Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gates, particularly high-speed doors, experience significant noise and mechanical stress due to guide roller systems, leading to wear and tear, which is not effectively addressed by current technologies.
Innovation Solution
The implementation of a guide system where two guide devices form a guide set on a common carrier that can be rotated or displaced, with a sliding piece to stabilize the door leaf and magnetic field generating devices for contact-free guidance, reducing noise and mechanical stress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If guide rollers are used to guide the door leaf movement, then the door can be guided along the specified path, but significant noise is generated and mechanical stress increases
Solution Approach 1:
The patent replaces the traditional mechanical guide roller system with a magnetic field-based guidance system. Magnetic field generating devices create magnetic fields that interact with magnetic elements on the door leaf, providing contact-free guidance along the specified path. This eliminates mechanical contact, thereby reducing noise and mechanical stress while maintaining reliable door guidance.
Solution Approach 2:
The patent introduces magnetic fields as an intermediary between the guide system and the door leaf. Instead of direct mechanical contact between guide rollers and door leaf, magnetic fields serve as the mediating force to guide the door movement, reducing harmful mechanical interactions while maintaining control.
2Reliability
If guide rollers are attached to the door leaf, then the door movement can be guided, but considerable wear occurs on the guide arrangement
Solution Approach 1:
The patent replaces the mechanical guide roller system with a magnetic field-based guidance system. Magnetic field generating devices create magnetic fields that interact with magnetic elements on the door leaf, providing contact-free guidance along the specified path. This eliminates mechanical contact, thereby reducing noise and mechanical stress while maintaining reliable door guidance.
Solution Approach 2:
The patent introduces magnetic fields as an intermediary between the guide system and the door leaf. Instead of direct mechanical contact between guide rollers and door leaf, magnetic fields serve as the mediating force to guide the door movement, reducing harmful mechanical interactions while maintaining control.
3Manufacturing precision
If a common carrier with two guide devices is used, then dimensional accuracy is maintained, but the device complexity increases
Solution Approach 1:
The patent divides the guide system into modular components: a common carrier holding two guide devices, each with magnetic field generating devices. This segmentation allows for pre-assembly and quality control of individual modules while maintaining overall dimensional accuracy. The modular design actually simplifies manufacturing and assembly compared to a fully integrated system.
Solution Approach 2:
The patent combines two guide devices onto a single common carrier, which is then attached to the door leaf as one unit. This merging approach maintains the dimensional accuracy benefits of having two guide devices while simplifying installation and reducing the number of separate components that need to be precisely positioned during assembly.

AI summary
The invention relates to a door comprising a door leaf (10) which can be moved between an open position and a closed position and a guide arrangement for guiding the movement of the door leaf along a predefined path between the open position and the closed position, wherein the guide arrangement has at least one guide web (100) which is arranged fixedly with respect to a wall opening, extends at least along a portion of the predetermined path, and has two outer boundary surfaces (102, 104) and at least two guide devices (32, 34) which are fastened to the door leaf (10), wherein a first outer boundary surface (102) of the guide web (100) forms a guide surface for a first guide device (32) and the second outer boundary surface (104) of the guide web (100) forms a second guide surface (104) for a second guide device (34). Magnetic devices (1000, 1010, 1100) can be arranged on the door leaf and on the guide bar for guiding in a contactless manner.
