Solution Overview

Problem

Existing cavity wall installation boxes face challenges in handling and stability when installed close together, particularly in maintaining mechanical stability between holes and ensuring precise positioning, which can lead to misalignment or damage during installation.

Innovation Solution

A cavity wall installation box with a flexible material heel area that can be pressed into the installation space, allowing for a tilting movement during installation and ensuring the receiving space is positioned behind the planking, along with a collar for secure fastening and airtight sealing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If two cavity wall boxes are arranged close together at standard distance, then the installation space is efficiently utilized, but the mechanical stability of the planking bridge between holes deteriorates

Engineering Contradiction:
Improveinstallation efficiencyVSAvoidmechanical stability of planking
Core Design Contradiction:
ProductivityVSStability of the object's composition

Solution Approach 1:

The heel area of the installation box is designed with flexible material that can be pressed into the installation space, allowing the box to adapt to the planking structure without requiring rigid support between holes

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The installation box allows tilting movement during installation through its flexible heel area, enabling dynamic adaptation to the installation space rather than requiring fixed rigid positioning

Inventive Principle:
Principle #15Dynamics

2Productivity

If two cavity wall boxes are arranged close together, then the installation density is improved, but the positioning precision deteriorates due to difficulty in maintaining exact distance and level

Engineering Contradiction:
Improveinstallation densityVSAvoidpositioning precision
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The flexible heel area enables the installation box to self-adjust during insertion, automatically compensating for minor positioning variations and eliminating the need for precise pre-positioning of holes

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The flexible material allows the heel area to change its physical state during installation, transitioning from a compressed state during insertion to a restored state in the final position, facilitating easier positioning

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If the heel area is made entirely of flexible material, then the ease of insertion is improved, but the structural strength deteriorates

Engineering Contradiction:
Improveease of insertionVSAvoidstructural strength
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

Only the heel area of the installation box is made of flexible material, while the rest of the box body maintains rigid structure, providing localized flexibility for insertion without compromising overall structural strength

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The installation box combines flexible material in the heel area with rigid materials in the main body, creating a composite structure that exhibits both flexibility for insertion and strength for load-bearing

Inventive Principle:
Principle #40Composite materials
