Wall Control Frame Adapting to Cavity Sizes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall control apparatuses are limited in adaptability to different wall box sizes and configurations, often requiring adaptor jigs and not fully covering the access mouth of the cavity, which restricts their installation flexibility and compatibility with various wall types.
Innovation Solution
A wall control apparatus with a modular design featuring a support frame that can be superposed over the wall cavity or wall box, equipped with a central opening for cable passage and reversible connection means, allowing the electronic display device to extend completely outside and cover the access mouth regardless of the box dimensions, with adjustable fixing members to accommodate different standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the control apparatus is fixed to fit inside a specific wall box cavity, then the apparatus structure is simplified, but the adaptability to different wall box sizes and configurations is reduced
Solution Approach 1:
The control apparatus is divided into two main segments: a support frame that interfaces with the wall box cavity and an electronic display device that mounts to the frame. This segmentation allows the support frame to be adapted to different cavity sizes while the electronic device remains standardized, resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The support frame is designed as a universal component that can accommodate multiple wall box configurations through adjustable fixing members. The frame serves multiple functions: structural support, cable management through a central opening, and positioning of the electronic device, thereby achieving adaptability without proportionally increasing overall complexity.
2Area of stationary object
If the apparatus is designed to fully cover the access mouth of the cavity, then the aesthetic appearance is improved, but the device thickness increases
Solution Approach 1:
The electronic display device is positioned in a plane that extends beyond the wall box cavity face, utilizing the external wall surface area. This dimensional transition allows the display to cover the access mouth aesthetically while keeping the portion entering the cavity minimal, thus covering the area without proportionally increasing the thickness into the wall space.
3Area of moving object
If the containment compartment fits inside the wall box, then the installation is simplified, but the screen size is limited
Solution Approach 1:
By separating the support frame (installed in cavity) from the electronic display device (mounted externally), the system allows the screen to extend beyond the cavity boundaries. This segmentation enables larger screen sizes while maintaining relatively simple installation through the reversible connection mechanism between frame and device.
4Adaptability or versatility
If fixed fixing members are used to attach the apparatus to the wall box, then the manufacturing precision is improved, but the adaptability to different wall box standards is reduced
Solution Approach 1:
The fixing members are designed to be adjustable in position along the support frame rather than being fixed at predetermined locations. This dynamic positioning capability allows the same apparatus to accommodate different wall box standards (Italian, German, American) without requiring multiple precision-manufactured variants, thereby achieving adaptability while maintaining reasonable manufacturing tolerances.
