Displaceable Sprout for Installation Box Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing installation boxes for hollow walls face challenges when a back support frame part obstructs the passage for the sprout part, making it difficult to mount the box, especially when the frame is close to or overlaps the wall opening.
Innovation Solution
A combination of an installation box and a sprout part that allows the sprout to be positioned either above or below the box's bottom wall, enabling it to be mounted regardless of the frame's location, with a design that includes a displaceable sprout part and a gap-closing mechanism to ensure electrical safety and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the installation box is mounted with a fixed sprout part position, then the mounting process is simple, but the box cannot be mounted when a back support frame part obstructs the passage
Solution Approach 1:
The sprout part is made movable relative to the installation box body, allowing it to be positioned in different locations (first position when frame is remote, second position when frame is close). This dynamic positioning capability enables the system to adapt to different mounting conditions without requiring multiple different box designs.
2Ease of operation
If the sprout part is fixed in position, then the structure is simple, but the tube cannot reach the back side of the front wall board when the frame is close
Solution Approach 1:
The sprout part can be moved between a first position (when no frame obstruction) and a second position (when frame is close to the wall opening). This dynamic adjustment allows the tube to always reach the back side of the front wall board regardless of frame position, simplifying tube installation in various scenarios.
3Adaptability or versatility
If the sprout part is made displaceable to accommodate frame obstruction, then mounting flexibility improves, but the sealing and electrical safety may be compromised
Solution Approach 1:
A sealing element is introduced as an intermediary component between the sprout part and the installation box body. This sealing element ensures that electrical safety and sealing are maintained regardless of the sprout part's position, allowing the system to achieve both mounting flexibility and reliability.
4Adaptability or versatility
If the sprout part is positioned above the bottom wall, then the structure is compact, but it cannot accommodate frames close to the wall opening
Solution Approach 1:
The sprout part is designed to be movable between different positions (above the bottom wall in first position, below the bottom wall in second position). This dynamic configuration allows the system to accommodate frames at various distances from the wall opening while maintaining a relatively compact overall structure.

AI summary
An installation box comprises a bottom wall and a side wall. The bottom wall comprises a bottom wall opening connecting to a side wall opening of the side wall. A sprout part comprises a bottom wall section conforming to the bottom wall opening of the installation box, and a side wall section conforming to the side wall opening of the installation box, and having at least one sprout extending at right angles to the side wall section from a sprout opening in the side wall section. In a first position of the sprout part, the sprout opening thereof is above the bottom wall of the installation box. In the second position of the sprout part, the sprout opening thereof is at least partly below the bottom wall of the installation box.
