Two-seater kart steering wheel locking pin mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current two-seater karts require costly investments and complex mechanical interventions to switch between baptism and driving lesson modes, lacking a simple and inexpensive solution to quickly modify their functionality between kart baptism and driving lessons, and do not allow for easy transition between instructor-controlled and learner-controlled operations.
Innovation Solution
A two-seater kart with a steering assembly that includes a locking pin mechanism, allowing one steering wheel to be quickly deactivated, enabling easy transformation between active and inactive states without disassembly, and allowing both users to control the kart or restrict passenger input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two distinct types of two-seater karts are maintained (one with one active steering wheel for baptisms, another with two active steering wheels for driving lessons), then the functionality for both baptism and driving lessons is provided, but costly investments and device complexity increase
Solution Approach 1:
The steering wheel's functionality is made dynamic through a movable locking pin that can switch between two positions: engaging with the steering column to enable active steering control, or engaging with the frame to deactivate the steering wheel. This dynamic mechanism allows a single kart to adapt between baptism mode (one active wheel) and driving lesson mode (two active wheels) without requiring separate vehicles, thereby reducing device complexity while maintaining versatility
Solution Approach 2:
Each steering wheel is designed with universal functionality to serve multiple purposes: it can be actively connected to the steering column for control, or passively connected to the frame as a static support element. This multi-functionality eliminates the need for separate specialized karts, allowing one kart to fulfill both baptism and driving lesson requirements
2Ease of operation
If mechanical intervention is performed to disassemble elements and render an active steering wheel inactive, then the steering wheel can be deactivated, but the process requires experienced mechanic intervention and becomes difficult to modify
Solution Approach 1:
The locking pin mechanism enables operators to independently activate or deactivate steering wheels without requiring mechanic intervention. The operator simply moves the locking pin between positions, allowing the kart to be quickly reconfigured between baptism and driving lesson modes. This self-service capability significantly improves ease of operation and reduces modification difficulty
3Productivity
If a locking pin mechanism is implemented to deactivate steering wheels, then quick and easy modification is enabled without mechanical tools, but the device complexity increases
Solution Approach 1:
The steering assembly is segmented into independent controllable units, with each steering wheel equipped with its own locking pin mechanism. This segmentation allows individual steering wheels to be activated or deactivated independently and quickly, enabling fast mode switching. The added complexity is localized to simple locking mechanisms rather than requiring complex overall system redesign

AI summary
The invention relates to a two-seater cart comprising a chassis (10) on which there are mounted two seats and a steering assembly (15, 16) bearing at least two steering wheels (131, 132). According to the invention, a two-seater cart such as this comprises means of deactivating one of the steering wheels, comprising a locking stud. Thus, such a steering wheel can adopt: - an inactive state in which it is secured to the chassis; - an active state in which the steering wheel is able to drive a steering column. The steering wheel passes from the active state to the inactive state, and vice versa, by the moving of the locking stud.
