Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The process of setting trusses in construction is time-consuming, costly, and hazardous due to the need for multiple workers to lift and guide heavy trusses, which increases the risk of accidents and rental costs for cranes.
Innovation Solution
A truss setting bracket with an elongated body, cradles, a pivotable catch guide, and a locking arm that allows for secure positioning and lifting of trusses, reducing the number of workers required and enhancing safety by facilitating easier and faster truss placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple construction workers coordinate to lift and guide trusses manually, then the trusses can be positioned accurately, but the process becomes time-consuming and costly
Solution Approach 1:
The patent introduces a bracket as an intermediary device that attaches to the truss and provides engagement points for lifting equipment. This mediator enables mechanical assistance in positioning the truss, reducing the time and labor required while maintaining positioning accuracy through the bracket's guided engagement features.
Solution Approach 2:
The bracket is divided into multiple functional components including engagement arms, positioning features, and attachment mechanisms. This segmentation allows each component to perform a specific function in the positioning process, improving overall efficiency while maintaining precision through coordinated action of individual elements.
2Reliability
If multiple construction workers are deployed to set trusses safely, then the trusses can be secured properly, but the risk of construction accidents increases
Solution Approach 1:
The bracket incorporates self-aligning and self-securing features that enable the truss to be positioned and secured with minimal manual intervention. The design includes automatic engagement mechanisms and positioning guides that reduce the need for workers to be in hazardous positions, thereby maintaining reliability while reducing safety risks.
Solution Approach 2:
The bracket serves as an intermediary that handles the heavy lifting and positioning tasks mechanically, reducing the need for workers to manually manipulate heavy trusses. This mediator device performs the dangerous functions while workers supervise from safer positions, maintaining securing reliability while minimizing worker exposure to hazards.
3Force
If cranes are rented on an hour-by-hour basis for truss setting, then heavy trusses can be lifted efficiently, but the cost increases with the time spent setting each truss
Solution Approach 1:
The bracket is pre-attached to the truss before lifting, with all positioning and engagement features prepared in advance. This preliminary preparation enables the crane to lift and position the truss more quickly without requiring time-consuming manual adjustments during the lifting operation, thereby reducing crane rental time while maintaining full lifting capability.
Solution Approach 2:
The bracket replaces manual mechanical positioning operations with a pre-configured mechanical lifting interface. By substituting manual adjustment mechanisms with a pre-engineered bracket design, the lifting process becomes faster and more efficient, reducing crane operation time while preserving the necessary lifting force.
