Cable Holder Elevates Projector Wiring Above Floor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projection systems face issues with cables contacting the floor or installation surface, leading to viewer obstruction and potential electrical leakage in moist environments, particularly when used outdoors or in water fields.
Innovation Solution
A projection system with a support apparatus that includes a cable holder positioned above the installation surface, ensuring the cable is kept above the floor or installation surface, using a cable holder and support section configuration that prevents contact and includes a rotatable rotor and extending sections to securely manage the cable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cable is laid on the ground to connect the projector, then the cable can be easily routed and connected, but the cable may contact the moisture on the ground causing electrical leakage or obstruct viewers
Solution Approach 1:
The patent transitions the cable from a horizontal ground-level layout to a vertical suspension layout. The cable is routed upward from the projector along the installation surface and suspended in the air space above the screen, changing the spatial dimension from 2D ground plane to 3D vertical space, thereby eliminating contact with ground moisture while maintaining connectivity
Solution Approach 2:
The patent introduces intermediate components including a cable holder attached to the installation surface and a cable guide structure. These intermediaries support and guide the cable through the air space, mediating between the projector and the screen area without the cable touching the ground, thus ensuring electrical safety while maintaining ease of installation
2Ease of manufacture
If the cable is laid on the ground, then cable installation is simple, but viewers may be caught by the cable running on the ground
Solution Approach 1:
The cable is relocated from the horizontal ground plane to the vertical air space above the screen. By routing the cable upward along the installation surface and suspending it vertically, the patent removes the cable from the viewer's ground-level activity zone, eliminating the tripping hazard while keeping installation straightforward through the use of wall-mounted cable holders and guides
3Device complexity
If the cable holder is positioned close to the installation surface, then the structure is compact, but the cable may still contact the installation surface or floor
Solution Approach 1:
The cable holder is designed to extend vertically from the installation surface, creating a vertical clearance dimension. The cable is positioned in this vertical air gap between the holder and the screen area, ensuring sufficient clearance from both the installation surface and the floor, while the holder itself remains compactly attached to the wall or ceiling structure

AI summary
A projection system according to the present disclosure includes a first projector that projects image light onto a screen and a support apparatus. In the projection system, the support apparatus includes a cable holder that holds a cable having one end coupled to the first projector, and a support section that positions the cable holder with respect to an installation surface at which the first projector is provided, and in the upward vertical direction, the distance from the installation surface to the cable holder is greater than the distance from the installation surface to the top surface of the first projector.
