Truss Hinge Angular Variability and Size Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Trusses in stage lighting applications lack flexibility in connecting and configuring different parts to accommodate varying angles and sizes, limiting their adaptability and functionality.
Innovation Solution
A truss hinge system that allows hinging between truss parts in two opposite directions, utilizing adjustable spreaders and spigot connections, enabling configuration of trusses at different angles and sizes by allowing movement and adjustment through the use of pins and spreader bars.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional rigid truss connections are used, then structural stability is maintained, but flexibility and adaptability in configuring different angles and sizes are lost
Solution Approach 1:
The patent applies the dynamics principle by replacing rigid fixed connections with hinged connections that allow movement and angular adjustment. The hinge assembly includes a first hinge part connected to the first truss part, a second hinge part connected to the second truss part, and a spreader bar connecting the two hinge parts. This configuration enables the truss parts to pivot relative to each other, providing dynamic adaptability for different angles and sizes while maintaining structural integrity through the constrained hinge mechanism.
2Adaptability or versatility
If fixed-angle truss connections are used, then manufacturing simplicity is maintained, but configurability for varying stage lighting requirements is limited
Solution Approach 1:
The patent applies segmentation by dividing the connection mechanism into distinct modular components: a first hinge part, a second hinge part, and a spreader bar. Each component has a specific function - the hinge parts provide rotational joints, the spreader bar maintains spacing and provides structural support. This segmented design allows for angular adjustment and reconfiguration while keeping each individual component relatively simple in manufacture, resolving the contradiction between adaptability and complexity.
