Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vehicle operating devices with inclined display surfaces are not suitable for all applications, particularly on vehicles with higher frames, leading to difficulty in reading the display and hazardous situations for operators, who may need to climb or use aids for better visibility.
Innovation Solution
A vehicle operating device with detachable brackets that allow the display angle to be changed between 30° to 90° relative to the horizontal, enabling flexible mounting positions without complex constructions, and featuring symmetrical mounts for easy swapping and hidden locking elements to prevent theft.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the operating and display device is mounted at a higher position on the vehicle, then the mounting position flexibility is improved, but the readability and visibility of the display deteriorates
Solution Approach 1:
The patent applies the dynamics principle by making the display angle adjustable through interchangeable brackets. The display device can dynamically change its orientation angle (e.g., between 30-60 degrees and 70-90 degrees relative to horizontal) to adapt to different mounting positions and operator needs, resolving the contradiction between mounting flexibility and readability.
Solution Approach 2:
The patent changes the geometric parameter of the display angle by providing different brackets with specific angle configurations. By swapping brackets, the display surface angle relative to the horizontal plane is modified, allowing optimization of visibility while maintaining high mounting positions.
2Ease of operation
If the display surface is inclined at a steeper angle, then the visibility and glare reduction is improved, but the mounting position options are restricted
Solution Approach 1:
The interchangeable bracket system enables dynamic adjustment of the display angle. Operators can switch between different angle configurations (e.g., moderate incline for general use, steeper incline for glare reduction) depending on mounting position and environmental conditions, thus maintaining both visibility improvement and mounting flexibility.
Solution Approach 2:
The mounting system is segmented into separate interchangeable brackets that can be independently selected and swapped. This segmentation allows the display device to be coupled with different angle-specific brackets, providing multiple mounting position options while maintaining the ability to optimize for visibility and glare reduction.
3Device complexity
If fixed mounting brackets are used, then the device structure is simplified, but the adaptability to different vehicle types and positions is reduced
Solution Approach 1:
The bracket system is designed with universal compatibility, where a set of standardized brackets can be used across different vehicle types and mounting positions. Each bracket serves multiple potential mounting scenarios, and the ability to swap brackets provides multi-functionality without requiring completely different mounting systems for each application.
Solution Approach 2:
The mounting system is divided into separable bracket components that can be independently selected based on specific vehicle and application requirements. This segmentation maintains relatively simple individual bracket structures while providing collective adaptability through the bracket set, resolving the contradiction between structural simplicity and versatility.

AI summary
The invention relates to a vehicle control device with an operating and display unit (32) for performing control functions on the vehicle. To improve its operability, a first bracket (34) and a second bracket (74) are provided, which can be detachably connected to the operating and display unit (32) on its right and left sides, respectively. For this purpose, a first positioning and connection device (68) associated with the right side and a second positioning and connection device (79) associated with the left side are provided, wherein the operating and display unit (32) can be mounted at two different display angles (α, β) by interchanging the two brackets (34, 74). Furthermore, the invention relates to a method for changing the display angle of an operating and display unit of such a vehicle control device that is mounted or to be mounted on the vehicle.
