One-Piece Spring and Trolley Bracket for Garage Door Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of trolley brackets in movable barrier systems is burdensome and intimidating due to their proximity to torsion systems, often requiring professional assistance and separate installation from spring brackets, posing risks and inefficiencies.
Innovation Solution
A one-piece spring and trolley bracket is introduced, formed from a single piece of material, integrating a spring mount and trolley mount with a spine portion, allowing secure fixation to a structure and accommodating various torsion spring and trolley track dimensions, simplifying installation and reducing component count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate spring bracket and trolley bracket are used, then each component can be optimized independently, but installation complexity increases and installation time increases
Solution Approach 1:
The patent combines the spring bracket and trolley bracket into a single integrated bracket assembly that includes both a spring mount portion and a trolley mount portion. This merging eliminates the need for separate installation of two brackets, reducing installation complexity and time while maintaining the functional optimization of both components through dedicated mounting areas for springs and trolleys within the unified structure.
Solution Approach 2:
The integrated bracket serves multiple functions simultaneously: it provides mounting for torsion springs, mounting for trolley tracks, and structural support for the barrier system. The universal design allows a single component to fulfill the roles previously requiring separate brackets, simplifying the overall system while maintaining adaptability for different spring and trolley configurations.
2Reliability
If trolley bracket is installed separately near torsion system, then proper mounting is possible, but installation becomes intimidating and requires professional assistance
Solution Approach 1:
By integrating the spring bracket and trolley bracket into one piece, the patent eliminates the intimidating aspect of installing separate brackets in close proximity to high-load torsion systems. The unified design allows installers to work with a single component that has pre-defined mounting zones, reducing the perceived complexity and risk while maintaining reliable mounting capabilities through engineered attachment points.
3Adaptability or versatility
If multiple separate brackets are used, then each can be optimized for its specific function, but manufacturing and inventory costs increase
Solution Approach 1:
The patent reduces the quantity of components by merging multiple brackets into one integrated bracket. This single component replaces what would otherwise require separate spring brackets and trolley brackets, reducing manufacturing complexity, inventory requirements, and assembly steps while maintaining functional optimization through dedicated mounting sections for different components within the unified structure.

AI summary
A one-piece bracket is usable to secure a garage door system. The bracket includes a spring mount configured to secure a torsion spring of a movable barrier system; a trolley mount configured to secure a trolley track of a movable barrier system; and a spine portion extending between and connecting the spring mount to the trolley mount in a fixed relationship. At least one of the spring mount, the trolley mount, and the spine portion includes a mounting portion for fixation of the bracket to a structure.
