Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting brackets for fabricated steel trusses are complex and require sophisticated installation procedures, making them time-consuming and difficult to install, especially in retail and warehouse applications where visibility and ease of relocation are important.
Innovation Solution
A simplified mounting bracket design featuring a housing with a planar mount surface, tubular collar, and a suspending member with a threaded shank and hook portion that securely engages the lower chord of a steel truss, allowing for easy installation and relocation of security devices like surveillance cameras, with integrated cable passage ports for electrical conduit and cabling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a multi-component mounting bracket structure is used to securely mount equipment to the truss, then the mounting reliability is improved, but the device complexity and installation difficulty increase
Solution Approach 1:
The patent combines multiple mounting functions into a single integrated bracket assembly that includes the mounting plate, suspending member, and cable management features as one unified component, eliminating the need for separate multi-component structures while maintaining secure mounting reliability
Solution Approach 2:
The mounting bracket is designed with multi-functionality to perform multiple tasks simultaneously: securing equipment to the truss, providing cable passage ports for electrical conductors, and enabling easy installation and relocation, thereby reducing overall system complexity while improving reliability
2Reliability
If a multi-component mounting bracket structure is used to securely mount equipment to the truss, then the mounting reliability is improved, but the installation time and complexity increase
Solution Approach 1:
The mounting bracket is pre-assembled as an integrated unit with all necessary components (mounting plate, suspending member, cable ports) prepared in advance, allowing for rapid installation by simply positioning and securing the complete assembly to the truss without time-consuming on-site assembly of multiple parts
3Ease of operation
If a simplified mounting bracket design is used to reduce installation time, then the ease of operation is improved, but the mounting reliability may be compromised
Solution Approach 1:
The integrated bracket design combines sufficient structural elements into a single unit that maintains adequate mounting reliability through its unified construction, while the simplification of eliminating multiple separate components directly improves ease of installation and operation
4Device complexity
If an integrated casting design is used for the housing sections, then the device complexity is reduced, but the manufacturing precision requirements increase
Solution Approach 1:
The patent employs an integral casting design that merges multiple housing sections (first section, tubular collar, arms, center mount area) into a single manufactured component, reducing device complexity by eliminating assembly interfaces while the casting process inherently provides sufficient manufacturing precision for the application

AI summary
The truss mounting bracket simplifies installation of electronic type equipment below fabricated trusses commonly used in warehouse and other buildings. The mounting bracket includes a housing having at one end thereof a structure for connecting with an electrical conduit section. The opposite end of the housing is adapted to allow securement below a fabricated truss. A head portion extends from a center portion of the housing and has a thread connection therewith. The head portion engages the truss and allows the housing to be tightened against the lower surface of the truss. The conduit and the housing allow electrical cables to pass through the conduit and at least partially through the housing.
