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

VSEngineering 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

Engineering Contradiction:
Improvemounting flexibilityVSAvoidsprout part configuration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

Inventive Principle:
Principle #15Dynamics

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

Engineering Contradiction:
Improvetube installationVSAvoidsprout part mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

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.

Inventive Principle:
Principle #15Dynamics

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

Engineering Contradiction:
Improvemounting flexibilityVSAvoidelectrical safety and sealing
Core Design Contradiction:
Adaptability or versatilityVSReliability

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.

Inventive Principle:
Principle #24Intermediary (Mediator)

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

Engineering Contradiction:
Improveframe position accommodationVSAvoidinstallation box configuration
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

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.

Inventive Principle:
Principle #15Dynamics

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.
