Electrical Box Bracket with Foldable Tabs for Block Walls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of electrical boxes in cinder block walls is inefficient due to the need for two contractors to manage the box's positioning, leading to time and resource wastage, and conventional block brackets lack mounting holes for devices like alarm strobes.
Innovation Solution
An electrical box block bracket with adjustable panels and foldable tabs that can be securely positioned within a cinder block, eliminating the need for manual holding and providing mounting holes for additional devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional block brackets are used without mounting holes, then the bracket structure remains simple, but additional devices like alarm strobes cannot be mounted to the electrical box
Solution Approach 1:
The block bracket is designed with multiple functions: it secures the electrical box to the block wall and provides mounting holes in all four corners for attaching additional devices such as alarm strobes, covers, or other electrical components. This multi-functional design eliminates the need for separate mounting brackets for different devices.
2Reliability
If two contractors are used to hold and install the electrical box, then proper positioning can be achieved, but installation time and labor costs increase significantly
Solution Approach 1:
The electrical box is pre-attached to the block bracket before installation. The bracket includes a pre-formed opening that receives the electrical box, allowing the electrical contractor to secure the box to the bracket in advance. This preliminary attachment eliminates the need for a second contractor to hold the box during installation.
3Ease of operation
If the electrical box is held manually during installation, then positioning can be adjusted, but the box is unstable and may fall into the block wall opening
Solution Approach 1:
The mounting system is divided into separate functional components: the block bracket that interfaces with the block wall, the electrical box that contains the electrical components, and the pre-formed opening that receives the box. This segmentation allows each component to be optimized for its specific function while working together as a unified mounting system.

AI summary
An electrical box block bracket can include a face place and rotatable members extending from each of two opposing edges of the face plate. The face plate can also include a aperture providing a passageway through the face plate and sized and shaped to receive a mud ring and/or electrical junction box. Each rotatable member can be rotatable about an axis defined by the intersection between the face plate and the respective rotatable member. Each rotatable member can also include an adjustable tab disposed along the surface of the rotatable member. The adjustable tab can rotate from a first position aligned with the surface of the rotatable member to a second position at an angle to the surface of the rotatable member such that the tab can be folded over at least a portion of an outer wall or rib of a construction block.
