Vehicle Vent Toggle Structure for Thick Front Blade Styling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing length and thickness of air outlet front blades in vehicle air conditioning vents make it difficult to wrap the toggle structure around, leading to a poor visual appearance and weakened toggle movement due to the need for thicker blades and larger toggle contours.
Innovation Solution
A toggle assembly is designed with a toggle bracket and toggle blade that is mounted in a cavity between the air outlet front blade's vane portions, featuring a snap-in fit mechanism and a fork structure to drive the rear blade, allowing for adjustable airflow directions without wrapping around the front blade, thus maintaining aesthetics and structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the air outlet front blade is made longer and thicker to meet modern styling requirements, then the visual appearance is improved, but the toggle structure becomes difficult to wrap around and its movement is weakened
Solution Approach 1:
The toggle structure is extracted from the traditional wrapped-around configuration and repositioned to be mounted on the inner side of the front blade. This separation allows the front blade to maintain its longer, thicker modern styling while the toggle structure operates independently without being constrained by the blade's external dimensions, thus resolving the contradiction between visual appearance and toggle movement ease.
Solution Approach 2:
The toggle structure is relocated from the external wrapping position to the internal mounting position on the inner side of the front blade. This dimensional repositioning allows the toggle to operate within the blade's internal space, eliminating the interference between the toggle's wrapping path and the blade's increased length and thickness, thereby maintaining both aesthetic appearance and operational ease.
2Strength
If the front blade is thickened to maintain structural integrity, then strength is improved, but the toggle structure becomes more complex and visually bulky
Solution Approach 1:
The toggle structure is extracted from the external wrapping configuration and relocated to the inner side mounting position. This extraction simplifies the toggle structure by eliminating the need for complex wrapping mechanisms around thick blades, while the front blade can be thickened for strength without increasing toggle complexity.
Solution Approach 2:
Instead of mounting the toggle on the outer side of the front blade as in traditional designs, the toggle is inverted to be mounted on the inner side. This inversion allows the toggle to operate within the blade's internal space, reducing structural complexity while enabling the blade to be thickened for strength without affecting toggle design complexity.
3Reliability
If the toggle contour is enlarged to accommodate thicker blades, then blade support is improved, but the overall structure becomes larger and more cumbersome
Solution Approach 1:
The toggle structure is extracted from the external support configuration and repositioned to the inner side mounting position. This allows the toggle to provide blade support through internal mounting mechanisms rather than external envelopment, reducing the toggle's external volume while maintaining reliable blade support functionality.
Solution Approach 2:
The toggle mounting is relocated from the external dimension to the internal dimension of the front blade. This dimensional change allows the toggle to support the blade effectively through internal attachment points without requiring an enlarged external contour, thus reducing the moving object volume while maintaining support reliability.
