Solution Overview

Problem

Large glass panels in pack-wise movable panel systems tend to tilt when rotated, giving an undesirable appearance and suggesting weakness and unreliability due to their size and weight, which existing hinge devices fail to adequately support.

Innovation Solution

A hinging device with a carrying body and gripping means, featuring a rotation shaft, engagement elements, and low-friction guide elements, which securely supports and locks the panels in a vertical position during rotation, preventing tilting by threading engagement elements and utilizing wheels or rollers for sliding and rotation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If large glass panels are used to allow effective illumination, then illumination intensity is improved, but the panels tend to tilt when rotated due to their size and weight

Engineering Contradiction:
ImproveilluminationVSAvoidpanel stability
Core Design Contradiction:
Illumination intensityVSStability of the object's composition

Solution Approach 1:

The hinging device is divided into separate functional components: a carrying body for supporting the panel, a rotation shaft for enabling rotation, and gripping means with engagement elements for securing the panel. This segmentation allows each component to be optimized for its specific function, with the gripping means specifically designed to prevent tilting while supporting large panels.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The engagement elements interact through mutual threading in a rotational motion pattern, creating a two-dimensional engagement path that provides stable support during the transition from closed to open position. This dimensional approach to the engagement mechanism prevents the panel from tilting outward.

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

2Ease of operation

If panels are rotated to open position for ventilation, then ease of operation is improved, but the panels assume an undesirable tilted appearance suggesting weakness

Engineering Contradiction:
Improvepanel rotationVSAvoidsystem reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The gripping means with mutually threading engagement elements apply a counteracting force during panel rotation to prevent the outward tilting motion before it can occur. This preliminary anti-action ensures the panel maintains vertical alignment throughout the rotation, preventing the undesirable tilted appearance that suggests system weakness.

Inventive Principle:
Principle #9Preliminary anti-action

3Device complexity

If existing guides are not modified, then device complexity is reduced, but the hinging device must independently handle all support and rotation functions

Engineering Contradiction:
Improveguide modificationVSAvoidsliding functionality
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The carrying body serves multiple functions: it supports the panel vertically, enables rotation through the rotation shaft, and provides gripping through the engagement elements. This multi-functionality allows the hinging device to handle all support and rotation operations without requiring modifications to the existing guide structure, maintaining sliding functionality while reducing overall system complexity.

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