Solution Overview

Problem

Existing vertically folding wall partitions often interfere with objects or pose a risk of injury as the folding panels move outwardly, due to their folding mechanism.

Innovation Solution

A vertically folding wall partition with pivotally connected panel assemblies and a cable and pulley system that allows sequential folding, starting from the uppermost panels, to minimize interference and ensure safe operation by folding panels high above potential obstacles and occupants.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the wall partition folds with bottom panels moving outwardly, then the partition can be collapsed to a compact position, but the folding panels interfere with objects near the wall and pose injury risk to persons in proximity

Engineering Contradiction:
Improvecollapsed volumeVSAvoidinterference with objects and injury risk
Core Design Contradiction:
Volume of moving objectVSObject-affected harmful factors

Solution Approach 1:

The patent changes the folding dimension from horizontal (bottom panels moving outward) to vertical (panels folding upward). The panel assemblies fold vertically toward the ceiling structure, stacking in an opposed surface-to-surface relationship, which eliminates interference with objects on the floor and reduces injury risk to persons below.

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

Solution Approach 2:

The patent inverts the traditional folding direction by having panels fold upward toward the ceiling rather than downward or outward. This inversion causes the folding sequence to progress from uppermost to lowermost panel assemblies, with bottom panels moving upward instead of outward, thereby solving the interference and safety problems.

Inventive Principle:
Principle #13The other way round (Inversion)

2Object-affected harmful factors

If a sequential folding mechanism is implemented, then safety and interference reduction are improved, but the device complexity increases

Engineering Contradiction:
Improveinterference and injury riskVSAvoidfolding mechanism complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The wall partition is divided into multiple separate panel assemblies (uppermost, intermediate, and lowermost), each capable of independent sequential folding. This segmentation allows controlled folding progression from top to bottom, enabling safety improvements while managing complexity through modular design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The uppermost panel assemblies are designed to fold first before lower panels move. This preliminary action ensures that folding begins at the top and progresses downward, preventing interference with objects and persons below while maintaining a manageable folding sequence through pre-planned motion hierarchy.

Inventive Principle:
Principle #10Preliminary action

AI summary

A vertically folding wall partition with a set of foldable panel assemblies serially and pivotally connected through a series of vertically spaced apart supports, and a moving mechanism varying a distance between opposed ends of each panel assembly following a downwardly progressing sequence starting with the uppermost panel assembly as the panel assemblies are moved from the deployed position to the folded position, and the moving mechanism varying the distance between the opposed ends of each panel assembly following an upwardly progressing sequence starting with the lowermost of the panel assemblies as the panel assemblies are moved from the folded position to the deployed position.
