Vehicle Shift Lever Integrated Terminal Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing assembly process for vehicle shift levers is complex and time-consuming due to the separate processes required for coupling the knob and rod, as well as transmitting electric signals between them.
Innovation Solution
A shift lever design that integrates a first mounting member with a first connecting terminal and a second mounting member with a second connecting terminal, allowing for simultaneous coupling and signal transmission between the knob and rod, thereby simplifying the assembly and disassembly processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the assembly process for coupling the knob and rod is performed separately from the electric signal transmission connection, then the connection reliability is improved, but the assembly time and process complexity increase
Solution Approach 1:
The patent combines the mechanical coupling function and electric signal transmission function into a single integrated assembly process. The mounting member simultaneously performs both the mechanical connection of the knob to the rod and the electrical connection of the terminals, eliminating the need for separate assembly operations and reducing overall assembly time while maintaining connection reliability
2Manufacturing precision
If multiple separate processes are used for assembling the shift lever components, then the manufacturing precision is improved, but the device complexity and working time increase
Solution Approach 1:
The mounting member is designed as a multi-functional component that simultaneously provides mechanical support, mechanical coupling, and electrical connection functions. This universal component approach reduces the number of separate parts and assembly steps required, simplifying the overall assembly process while maintaining manufacturing precision through integrated design

AI summary
A shift lever for a vehicle includes a knob, a rod coupled to the knob, a first mounting member, and a second mounting member. At least one first connecting terminal is fixed to the first mounting member and at least one second connecting terminal is fixed to the second mounting member. The at least one second connecting terminal comes into contact with the at least one first connecting terminal for transmission of electric signals.
