Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional truss brackets lack adjustability, leading to inefficiencies and increased costs due to the need for custom design and custom welding to accommodate variations in truss member orientations.
Innovation Solution
A universal and adjustable truss bracket design featuring a base plate with rotatable arms, allowing for precise alignment and secure fastening to truss members, thereby accommodating various truss designs and orientations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional preformed truss brackets are used, then manufacturing is simple, but they lack adjustability and require custom design/welding to accommodate variations in truss member orientations
Solution Approach 1:
The bracket incorporates rotatable arms that can be adjusted during installation to match the specific orientation of truss members. The arms rotate about fasteners to align with members in the direction of extension, providing dynamic adaptability without requiring custom-designed brackets for each orientation.
Solution Approach 2:
The bracket design uses a universal base plate with multiple arms that can be rotated to accommodate various truss member orientations. This single bracket type serves multiple functions by adapting to different angular configurations, eliminating the need for custom-designed brackets for each orientation.
2Productivity
If conventional preformed brackets are forced into skewed positions to match truss orientations, then installation is faster, but the effectiveness and strength of the brackets are altered
Solution Approach 1:
The rotatable arms allow the bracket to be installed in a standardized position and then adjusted during installation to match the specific truss member orientation. This ensures both fast installation and maintained effectiveness, as the arms can be rotated to the correct angle without forcing the bracket into a skewed position.
3Manufacturing precision
If custom-designed brackets are created to meet variations in truss member orientations, then fit and strength are optimized, but the process is time-consuming and expensive
Solution Approach 1:
Instead of manufacturing custom brackets for each orientation, the design uses adjustable arms that can be rotated during installation to achieve the precise fit required. This eliminates the time-consuming custom design and welding process while maintaining the necessary precision for each specific orientation.
4Ease of manufacture
If conventional brackets are used without adjustability, then manufacturing is straightforward, but custom welding and measuring are required to accommodate orientation variations
Solution Approach 1:
The bracket maintains simple manufacturing through a standardized base plate design while adding adjustability through rotatable arms. This allows the bracket to be manufactured once and then adapted during installation, eliminating the need for custom welding and measuring for each orientation variation.

AI summary
A bracket includes a base plate having a first side and a second side opposite the first side of the base plate. The bracket includes a shelf having a first side extending from the first side of the base plate and a second side opposite the first side of the shelf. The bracket includes one or more arms disposed adjacent to the first side of the shelf. The one or more arms are rotatably mounted to the shelf.
