Wall Plate Flexible Screen Cable Passage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall plates with protrusions obstruct the mounting of communication devices when extending communication cables through walls, as the protrusions create obstacles and may have small openings that hinder cable passage.
Innovation Solution
A wall plate structure with a flexible, flat screen that covers the opening, featuring star-cut openings allowing cable passage without protrusions, and an internal support frame for secure mounting, accommodating various cable thicknesses and providing a visual guide for hole placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a protruding nose is added to the wall plate to cover the opening, then the visual appearance is improved, but the mounting of communication devices is obstructed
Solution Approach 1:
The invention removes the protruding nose element from the wall plate design. Instead of having a nose protrude from the wall surface, the screen is made substantially flat and mounts flush against the wall, eliminating the obstruction while maintaining the cable passage function through openings in the screen.
Solution Approach 2:
Instead of having the wall plate protrude outward to cover the opening (traditional approach), the invention inverts the approach by making the screen flat and having it mount flush against the wall surface, with the cable openings providing the coverage function rather than a protruding structure.
2Length of stationary object
If the nose is made shallow to reduce protrusion, then the obstacle to device mounting is reduced, but the opening size through the nose becomes smaller, hindering cable passage
Solution Approach 1:
The invention eliminates the nose structure entirely, replacing it with a flat screen that has cable openings directly formed in it. This removes the trade-off between protrusion depth and opening size, as the screen provides both functions simultaneously - covering the wall plate opening while maintaining adequate cable passage areas.
Solution Approach 2:
The invention merges the functions of the nose (covering the opening) and the cable passage opening into a single integrated screen structure. The screen simultaneously provides visual coverage and cable access without requiring a protruding nose, combining multiple functions into one flat element.
3Stability of the object's composition
If a rigid screen is used to maintain structural integrity, then the screen stability is improved, but the cable passage through the screen becomes more difficult
Solution Approach 1:
The invention makes the screen flexible rather than rigid, allowing it to dynamically deform when cables are inserted. The flexible screen can be pushed inward to accommodate cables and then returns to its original position, providing both stability when installed and ease of cable installation.
Solution Approach 2:
The invention uses a flexible screen made of a thin, pliable material that can be pushed inward to allow cable passage and then returns to its original shape. This flexible membrane approach allows the screen to maintain its covering function while easily accommodating cable insertion without requiring rigid structures with large openings.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The flexible screen allows seamless cable passage without obstructing device mounting, securely fastens to the wall, and adjusts to different cable sizes, while the support frame ensures stability and easy installation.
Implementation Method 1
The screen of the wall plate structure is formed of flexible material and the flexible material defines at least one flexible opening therethrough

AI summary
The wall plate structure (10) includes a wall plate (16) that has a rectangular opening (50) therein. A flat, flexible screen (18) is mounted to the back surface (46) of the wall plate and closes the opening (50). Openings (66, 67 and 68) are formed in the screen for the passage therethrough of communication cable (74). The wall plate structure is substantially flat to facilitate the mounting of communication equipment in flat abutment with the wall surface.
