Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gearshift lever assemblies in motor vehicles face challenges such as noise associated with lever movements, reduced pleasantness of the shifting experience, and increased dimensions of mechanical members, which affect the overall fluidity and engagement of gear shifts.
Innovation Solution
A gearshift lever assembly utilizing a support base, a lever body, and a system of magnets where a first magnet is fixed to the lever body and corresponding second magnets are positioned at each predetermined lever position on the support base, creating magnetic attraction to stabilize and guide the lever through its positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If friction or mechanical cooperation between transmission members is used to ensure lever stability and position feelings, then the lever can be stabilized at predetermined positions, but noise is generated and the mechanical members increase in dimension
Solution Approach 1:
The patent replaces the traditional mechanical friction-based positioning system with a magnetic field-based system. Magnets are embedded in the lever body and corresponding magnets are positioned in the support base at predetermined positions. The magnetic attraction forces provide the stabilizing effect without mechanical contact, thereby eliminating noise generated by friction and mechanical cooperation while maintaining lever stability at all predetermined positions.
2Stability of the object's composition
If friction or mechanical cooperation between transmission members is used to ensure lever stability and position feelings, then the lever can be stabilized at predetermined positions, but the mechanical members increase in dimension
Solution Approach 1:
The patent replaces bulky mechanical transmission members with compact magnets. The magnetic field extends through space without requiring physical contact, allowing the lever positioning system to be significantly more compact than traditional mechanical systems. The magnets embedded in the lever body and support base create the necessary stabilizing forces without requiring large-dimensional mechanical components.
3Stability of the object's composition
If mechanical cooperation between transmission members is used to provide lever position feelings, then the lever can be stabilized at predetermined positions, but the overall fluidity of lever movements is reduced
Solution Approach 1:
The magnetic field-based system provides smooth, contactless interaction between the lever and support base. As the lever moves through predetermined positions, the magnetic attraction forces create a fluid sensing experience without the resistance and abrupt engagement characteristic of mechanical friction systems. This enhances the overall fluidity of lever movements while maintaining stable positioning at each gear position.

Function Achieved in This Case
The magnetic system provides a stable and smooth shifting experience with reduced noise and wear, enhances the feeling of fluidity and engagement during gear changes, and allows for a more compact design of the mechanical members.
Implementation Method 1
the second pole magnetically cooperates with the first pole when the lever body is in the corresponding predetermined position of said predetermined positions, so that the corresponding second magnet exerts a magnetic attraction on the first magnet

AI summary
A gearshift lever assembly includes a support base, a lever body coupled to the support base in a movable manner along a path comprising a plurality of predetermined positions relative to the support base, a first magnet fixed with respect to the lever body and having a first magnetic pole, and at least one corresponding second magnet for each one of said predetermined positions, the second magnet having a relative second magnetic pole opposite the first magnetic pole and being carried by the support base in a relative fixed position, such that said second pole magnetically co-operates with the first pole when the lever body is in the corresponding predetermined position between said predetermined positions, so that the corresponding second magnet exerts a magnetic attraction upon the first magnet.
