Door Guiding Tracks for Barrier Drive Unit Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated barrier movement systems, such as jack shaft operators, face difficulties in assembly and operation due to the need for structural attachments to the wall, which can be challenging when such structures are hidden or not readily accessible, requiring additional construction and carrying a wide array of parts.
Innovation Solution
Attaching the drive unit and jack shaft assembly to the door guiding tracks rather than the wall, allowing for easier assembly and reduced necessary parts, with the option to position the drive unit anywhere relative to the door and using a bayonet mount for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the motor housing is attached to wall studs for structural support, then the reliability of the barrier system is improved, but the ease of installation deteriorates due to difficulty in locating hidden structural parts and requiring additional construction
Solution Approach 1:
The patent introduces door guiding tracks as an intermediary mounting structure between the wall and the motor housing. Instead of directly attaching the motor to wall studs, the tracks serve as a mediator that can be mounted to the wall and then provide attachment points for the motor assembly, eliminating the need to locate and attach to hidden structural parts
Solution Approach 2:
The door guiding tracks are pre-assembled with mounting brackets and attachment points before installation. This preliminary preparation allows the motor housing to be easily attached to the pre-positioned tracks rather than requiring on-site construction or location of hidden wall studs during installation
2Reliability
If the motor is placed above the barrier to function properly, then the operational reliability is improved, but the installation flexibility deteriorates due to restricted positioning options
Solution Approach 1:
The patent makes the motor positioning dynamic and flexible by attaching it to the door guiding tracks rather than fixing it to a specific location above the barrier. The tracks allow the motor to be positioned at various points along the track length while maintaining proper operation, enabling adaptation to different opening sizes and configurations
Solution Approach 2:
The door guiding tracks serve multiple functions: they guide door movement, provide structural support, and serve as a flexible mounting platform for the motor. This multi-functionality allows the motor to be positioned anywhere along the tracks while maintaining both operational reliability and installation flexibility
3Stability of the object's composition
If traditional wall-mounted attachment methods are used, then the structural stability is improved, but the device complexity increases due to requiring additional structural components and assembly steps
Solution Approach 1:
The patent merges the mounting structure function into the door guiding tracks themselves. The tracks are designed with integrated mounting brackets and attachment points that combine the structural support function with the door guidance function, eliminating the need for separate structural components and reducing assembly complexity

AI summary
A support assembly for a barrier movable between open and closed positions over an opening comprises a track. The track is attached to the wall for guiding movement of the barrier between substantially vertical closed position and a substantially horizontal open position. A jack shaft assembly is attached to the track and to the barrier for movement thereof. A mounting assembly is attached to the track for receiving a drive unit comprising a motor for supplying power to the jack shaft assembly to move the barrier and for limiting rotational movement of the drive unit.
