Moveable Steering Column Nested Jacket Telescoping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional steering column assemblies require excessive space due to their design, which is a limitation in applications where space is constrained, such as in autonomous vehicles where the steering column needs to be stowed out of the way to accommodate other devices.
Innovation Solution
A moveable steering column assembly with a first jacket that translates axially and a second jacket that telescopes within the first, actuated by a single or multiple electromechanical actuators, allowing for simultaneous or sequential telescoping and translating motion to optimize space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional telescoping solutions are used, then the steering column can be adjusted, but the space required by the steering column assembly increases
Solution Approach 1:
The patent implements a nested jacket configuration where the second jacket is telescopically engaged within the first jacket. This nesting arrangement allows the steering column to telescope in a compact manner, with one jacket portion sliding inside another, thereby reducing the overall space required while maintaining adjustability functionality.
Solution Approach 2:
The patent employs dynamic telescoping mechanisms that allow the steering column to change its configuration between extended and retracted states. The actuators enable the jackets to move relative to each other, providing dynamic adjustment capability that maintains operational flexibility while minimizing space when retracted.
2Volume of moving object
If the steering column is made compact for stowing, then space is saved, but the complexity of the telescoping mechanism increases
Solution Approach 1:
The patent combines multiple telescoping functions into a unified mechanism where a single actuator can control the relative movement between jackets. This merging of functions reduces the number of separate components needed, thereby reducing overall system complexity while achieving compact telescoping capability.
Solution Approach 2:
The actuators are designed to perform multiple functions: they control both the telescoping movement of the second jacket within the first jacket and the axial translation of the first jacket. This multi-functionality reduces the number of separate actuators needed, simplifying the overall mechanism while maintaining compact adjustment capability.
