Spline-Telescopic Steering Column With Integrated Ignition Controls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf cart steering columns are not telescopic, lacking flexibility and comfort due to fixed lengths, and do not integrate light control and ignition modules, impacting user convenience and safety.
Innovation Solution
A telescopic multifunctional steering column design featuring an upper and lower column connected via a spline shaft and groove, with a pull bolt mechanism for adjustable length, and integrated housing assemblies for light control and ignition modules, enhancing flexibility, safety, and user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-length steering column is used, then the structure is simple, but the adaptability and driving comfort are poor
Solution Approach 1:
The steering column is divided into an upper column and a lower column that can slide relative to each other. The upper column is inserted into the lower column, creating a telescopic structure that allows length adjustment while maintaining structural simplicity
Solution Approach 2:
The steering column transitions from a fixed static structure to a dynamic telescopic structure. The upper and lower columns can slide relative to each other to adjust the steering column length according to different driving conditions and driver needs
2Adaptability or versatility
If a telescopic steering column is added, then the adaptability and comfort are improved, but the device complexity increases
Solution Approach 1:
The steering column is segmented into movable upper column and stationary lower column portions, allowing independent movement and adjustment while keeping each component relatively simple in design
Solution Approach 2:
The upper column is nested within the lower column, with the outer surface of the upper column sleeved by the lower column. This nesting arrangement allows telescopic movement while maintaining a compact overall structure
3Ease of operation
If only a single-function steering column is used, then the device complexity is low, but the ease of operation and user-friendliness are poor
Solution Approach 1:
Multiple functions (light control, ignition control, and steering) are merged into a single integrated steering column assembly. The housing assembly incorporates both the light control module and ignition module, allowing all controls to be accessed from one location
Solution Approach 2:
The steering column is designed as a multi-functional universal control center, integrating steering control, lighting control, and ignition control into one device, eliminating the need for separate control mechanisms
4Ease of operation
If light control module and ignition module are integrated, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The light control module and ignition module are merged into a single housing assembly that is integrated with the steering column, consolidating multiple control functions into one unified structure
Solution Approach 2:
The housing assembly serves multiple functions simultaneously - it houses the light control module, the ignition module, and provides structural support for the telescopic mechanism, demonstrating multi-functionality that reduces overall system complexity

AI summary
The disclosure relates to the technical field of steering columns, and specifically discloses a telescopic multifunctional steering column. An upper column is fixedly mounted inside a steering wheel. An outer surface of the upper column is sleeved with a lower column. In the disclosure, slidable connection is realized through a spline groove and a spline shaft, so that the steering column can extend and retract, which ensures stability and sliding smoothness of the column during the extension and retraction process. By connecting a pull bolt with a locking switch of a lifting rod through a wire rope, when the pull bolt is pulled up, a driver can adjust a length of the column according to his own needs, which improves driving flexibility and comfort. When the pull bolt retracts, the steering column is locked at a selected position.
