Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door drives with rail guides are prone to maintenance issues and are not ideal for space efficiency, and they often require specific designs for different door shapes, limiting versatility.
Innovation Solution
A door drive system featuring a carrier with a swivel arm and pivoting lever that converts rotational movement into linear motion, allowing for various door shapes to be used with minimal space requirements, without the need for a rail guide, and includes additional support mechanisms for enhanced functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a sliding mechanism with rail guide is used, then space efficiency is improved, but maintenance reliability deteriorates
Solution Approach 1:
The patent removes the rail guide component from the system entirely. Instead of using a sliding mechanism that requires rails, the invention employs a pivot arm mechanism that achieves space efficiency without the maintenance-prone rail guide infrastructure.
Solution Approach 2:
The patent replaces the sliding mechanism with a pivot-based mechanical system. The pivot arm rotates about a pivot axis to achieve door movement, substituting the rail-guided sliding motion with a simpler pivot mechanism that eliminates the need for complex rail guides.
2Ease of operation
If a rail guide system is used, then door movement control is improved, but device complexity increases
Solution Approach 1:
The patent eliminates the rail guide system that provides door movement control, replacing it with a pivot arm mechanism that achieves similar control functionality with simpler components and fewer parts.
Solution Approach 2:
The patent divides the door drive into distinct functional segments: the pivot arm for movement, the actuating means for driving, and the support structure for mounting. This segmentation allows each component to perform its function independently, reducing overall system complexity.
3Ease of manufacture
If a fixed door drive design is used, then manufacturing simplicity is improved, but adaptability deteriorates
Solution Approach 1:
The patent designs a universal door drive mechanism that can accommodate various door shapes and configurations. The pivot arm and actuating means are configured to work with different door types, eliminating the need for separate drive designs for each door shape.
Solution Approach 2:
The patent employs a dynamic pivot arm mechanism that can adapt its movement trajectory and range to accommodate different door shapes. The actuating means can be adjusted or configured to provide appropriate actuation for various door configurations, enhancing versatility.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides a space-efficient and maintainable door drive that can accommodate different door shapes, ensuring reliable operation and easy replacement of door leaves, with automatic positioning and locking mechanisms for enhanced functionality.
Implementation Method 1
The pivot lever is further connected to drive means that can rotate the pivot lever in a semicircle around a drive axis. The free end of the pivot lever engages in a linear guide of the swivel arm... so that a rotation of the pivot lever is translated into a forward and backward movement of the swivel arm.
Implementation Method 2
The pivot lever has an engagement element at its end, depending on the design of the linear guide, for example, in the form of a sliding roller or a ball-bearing slide, so that this engagement element slides within the linear guide.

AI summary
2.1 What is sought is the pushing in of access restriction doors laterally in the manner of a sliding door so that as space-saving as possible of a solution can be implemented. However, what is not desired in this regard is the providing of linear drives and using track systems since they require maintenance and in particular must be kept clean. Thus, the object of the invention is to provide a door drive which also requires very little space but nevertheless does not require the use of a track guide. 2.2 This is accomplished by a tilt arm that can move the door back and forth between a blocking position and a release position through suitable actuating means such as of a tilt arm. In an improvement, a nearly completely linear movement of the door leaf can be made using an additional support arm. 2.3 Drive for doors for access restriction.
