Solution Overview

Problem

Existing wall-mounted connection box units lack flexibility and ease of use in terms of adjustable axial height and accessibility for fixing the functional surface body to the base section, which complicates installation and maintenance, especially when already mounted on a wall.

Innovation Solution

A rotatable connecting body with an actuation interface located on the functional surface body, allowing for tool-free adjustment between release and fixing positions, and a sleeve element extending through the base section for flexible positioning of the functional surface body relative to the base section, enabling easy axial adjustment and fixing either in front of or behind the base section.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the functional surface body is fixed to the base section at a specific axial height, then the connection box unit can be mounted on a wall, but the axial height cannot be adjusted after installation

Engineering Contradiction:
Improveadjustability of axial heightVSAvoidcomplexity of connection device
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The connection device transitions from a static fixed-position design to a dynamic adjustable design. The connecting body can be moved axially along the sleeve element and locked at different positions, allowing the functional surface body to be positioned at various axial heights relative to the base section, thus enabling adaptability while maintaining manageable complexity through a straightforward mechanical adjustment mechanism.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the connection device requires tools for adjustment, then the fixing can be secure, but the adjustment process becomes complicated and time-consuming

Engineering Contradiction:
Improveease of adjustmentVSAvoidsecurity of fixing
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The connecting body incorporates an actuating interface that enables tool-free adjustment by the user. The design allows manual operation to move the connecting body between release and fixing positions, eliminating the need for external tools while maintaining secure fixing through the engagement of the connecting body with the connection structure at the desired axial position.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If the actuation interface is located on the base section, then the connecting mechanism can be simple, but the interface is inaccessible after wall installation

Engineering Contradiction:
Improveaccessibility of actuation interfaceVSAvoidcomplexity of connection device
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The actuating interface is repositioned from the base section to the functional surface body, changing its spatial location to a more accessible dimension. This allows users to reach and operate the interface after the connection box unit is installed on a wall, as the functional surface body extends toward the wall surface, making the interface accessible from the front rather than requiring access from the rear base section.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
