Movable Panel Rotation Guiding Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large movable panel systems face challenges in complexity and functionality due to increased panel dimensions, particularly in vertical movement, affecting the proper functioning of rotation guiding means and weight distribution.
Innovation Solution
The movable panel system incorporates a unique upper guide with a 'U' or 'C' cross-section and an upper carriage assembly with cylindrical or conical central body, allowing for efficient sliding and rotation, along with a bearing carriage assembly for weight distribution, addressing vertical movement and rotation guiding issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If panel dimensions are increased to allow natural lighting, then lighting performance is improved, but system complexity and manufacturing difficulty increase
Solution Approach 1:
The system divides large panels into multiple smaller panel segments that can be individually handled and supported. Each panel is supported at multiple points (upper edge, lower edge, and intermediate points) rather than as a single large unit, reducing the complexity of supporting and handling each individual component while still achieving large spans when assembled.
2Illumination intensity
If panel dimensions are increased longitudinally and vertically, then natural lighting is improved, but handling and supporting complexity increase
Solution Approach 1:
The panel support system is segmented into multiple independent bearing carriages (upper bearing carriage, lower bearing carriage, and intermediate bearing carriages) that can independently support different portions of the panel. This allows each carriage to be designed and operated for smaller, more manageable loads while collectively supporting large panels.
Solution Approach 2:
Intermediate bearing carriages are introduced as intermediary support elements between the upper and lower bearing carriages. These intermediate carriages act as mediators that distribute the panel weight and reduce the span requirements for the primary upper and lower supports, making handling and supporting easier while enabling larger panel dimensions.
3Adaptability or versatility
If vertical movement between upper guide and rotation guiding means occurs, then adaptability is improved, but proper functioning of rotation guiding means deteriorates
Solution Approach 1:
The bearing carriages are designed with dynamic adjustment capabilities that allow them to adapt to vertical movements and maintain proper engagement with the panel edges. The bearing carriages can adjust their vertical positions dynamically while maintaining reliable rotation guiding function, resolving the conflict between adaptability and reliability.

AI summary
A movable panel system (1) comprising: - a lower guide (2) extending along a longitudinal axis (X-X), an upper guide (3) comprising an upper channel (30) and at least one panel (4a, 4b, 4c,) preferably made of glass; - rotation and sliding means allowing for the sliding and rotation of the panel (4a, 4b, 4c); - rotation guiding means at least partially housed within the upper channel (30), comprising a main guiding device (62) comprising a main guiding wall (620), and an auxiliary guiding device (61) comprising an auxiliary guiding wall (613'), supported by an upper carriage assembly (51). The panel is configurable in a sliding configuration, wherein it is longitudinally slidable, and an end configuration, wherein it is rotatable and the auxiliary guiding wall (613') is slidingly engagable to the main guiding wall (620), in such a way as to be reciprocally movable vertically.
