Vehicle Window Pivot and Translation Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle window designs lack the ability to efficiently transition between a closed and open position while maintaining a flush outer surface alignment with the vehicle body, which can lead to gaps and reduced sealing effectiveness.
Innovation Solution
A window assembly with a track and pivot system that allows the window to translate and pivot, using a lift actuator and pivot actuator to move between closed and open positions, ensuring the outer surface remains flush with the vehicle body when closed and can be fully or partially inside the vehicle when open.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a conventional window design is used, then the structure is simple, but the window cannot maintain flush alignment with the vehicle body during movement between closed and open positions
Solution Approach 1:
The window mechanism transitions from a static conventional design to a dynamic system that actively adjusts the window's position and orientation. The pivot assembly enables the window to rotate and pivot during movement, maintaining flush alignment with the vehicle body exterior throughout the transition from closed to open positions, rather than relying on a fixed movement path.
Solution Approach 2:
The invention adds rotational and pivoting dimensions to the window's movement beyond simple linear translation. The pivot assembly introduces angular movement capabilities, allowing the window to rotate about vertical and horizontal axes, transforming the movement from one-dimensional (vertical only) to multi-dimensional (vertical + rotational + pivoting).
2Reliability
If a conventional window design is used, then the mechanism is simple, but sealing effectiveness is reduced due to gaps during transition
Solution Approach 1:
The dynamic adjustment capability allows the window to maintain optimal sealing contact with the vehicle body throughout the entire movement cycle. By actively pivoting and rotating during transition, the window keeps its outer surface flush against the body, preventing gaps that would compromise sealing effectiveness, unlike static conventional designs.
Solution Approach 2:
The pivot assembly performs preliminary positioning adjustments before the window completes its movement to the open or closed position. This preliminary action ensures the window is already aligned and flush with the vehicle body, preparing the sealing surfaces for optimal contact and preventing gaps before the transition is complete.
3Ease of operation
If the window is fully lowered into the interior space, then the open position is achieved, but the outer surface is no longer flush with the vehicle body
Solution Approach 1:
The invention adds rotational and pivoting dimensions to the window's movement beyond simple linear translation. The pivot assembly introduces angular movement capabilities, allowing the window to rotate about vertical and horizontal axes, transforming the movement from one-dimensional (vertical only) to multi-dimensional (vertical + rotational + pivoting).
