Bow-Shaped Control Curve for Door Guide Rail Transitions
Solution Overview
Problem
Existing guide systems for movably supported door wings face issues such as collision with U-shaped limbs during right-angled transitions and require high manual effort for parallel movement, and existing solutions for movable wall elements have increased constructional effort and space requirements.
Innovation Solution
A bow-shaped control curve is introduced in the transition region between the first guide rail and the carrier, allowing the guide carriage to maintain kinetic energy and smoothly transition to the second guide rail, with a locking device to facilitate intuitive movement and reduce manual effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a right-angled transition is used between the first guide rail and the second guide rail, then the guide system can achieve compact layout, but the guide element collides with the U-shaped limbs of the guide rails impeding insertion movement
Solution Approach 1:
The patent replaces the right-angled transition with a bow-shaped control curve that has a curved geometry. This curved transition guide allows the guide element to smoothly follow the curve without colliding with the U-shaped limbs, eliminating the collision problem while maintaining compact layout through the curved path design.
2Ease of operation
If a bow-shaped control curve is introduced for smooth transition, then collision is prevented and movement is facilitated, but the device complexity increases
Solution Approach 1:
The bow-shaped control curve is integrated as part of the transfer device structure, merging the transition guidance function into the existing carrier and guide rail assembly. This integration approach adds the curved transition functionality without requiring completely separate components, thereby limiting the increase in device complexity.
3Device complexity
If door wings are moved in parallel position requiring high manual effort, then the guide system can maintain simple structure, but the ease of operation deteriorates
Solution Approach 1:
The bow-shaped control curve acts as an intermediary element between the first guide rail and the second guide rail. It mediates the transition by providing a curved path that reduces the manual effort required for parallel movement, while the overall guide system structure remains relatively simple through this intermediary mechanism.

AI summary
A guide system includes a first guide rail, a guide carriage configured to be connected to the door wing and configured to run along the first guide rail, a second guide rail separate from the first guide rail, the second guide rail extending transversely to the first guide rail in a mounted condition, a carrier configured to be displaceable relative to the second guide rail, the guide carriage can be arranged on the carrier, and a transfer device for transferring the guide carriage at least from the first guide rail to the carrier. The transfer device includes a control curve configured to be bow-shaped at least over a region, so that the guide carriage, upon a transfer from the first guide rail to the carrier, can be moved at least over a region in a direction of the second guide rail.
