Pivoting Division Bar Window System for Full Door Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional automotive hardware systems often fail to accommodate the full lowering of a window and division bar below the beltline due to the shape and size constraints of rear side doors or front doors with outside rearview mirrors, leading to compromises that limit window opening size, ventilation, and increase system complexity and cost.
Innovation Solution
A motor and cable drive system with a guide rail system, pivotally mounted division bar, and biasing element allows the window and division bar to be fully lowered into the door panel, utilizing a regulator to displace them between a closed and opened position, with the division bar pivoting to clear the door structure and be concealed within the panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the window or door glass does not drop completely below the belt line, then the window structure can be accommodated within the door panel, but the vehicle occupant does not have a comfortable place to rest his arm and ventilation is limited
Solution Approach 1:
The division bar is made dynamically movable through pivotal movement about a pivot pin, transitioning from a fixed position to a lowered position where it clears the door structure. This dynamic capability allows the window to be fully lowered below the belt line, providing both complete opening volume and arm resting space while maintaining structural accommodation within the door panel.
2Ease of operation
If the size of the movable portion of the window is reduced, then the window can be fully opened and dropped into the door panel, but the size of the window opening above the door is limited
Solution Approach 1:
The window assembly is segmented into the window glass and the division bar as separate but connected components. The division bar can be independently pivoted to a lowered position, allowing the window glass to be fully lowered without being constrained by the division bar's position. This segmentation enables the full window opening area to be achieved while maintaining complete opening capability.
3Ease of manufacture
If traditional automotive hardware systems are used, then the system structure is simple, but the shape of the lower door structure does not accommodate the complete lowering of a full door glass window
Solution Approach 1:
A regulator mechanism is introduced to dynamically control the positioning of the window and division bar. The regulator enables the window to be fully lowered below the belt line by providing controlled movement, while the division bar pivots independently to clear the door structure. This dynamic system maintains manufacturing simplicity by using straightforward mechanical components while achieving complete window lowering volume.
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
Enables a full-size window opening above the door panel while maintaining a simple, cost-effective, and easy-to-manufacture system that provides enhanced ventilation and convenience by fully concealing the window and division bar within the door panel.
Implementation Method 1
the biasing element may be a torsion spring concentrically received over the pivot pin
Implementation Method 2
The regulator may comprise a motor and cable drive system concealed within the internal compartment

AI summary
An apparatus includes a door panel having a window receiver and an internal compartment, a window and a division bar pivotally mounted on the pivot. The apparatus also includes a regulator carried on the door panel. The regulator displaces the window and the division bar between a closed position projecting from the window receiver and an opened position concealed fully within the internal compartment of the door panel.
