profile Emergency Battery Driver Enclosure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional emergency power features in lighting systems have a larger cross-section, making them difficult to accommodate within the housing of modern lighting systems, which often have low-profile designs and require minimized space.
Innovation Solution
A low-profile emergency battery-driver enclosure with an interlocking structure that overlaps at non-adjacent corners, optimizing space usage by maintaining uniform external and internal dimensions, reducing the overall size without sacrificing internal volume.

1Volume of moving object
If conventional housing-lid construction methodologies are used, then the emergency driver can be housed within the lighting system, but the cross section becomes larger and difficult to accommodate in low-profile designs
Solution Approach 1:
The housing is divided into a base and a lid that can be separated and reconfigured. The lid is designed to rotate and interlock with the base at non-adjacent corners, allowing the components to be segmented for manufacturing and assembly while forming a compact integrated structure that reduces overall cross-section.
Solution Approach 2:
The lid and base overlap at non-adjacent corners (diagonal corners) rather than adjacent corners, utilizing diagonal spatial arrangement to optimize the footprint. This dimensional reconfiguration reduces the bounding box dimensions while maintaining internal volume, enabling low-profile accommodation.
2Length of stationary object
If the enclosure size is reduced to meet low-profile requirements, then the external dimensions are minimized, but the internal volume for batteries and drivers may be compromised
Solution Approach 1:
By overlapping the lid and base at non-adjacent corners, the design exploits diagonal space utilization to reduce external footprint while preserving internal volume. The interlocking configuration at diagonal corners creates efficient space utilization where the overlapping regions are positioned to minimize external dimensions without encroaching on the internal component space.
Solution Approach 2:
The overlapping regions are localized to specific non-adjacent corners rather than distributed uniformly, allowing the majority of the enclosure to maintain full internal volume. The interlocking tabs and recesses are concentrated at the corners, leaving the central and edge regions available for battery and driver placement.

AI summary
A battery-driver enclosure for a light fixture includes a first member and a second member. The first member and the second member together define the battery-driver enclosure, and the first member and the second member overlap at non-adjacent corners of the enclosure. A method of assembling a battery-driver enclosure includes engaging the first member with the second member to form the battery-driver enclosure and such that the first member and the second member overlap at non-adjacent corners of the battery-driver enclosure.
