Solution Overview

Problem

Existing mounting boxes of the second type are inflexible and cannot adapt to varying spaces between inner and outer walls, limiting their applicability in different installation environments.

Innovation Solution

The mounting box features an adjustable axial length, achieved through a modular design with a bottom and top part that can be connected in various configurations, allowing the axial length to be varied between maximum and minimum settings, and includes pre-prepared points for cable and tube lead-ins that move further away in the extended state, maximizing internal space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the mounting box has a fixed axial length, then the structure is simple and manufacturing is easy, but it cannot adapt to varying spaces between inner and outer walls

Engineering Contradiction:
Improveadaptability to varying wall spacesVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mounting box is divided into two separate parts: a bottom part and a top part. These parts can be connected in different configurations to achieve varying axial lengths, allowing adaptation to different wall spaces while maintaining relatively simple individual component structures

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mounting box transitions from a fixed-length structure to an adjustable-length structure. The bottom and top parts can be positioned at different axial distances from each other, enabling dynamic adjustment of the overall axial length to match varying installation requirements

Inventive Principle:
Principle #15Dynamics

2Volume of moving object

If the mounting box axial length is extended to maximize internal space, then more mounting work can be performed inside, but the distance from the wall increases reducing accessibility

Engineering Contradiction:
Improveinternal mounting space volumeVSAvoidaccessibility to mounting space
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

By separating the mounting box into bottom and top parts, the internal volume can be extended axially while maintaining a compact overall profile. The segmented structure allows the mounting space to be distributed between the two parts, providing both capacity and accessibility

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If the mounting box is designed for maximum adaptability with adjustable length, then it can fit various installation conditions, but the manufacturing and assembly process becomes more complex

Engineering Contradiction:
Improveadaptability to installation conditionsVSAvoidmanufacturing and assembly ease
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The mounting box is segmented into standardized bottom and top parts that can be manufactured separately using conventional processes. These modular components are designed to connect through simple, standardized interfaces, maintaining ease of manufacture while achieving adaptability through configurable assembly

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The bottom and top parts are designed as universal components that can be used in multiple configurations. The same basic parts can accommodate different axial length requirements, reducing the need for multiple specialized components and simplifying the manufacturing portfolio

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The mounting box (100) comprises a longitudinal centre axis (X-X), a bottom part (10) and a top part (20). The top part (20) is formed of a tubular body portion (21) with a first end (21A), said first end (21A) being provided with radially outwardly from the body portion (21) extending flange means (22). The bottom part (10) is adapted to be fitted at least partly into the top part (20) so that an opening (O1) is formed through the body portion (21) into a mounting space (M1) formed in the interior of the mounting box (100). The bottom part (10) and the top part (20) are connected through first connection means (50) positioned in connection with the bottom part (20) and second connection means (60) positioned in connection with the top part (20) so that an axial (X-X) position of the bottom part (10) in relation to the top part (20) can be varied in order to vary an axial (X-X) length of the mounting box (100) between a maximum axial length (L1) and a minimum axial length (L2).
