Solution Overview

Problem

Large glass panels in packable movable panel systems are difficult to handle due to their size and weight, often tilting undesirably when in the open position, which affects their appearance and functionality.

Innovation Solution

The system employs a combination of upper and lower guides with specialized trolley devices and gripping means, including horizontal and vertical wheels, and a pin element to facilitate efficient axial translation and rotational movement, ensuring the panels remain stable and aligned during rotation and packing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If large glass panels are used to provide effective illumination, then the illumination intensity is improved, but the panels become difficult to handle and tend to tilt

Engineering Contradiction:
ImproveilluminationVSAvoidhandling
Core Design Contradiction:
Illumination intensityVSEase of operation

Solution Approach 1:

The patent introduces trolleys as intermediary devices between the glass panels and the guides. These trolleys include support wheels that contact the panels and guide wheels that engage with the guides, mediating the force transmission and reducing direct handling difficulty. The trolleys act as mechanical intermediaries that make it easier to move and position large, heavy glass panels along the curved path.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If panels are supported only on one side in a cantilevered position, then the rotational movement is simplified, but the panels tend to tilt and assume an undesirable appearance

Engineering Contradiction:
Improverotational movement mechanismVSAvoidpanel stability
Core Design Contradiction:
Device complexityVSStability of the object's composition

Solution Approach 1:

The patent employs a pair of trolleys positioned at opposite ends of each glass panel to provide balanced support. When one trolley is rotated outside the guide, the other trolley remains inside, creating a counterbalancing effect that prevents the panel from tilting. This anti-weight arrangement maintains panel stability during the cantilevered rotational movement, preventing the undesirable tilting appearance while preserving the simplified rotational mechanism.

Inventive Principle:
Principle #8Anti-weight (Counterweight)

3Adaptability or versatility

If special guides and sliding means are provided for axial translation and rotation, then the movement capability is improved, but the device complexity increases

Engineering Contradiction:
Improvemovement capabilityVSAvoidguides and sliding means
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent designs the guides with a universal structure that serves multiple functions: they provide axial translation guidance through guide wheels, enable rotational movement through the curved path, and support the panels during packing and unpacking operations. The same guide structure accommodates both linear and rotational movements, as well as the cantilevered positioning, reducing the need for separate specialized mechanisms for each function.

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