Commercial Vehicle Cab Rotary Function Column for Item Accessibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercial vehicle drivers face challenges in efficiently and neatly arranging various personal and work-related items within the driver's cab due to limited space and the need for quick setup during rest periods or vehicle changes, often requiring multiple trips and cumbersome handling of items.
Innovation Solution
A rotary function column system with a central axis of rotation allows for 360-degree rotation, enabling easy access and arrangement of items between the driver's and passenger seats, combined with telescopic extensions and pivoting arms for flexible storage and display solutions, enhancing mechanical stability and usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If items are loaded from the passenger side due to steering wheel obstruction, then accessibility is improved, but the passenger seat becomes a hindrance requiring items to be lifted over it
Solution Approach 1:
A telescopic loading arm with central pivot point acts as an intermediary mechanism, extending across the passenger seat to deliver items directly to the storage area between driver and passenger seats, eliminating the need to lift items over the seat
2Quantity of substance
If multiple trips are made between storage location and cab, then all necessary items can be brought inside, but time and effort are significantly increased
Solution Approach 1:
The telescopic loading arm dynamically extends and retracts to accommodate different loading scenarios, allowing large items to be reached from outside the cab while smaller items can be accessed from inside, enabling all items to be loaded in a single trip
Solution Approach 2:
The loading arm's length parameter is variable, allowing it to reach items stored outside the cab while maintaining a compact form when retracted, enabling flexible access to items at different distances without requiring multiple trips
3Strength
If the cabin height is maintained at structurally determined levels, then structural integrity is preserved, but bringing heavy items inside becomes difficult
Solution Approach 1:
The telescopic loading arm serves as a mechanical intermediary that bridges the height gap, allowing items to be delivered to the storage area without requiring manual lifting over the cabin's structural height barrier
4Adaptability or versatility
If a sleeping berth is added to the rear of the cab, then accommodation capability is improved, but remaining space for item arrangement becomes limited
Solution Approach 1:
The loading arm operates in a third dimension by extending horizontally across the cabin space above the sleeping berth area, utilizing vertical clearance rather than horizontal floor space, thereby enabling item delivery without encroaching on the sleeping area
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates efficient, space-saving, and orderly arrangement of items within the cab, reducing the need for multiple trips and improving accessibility, even during vehicle movement, while maintaining structural integrity under varying conditions.
Implementation Method 1
a first axis of rotation (27a), which extends within the cab, with an angle formed between a first longitudinal axis (29) of the first axis of rotation (27a) and the orientation of the floor surface (30). The first axis of rotation (27a) forms a shaft which is rotatably mounted relative to the floor surface (30) by at least two rolling bearings
