Overhead frame corners for motion picture and still photography
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Overhead frame corners with perpendicular centerline orientations of T-handle bolts and set screws increase storage space requirements and create protrusions that snag other frames, making bundling and storage inefficient and unstable.
Innovation Solution
Designing secondary fasteners that are positioned within the distal rectangular periphery of overhead frame components, allowing for secure, positionally stable bundling in the alpha orientation without protrusions, reducing storage space and eliminating the need for temporary securing materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If T-handle bolts and set screws are oriented perpendicular to the frame plane, then the fastening function is achieved, but the storage width increases and protrusions are created that snag other frames
Solution Approach 1:
The patent applies local quality by orienting fasteners differently in different locations. Primary fasteners (set screws and T-handle bolts) are oriented perpendicular to the frame plane for secure fastening, while secondary fasteners are oriented parallel to the frame plane to minimize storage width and eliminate protrusions. This localized differentiation resolves the contradiction between fastening effectiveness and storage efficiency.
2Adaptability or versatility
If corners and ears are completely removed for full disassembly, then storage flexibility is improved, but assembly time and complexity increase
Solution Approach 1:
The patent applies preliminary action by pre-attaching secondary fasteners to the corners during manufacturing. These pre-positioned secondary fasteners remain attached during minimal disassembly and automatically secure the frame components in the correct alpha orientation during reassembly, eliminating the need for time-consuming manual alignment and securing operations.
3Stability of the object's composition
If secondary fasteners are added to secure components in alpha orientation, then storage stability is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the fastening system into two distinct functional segments: primary fasteners (set screws and T-handle bolts) that secure components to the frame, and secondary fasteners that secure frame components to each other in the correct storage orientation. This segmentation allows each fastener type to be optimized for its specific function while maintaining overall system manageability.

AI summary
Improved corners for overhead frames having primary and secondary fasteners that are located within the distal rectangular periphery of alpha oriented overhead frame components so that the width of bundled overhead frames is reduced; protrusions leading to snagging are eliminated; and the preferred, industry-wide, disassembled frame orientation is maintained.
