Agricultural Vehicle Display Instrument Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display instruments for agricultural vehicles are inefficient in verifying safety and legally required operating variables during changes, as they must ensure the correct display of multiple parameters, which is time-consuming and requires verification of all parameters upon any operational change, and are not adaptable to different types of vehicles with minimal effort.
Innovation Solution
A display instrument with divided display areas, where one driver handles safety and legally required operating variables and another handles performance variables specific to the implement, ensuring that changes to one group do not affect the other, allowing for independent operation and adaptation to different vehicle types with reduced verification needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single driver displays multiple operating variables on one display area, then the display instrument can show comprehensive operating parameters, but verification effort increases when changes are made
Solution Approach 1:
The display area is divided into first and second partial areas, with the first driver handling safety and legally required operating variables while the second driver handles performance variables. This segmentation allows independent verification of each driver, reducing overall verification time when changes are made to one group of variables.
2Device complexity
If a single driver handles all operating variables, then the display instrument structure is simple, but any change requires verification of all parameters
Solution Approach 1:
The display instrument is segmented into two independent drivers, each handling specific groups of operating variables. This maintains relatively simple individual driver structures while improving verification efficiency, as changes to one driver do not require verification of the other.
3Ease of operation
If operating variables are grouped together in one driver, then the display instrument is easier to operate, but adaptability to different vehicle types is reduced
Solution Approach 1:
The display is segmented into two partial areas with specialized drivers: the first driver handles universal safety and legally required variables that are common across all agricultural vehicles, while the second driver handles performance variables specific to particular vehicle types or implements. This segmentation maintains ease of operation for critical variables while enabling adaptability through independent configuration of the second driver.
4Area of stationary object
If all operating variables are displayed on one screen, then the display area utilization is high, but safety verification is compromised during changes
Solution Approach 1:
The display area is segmented into two distinct partial areas, with the first driver exclusively handling safety and legally required operating variables. This segmentation ensures that safety-critical variables maintain dedicated display space and independent verification, preventing compromise of safety reliability even when the second driver is modified or when display area utilization needs to be optimized.

AI summary
A display instrument for showing several operating parameters for an agricultural vehicle has a display area which is divided into a first (15) and a second sub-area (16), a first driver (30) for converting supplied values of a first plurality of operating parameters to be displayed into a graphic displayed on the first sub-area (15) and a second driver (31) which receives values of a second plurality of the operating parameters and displays a graphic generated therefrom on the second sub-area (16).
