Screen Roller Mounting Accessory for Concealed Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern house-building trends, such as minimalist architecture and increased wall thickness for insulation, make it difficult to access the protective casing of screen devices for maintenance, as traditional openings are either visible or require additional space.
Innovation Solution
A screen device with a guide element that allows the screen roller to be moved into and out of the protective casing via a longitudinal movement, eliminating the need for visible openings and allowing for concealed access, using a mounting accessory that positions and secures the guide element, and includes stops to prevent unwanted movement, enabling easy assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional openings are provided on inner or outer walls for accessing the protective casing, then maintenance access is enabled, but the aesthetic appearance is compromised due to visible openings
Solution Approach 1:
The invention extracts the access opening from the wall structure and relocates it to the protective casing itself. The opening is now provided in the protective casing at a location accessible from the room side, allowing maintenance personnel to access the screen roller and other components without creating visible openings in the wall or window frame, thus preserving the aesthetic appearance while enabling maintenance access.
2Loss of energy
If the protective casing is built into thick walls for insulation, then energy efficiency is improved, but access to the casing for maintenance becomes difficult
Solution Approach 1:
The invention introduces an intermediary access mechanism - a opening in the protective casing with a cover that can be opened from the room side. This intermediary structure allows maintenance personnel to access the interior of the protective casing and the screen roller without needing to access the wall from the exterior, thus maintaining the thick wall insulation while enabling easy maintenance access from the interior.
3Reliability
If the screen roller is mounted to require transverse movement for removal, then secure mounting is achieved, but the device depth increases
Solution Approach 1:
The invention inverts the traditional mounting approach by having the screen roller move in the longitudinal direction (parallel to the wall) rather than requiring transverse movement (perpendicular to the wall). The guide element guides the screen roller along the longitudinal direction, allowing the screen roller to be moved out of the protective casing through a longitudinal movement, thus reducing the required device depth while maintaining secure mounting through the guide element and mounting accessory.
