Swing-up Wall Pivot Mechanism for Low Lintel Height
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing swing-up wall solutions require high lintel heights, making them unsuitable for low buildings and transparent structures like swimming pool roofs, and fail to meet design and aesthetic requirements for architecturally demanding areas.
Innovation Solution
A device using an electric motor drive or energy accumulator with a cable pull system that allows the swing-up wall to pivot with minimal lintel height, utilizing a cable pull on both sides and a pivot pin for efficient power transmission and low-profile design, enabling the swing-up wall to be pulled close to the ceiling without obstructing the view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cable pull connected to a counterweight acts on the swing-up wall to pivot it from vertical closed position to horizontal open position, then the swing-up wall can be moved between positions, but it swings outwards and protrudes beyond the contour of the adjacent building during the swiveling process
Solution Approach 1:
The patent changes the movement path from a simple outward swing to a three-dimensional trajectory that moves the wall both horizontally and vertically. The wall is guided along a curved path defined by the arch-shaped rail guide, allowing it to clear the building contour by moving into the vertical dimension rather than simply swinging outward horizontally.
Solution Approach 2:
The patent introduces an arch-shaped rail guide as an intermediary element between the swing-up wall and the building structure. This rail guide mediates the movement by providing a constrained path that prevents the wall from protruding beyond the building contour while still allowing full pivoting motion from closed to open position.
2Ease of operation
If roller doors with slats are used with cable pulls on both sides of the lower end, then the pivoting wall can be moved from vertical closed position to horizontal closed position, but a lintel covering the arch must be designed, increasing the lintel height requirement
Solution Approach 1:
The patent extracts the lintel element from the structure by eliminating the need for a high lintel covering the arch. The swing-up wall design allows the wall itself to form the closing element without requiring a separate lintel structure, thereby removing the constraint on lintel height.
Solution Approach 2:
Instead of having the lintel cover the arch and determine the opening height, the patent inverts the approach by having the swing-up wall move along the arch-shaped rail guide. The wall becomes the active element that defines the opening, rather than the lintel being a passive structural element that constrains the opening.
3Adaptability or versatility
If a round arch connects the vertical and horizontal rail guides, then the transition between positions is enabled, but the arrangement requires a certain lintel height and spaces the roller door from the ceiling by approximately the height of the lintel
Solution Approach 1:
The patent makes the swing-up wall multi-functional by having it serve both as the closing element and as the moving component that transitions between positions. The wall performs multiple functions: it closes the opening when vertical, pivots to open the opening when horizontal, and simultaneously follows the arch-shaped rail guide, eliminating the need for separate lintel and rail structures.
4Extent of automation
If electric motor drives with link devices are used to wind up the roller shutter, then automatic operation is achieved, but the solution requires very high lintel heights which limit window height in low buildings and is perceived as unattractive
Solution Approach 1:
The patent replaces the traditional mechanical link device and roller shutter system with a cable pull mechanism acting directly on the swing-up wall. This substitution eliminates the need for complex winding mechanisms and high lintels, allowing for cleaner architectural lines and greater design flexibility in low buildings.

AI summary
The device has a drive device e.g. electric motor drive such as linear motor, or an energy accumulator attached to a highly tiltable wall (1) such that the wall is drawn by the drive device or the energy accumulator into a horizontal guide rail (5) arranged in an upper area of a building e.g. garage, or a building part e.g. gable or swimming pool roofing. A Bowden cable (3) is attached on both sides of the wall, where ends of the cable are connected with the wall and the accumulator or the drive device, respectively.
