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 sliding, support, and gripping means, including trolley devices with vertical and horizontal wheels, and a gripping group with wedge elements, to facilitate efficient axial translation and rotational movement of panels, ensuring they remain stable and upright even when cantilevered.

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 due to their weight and dimensions

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

Solution Approach 1:

The panel handling system is segmented into multiple functional components: upper guide, lower guide, trolley devices with vertical and horizontal wheels, and gripping means. This segmentation allows each component to address specific aspects of panel handling, distributing the load and control functions across multiple elements rather than requiring a single complex mechanism.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system employs multiple pairs of vertical wheels and horizontal wheels that engage with the panel at different points. This excessive action ensures that even though the panels are large and heavy, multiple contact points provide sufficient support and control to prevent tilting while maintaining ease of operation.

Inventive Principle:
Principle #16Partial or excessive action

2Ease of operation

If special guides and sliding means are provided to enable axial translation and rotational movement, then the ease of operation is improved, but the device complexity increases

Engineering Contradiction:
ImprovemovementVSAvoidcomplexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The upper guide and lower guide are merged into a coordinated system where both guides work together to provide axial translation and rotational movement. The trolley devices combine multiple wheel pairs (vertical and horizontal) into single integrated units that attach to the panels, reducing the overall number of separate components while maintaining full functionality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The guide system is designed with multi-functionality: the same upper and lower guides facilitate both axial translation along the guide axis and rotational movement around the vertical axis. The trolley devices serve multiple purposes by providing both support during translation and enabling rotation, reducing the need for separate mechanisms for each motion type.

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

3Ease of operation

If the panel is supported only on one side with the other rotated outside the guide, then the ease of operation is improved, but the panel tilts and assumes an undesirable appearance

Engineering Contradiction:
ImproverotationVSAvoidstability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The system uses horizontal wheels that engage with the upper guide to provide counterbalancing support during rotation. These horizontal wheels act as a counterweight mechanism, distributing the panel's weight forces and preventing the panel from tilting outward when rotated, thus maintaining stability while enabling easy rotation.

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

Solution Approach 2:

The gripping means and wheel arrangement are designed to distribute the panel's weight forces evenly during rotation. By positioning the vertical and horizontal wheels to engage at specific points on the panel, the system creates an equipotential support distribution that prevents tilting and maintains the panel in a stable, upright position throughout the rotation motion.

Inventive Principle:
Principle #12Equipotentiality
