Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Welded structures used in multimedia systems for the performance industry are heavy, require skilled fabricators, and are difficult to repair or replace, with joints susceptible to damage from environmental stressors and physical strain during touring.
Innovation Solution
A modular video support structure using pinned connections between support members, allowing for easy assembly and disassembly with minimal tools and skill, and providing resistance to environmental stressors through pinnable joints secured by pins.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If welded structures are used to support video displays, then joint strength and structural stability are improved, but weight increases and fabrication complexity increases
Solution Approach 1:
The support structure is divided into modular components (vertical support members, cross members, braces) that can be independently manufactured and assembled. Each component features standardized pinnable joints with openings that accept pins, allowing the structure to be segmented into manageable sections that are easier to handle and assemble while maintaining overall structural integrity
Solution Approach 2:
The patent replaces the welding process (thermal/mechanical fusion) with a mechanical pinning system. Pins inserted through aligned openings in perpendicular members create secure connections through friction and geometric interlocking, eliminating the need for welding equipment and skilled welders while reducing joint weight
2Strength
If welded structures are used to support video displays, then joint strength is improved, but ease of manufacture deteriorates
Solution Approach 1:
The structure is segmented into pre-fabricated modular components with standardized pinnable joints. Each component can be manufactured independently using simpler processes (drilling openings vs. welding), then assembled by inserting pins through aligned openings, dramatically simplifying the manufacturing and assembly process while maintaining joint strength
Solution Approach 2:
The patent employs simple, inexpensive pin connectors instead of complex welded joints. The pins are basic mechanical fasteners that can be easily replaced if damaged, and the modular components can be disassembled and reconfigured, reducing manufacturing costs and complexity
3Stability of the object's composition
If welded structures are used to support video displays, then structural stability is improved, but ease of repair deteriorates
Solution Approach 1:
The modular segmented design allows any damaged component (vertical support member, cross member, or brace) to be independently removed and replaced. Each component connects via pinnable joints with standardized openings, enabling quick swap-out of damaged parts without affecting the rest of the structure, thereby improving ease of repair while maintaining structural stability
Solution Approach 2:
The patent enables easy discarding of damaged components and recovery of intact ones. Modular components with pinnable joints can be quickly disassembled, allowing damaged parts to be replaced while recovering and reusing sound components in other positions, simplifying maintenance and repair operations
4Ease of operation
If pinned connections are used to support video displays, then ease of assembly is improved, but resistance to environmental stressors deteriorates
Solution Approach 1:
The pinnable joints provide a degree of flexibility and movement capability that allows the structure to dynamically respond to environmental stressors. The pinned connections can accommodate thermal expansion, contraction, and minor misalignments that occur during transportation and assembly, reducing stress concentration while maintaining overall structural reliability
Solution Approach 2:
The modular pinned design inherently provides cushioning against stressors by allowing small movements and adjustments at each joint. This flexibility prevents stress buildup from thermal expansion, contraction, and handling during transportation, protecting the overall structure from damage while maintaining ease of assembly

AI summary
A video support structure for supporting video, a video display system, and a method of securing the support structure are disclosed. The video support structure includes a first support member, a second support member, a portion of the second support member being receivable by a surface or space formed by the first support member, a pinnable joint having an opening in each of the first support member and the second support member, the openings being alignable to receive one or more pins, and the one or more pins, the one or more pins being configured to secure the first support member to the second support member to form at least a portion of the video support structure.
