Agricultural Vehicle Ballasting Menu System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complex selection of ballasting weights for agricultural vehicles is challenging due to multiple influencing parameters, requiring extensive knowledge from operators, and existing systems either overload operators with data or provide vague recommendations, especially for untrained users.
Innovation Solution
A method and system that present users with a menu of implement identifiers to select operational parameters, allowing derivation of optimal ballasting options based on predetermined criteria, incorporating tolerance for unknown factors like ground hardness, using a programmable device with a data processing system and user-operable input means to simplify the selection process.

Engineering Contradiction Analysis
1Measurement precision
If a system automatically requests parameters from the operator, then ballasting recommendations can be more accurate, but the operator is overloaded with data entry requirements
Solution Approach 1:
The system performs preliminary actions by storing default parameter values and implement characteristics in advance. When an operator selects an implement type, the system retrieves pre-stored data about that implement's typical parameters, eliminating the need for operators to manually enter all parameters from scratch.
Solution Approach 2:
The system serves itself by automatically retrieving and populating parameter data from its own stored database when an implement is selected. The system uses the selected implement identifier to automatically fetch associated parameters, reducing reliance on operator knowledge and manual data entry.
2Ease of operation
If sensors are used to determine operational parameters automatically, then operator input requirements are reduced, but system cost increases significantly
Solution Approach 1:
Instead of using physical sensors to measure parameters, the system creates and uses digital copies of parameter data stored in its database. The implement identifier serves as a key to retrieve copied data about typical operating parameters for that implement type, providing a cost-effective alternative to physical sensing.
Solution Approach 2:
The system uses inexpensive data structures and software tables to store parameter information instead of expensive physical sensors. The parameter data is essentially disposable information that can be stored, retrieved, and discarded without physical hardware costs.
3Ease of operation
If standalone offline systems use average values for parameters, then the system is simple to operate, but ballasting recommendations become vague
Solution Approach 1:
The system segments parameter data by implement type, storing different parameter ranges and characteristics for different implements (ploughs, seed drills, sprayers, etc.). This allows the system to provide specific recommendations tailored to each implement type rather than using generic average values for all implements.
Solution Approach 2:
The system applies local quality by storing and retrieving parameter data specific to each implement type and its local operating conditions. Each implement has its own characteristic parameter ranges stored in the database, allowing the system to provide locally-optimized recommendations rather than universal averages.

AI summary
A method and system for assisting user selection of one from a plurality of available ballasting options for an agricultural vehicle when coupled to an agricultural implement. The user is presented with a selection menu (16) of implement types, whereby each implement type (R2.1, R2.2) defines operating ranges of discrete values for first, second and optionally third operational parameters of the vehicle, with the differing combinations defining a values subset. An optimal choice from the available ballasting options is made for each combination in the values subset, and a selection from the optimal choices based on prevalence or probability of occurrence is made and may be presented (17) to the user. Operational parameters may include operating speed, loading due to implement weight and engine power.
