Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional window lift mechanisms in motor vehicles often suffer from misalignment between the window's translation axis and the slider's axis, leading to jamming, noise, and increased effort during operation, especially in 'flush' window configurations where perfect parallelism is difficult to achieve.
Innovation Solution
Incorporating a pane support device with elastically deformable material elements that provide three degrees of linear movement freedom between the slider and the window, allowing for compensation of mounting inaccuracies and ensuring reliable operation without requiring perfect parallelism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional window lift mechanism is used with fixed alignment, then the structure is simple, but misalignment between the window's translation axis and the slider's axis causes jamming, noise, and increased effort during operation
Solution Approach 1:
The support device incorporates elastic elements that allow dynamic adjustment of the window's position relative to the slider. The elastic elements enable the support to adapt its configuration automatically during window movement, compensating for misalignment between the translation axis and slider axis, thereby eliminating jamming and noise while maintaining operational reliability.
Solution Approach 2:
The elastic elements in the support device allow for parameter changes in the relative position and orientation of the window compared to the slider. By permitting small deviations in position and angle through the elastic deformation, the system compensates for manufacturing tolerances and assembly variations, ensuring smooth operation without requiring perfect initial alignment.
2Ease of operation
If perfect parallelism between the window's translation axis and the slider's axis is required, then operation is smooth, but assembly becomes difficult and time-consuming
Solution Approach 1:
The support device with elastic elements performs self-adjustment during assembly and operation. The elastic components automatically compensate for misalignment between the window axis and slider axis, eliminating the need for precise manual alignment during assembly. The system self-corrects positional deviations, making assembly easier while ensuring smooth operation.
Solution Approach 2:
The dynamic nature of the elastic support allows it to adapt to slight misalignments automatically. During assembly, the elastic elements can deform to accommodate variations in positioning, and during operation, they continuously adjust to maintain optimal alignment, ensuring smooth window movement without requiring perfect initial parallelism.
3Reliability
If rigid connection between slider and window is used, then structural simplicity is maintained, but misalignment causes jamming and noise
Solution Approach 1:
The support device uses elastic elements that function as flexible components between the rigid slider and window. These flexible elements allow for small deformations to accommodate misalignment, preventing jamming and noise while maintaining the overall structural simplicity. The flexibility is localized only where needed for compensation, not throughout the entire structure.
Solution Approach 2:
The elastic elements in the support device provide beforehand cushioning against misalignment issues. By incorporating these compliant elements in advance, the system is prepared to absorb and compensate for positional deviations before they cause jamming or noise, ensuring reliable operation without requiring complex adjustment mechanisms.
