Steering Wheel Display Mount That Stays Fixed During Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing steering devices with displays mounted on steering wheels rotate with the wheel, making it inconvenient for drivers to view information, and existing solutions cannot be applied to steer-by-wire systems without a steering column and support.
Innovation Solution
A steering device with a display that uses an adapter to fix the display in a non-rotating position, connected to a steering feedback device with a fixed and rotating portion, allowing the display to remain stationary even when the steering wheel rotates, utilizing a torsion bar and shafts to maintain the display's fixed state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display is mounted directly on the steering wheel, then the display rotates with the steering wheel, but this makes it inconvenient for the driver to view displayed information
Solution Approach 1:
The steering wheel assembly is segmented into a rotating steering wheel portion and a fixed display support portion. The display is mounted on the fixed support portion rather than directly on the steering wheel, allowing the steering wheel to rotate independently while the display remains stationary for easy driver viewing.
Solution Approach 2:
Instead of mounting the display on the rotating steering wheel (conventional approach), the patent inverts the mounting approach by fixing the display to a non-rotating support structure while allowing the steering wheel to rotate freely, thus solving the viewing convenience problem.
2Stability of the object's composition
If a steering column and support structure are used to maintain a fixed display state, then the display remains stationary during steering, but this increases device complexity
Solution Approach 1:
The adapter assembly serves multiple functions: it provides structural support for the display, enables rotational movement of the steering wheel, and maintains the display in a fixed position. By combining these functions into a single integrated component rather than using separate steering column and support structures, the patent reduces overall device complexity.
Solution Approach 2:
The adapter acts as an intermediary component between the steering wheel and the display mounting structure. It mediates the rotational movement of the steering wheel while keeping the display fixed, eliminating the need for complex steering column and support structures.
3Ease of manufacture
If the display is fixed to a rotating structure, then the display rotates with the steering wheel, but this makes the displayed information difficult to view
Solution Approach 1:
The mounting structure is segmented into a rotating steering wheel portion and a fixed display support portion connected through the adapter. This segmentation allows the display to be mounted on a simple structure while remaining stationary for easy viewing, avoiding the problem of rotation.
