Solution Overview

Problem

Existing box assembly systems for closing systems, such as venetian or pleated blinds, are limited by a minimum gap size of 20 mm, making it impossible to install blind components in double panes with smaller gaps, thereby preventing the improvement of these panes.

Innovation Solution

A box for a closing system with a configurable design that includes a support profile and a closing profile, allowing the movement unit to be easily inserted regardless of the gap size, with slots for support elements and a closing mechanism that can be fixed to accommodate rollers and ropes, enabling installation in gaps as small as 20 mm or less.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a traditional box assembly system is used, then the box can be assembled with standard components, but the minimum gap size is limited to 20 mm, making it impossible to install in smaller gaps

Engineering Contradiction:
Improveadaptability to different gap sizesVSAvoidminimum gap size
Core Design Contradiction:
Adaptability or versatilityVSLength of moving object

Solution Approach 1:

The box is divided into modular components: a support profile and a closing profile that can be assembled separately. This segmentation allows the box to be configured in different sizes and shapes, enabling installation in various gap dimensions including those smaller than 20 mm, while maintaining structural integrity through the modular assembly approach.

Inventive Principle:
Principle #1Segmentation

2Length of moving object

If the box size is reduced to fit smaller gaps, then installation in narrow double panes becomes possible, but the movement unit may not fit or function properly

Engineering Contradiction:
Improvebox transverse sizeVSAvoidmovement unit functionality
Core Design Contradiction:
Length of moving objectVSReliability

Solution Approach 1:

The box design incorporates dynamic adjustability through the modular support and closing profile assembly. The profiles can be positioned and configured to create the optimal internal volume for the movement unit regardless of the external box dimensions. This allows the box to be externally compact for small gaps while internally accommodating the full-size movement unit needed for reliable blind operation.

AI summary

A box for a system for opening and closing a communication route between two separate areas, the system including separation means suitable for allowing and preventing, respectively, at least partially, crossing of the route by light, may include: a box body configured to accommodate a movement unit of the system; and support elements for the movement unit. The box body may have a major extension direction. The box body may be defined by support and closing profiles, both extending along the direction. The support profile may define at least one upper, lower, and connecting wall. The closing profile may define a closing wall. The closing profile may be removably fixable to the support profile for closing the box body. When the closing profile is fixed to the support profile, a distance between the closing wall and the connecting wall may be less than or equal to 20 millimeters.
