Truss System for Video Displays with Overhanging Rigging Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Video display truss systems face stability challenges due to the weight of displays, and existing solutions like ballast create tripping hazards, extend the system's footprint, and complicate maintenance with interfering cables.
Innovation Solution
A truss system comprising a rectangular frame with a rigging plate and slidable attachment mechanisms, allowing for suspension of video displays without ballast, featuring interchangeable rectangular tubes and support feet to manage the center of gravity, and accessible cavities for cable management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If ballast is used to anchor the truss system, then stability is improved, but tripping hazards and extended footprint are created
Solution Approach 1:
The patent removes the ballast component entirely from the truss system, replacing it with an self-supporting structure that achieves stability through its own geometry and support feet rather than external anchoring weights. This extraction eliminates the tripping hazard while maintaining stability.
Solution Approach 2:
Instead of using ballast as a counterweight to stabilize the system, the patent employs support feet that distribute the system's own weight to the ground, creating stability through direct ground contact and geometric distribution of forces rather than through counterbalancing masses.
2Stability of the object's composition
If ballast with tethering cables is used, then stability is improved, but maintenance access is interfered with
Solution Approach 1:
The patent removes both the ballast and tethering cables from the system, replacing them with a self-supporting structure that provides unobstructed access to the video display from the front and sides, eliminating maintenance interference entirely.
3Adaptability or versatility
If conventional truss systems are used, then video display suspension is achieved, but assembly complexity is high
Solution Approach 1:
The truss system is divided into modular components including rectangular tubes, connection nodes, support feet, and rigging plates that can be independently manufactured and assembled. This segmentation simplifies assembly while maintaining the capability to suspend video displays.
Solution Approach 2:
The rectangular tubes and connection nodes are designed as universal components that can be configured for different video display sizes and arrangements. The same basic components serve multiple functions including structural support, cable routing, and display mounting, reducing overall system complexity.
4Stability of the object's composition
If ballast is used to anchor the system, then stability is improved, but system footprint is extended
Solution Approach 1:
The patent replaces external ballast with integrated support feet that are part of the main truss structure. These feet extend downward from the rectangular frame to provide ground contact points, achieving stability within the same footprint as the display area rather than extending beyond it with separate ballast weights.

AI summary
A truss system configured as a rectangular frame and a rigging plate is provided. The rectangular frame comprises an interconnected assembly of rectangular tubes. The rigging plate is removably attached to a top surface of the rectangular frame and includes an overhanging portion that overhangs a front side of the rectangular frame. The overhanging portion includes a plurality of attachment apparatuses for suspending at least one video display from the overhanging portion such that the video display(s) overhangs the front side of the rectangular frame.
