Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lubrication systems for utility vehicles require higher-level vehicle electronics for ease of operation and program selection, which is unnecessary for most customers, and lack automatic lubrication capabilities with multiple programs.
Innovation Solution
A self-contained lubrication system with a direct connection to an input and display device in the driver's cabin, allowing switching between lubrication programs and initiating intermediate lubrication independently of higher-level electronics, using a microprocessor and simple push-button operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If higher-level vehicle electronics are integrated into the lubrication system, then ease of operation and diagnostic functions are improved, but device complexity and cost increase
Solution Approach 1:
The lubrication system is segmented into independent functional modules: a control unit with microprocessor for lubrication control, a separate display unit for user interaction, and basic vehicle electronics for power supply. This segmentation allows the lubrication system to operate independently without requiring complex integrated vehicle electronics, resolving the contradiction between ease of operation and device complexity.
Solution Approach 2:
The control unit includes an integrated microprocessor that autonomously manages lubrication programs, monitoring, and control without requiring external higher-level vehicle electronics. The system serves itself by storing multiple lubrication programs internally and automatically selecting and executing them based on operational conditions, eliminating the need for complex external electronic systems while maintaining ease of operation.
2Adaptability or versatility
If multiple lubrication programs are stored in the control unit, then adaptability to different operating conditions is improved, but device complexity increases
Solution Approach 1:
The control unit is designed as a universal multi-functional device that stores and executes multiple lubrication programs (e.g., different cycle times, lubrication quantities, and intervals) within a single integrated microprocessor. This allows the system to adapt to various operating conditions (normal operation, cold weather, heavy loads) without requiring separate control units or complex external electronics, resolving the contradiction between adaptability and device complexity.
3Ease of operation
If a direct connection is made between the lubricating unit and input/display device, then ease of operation and error reduction are improved, but device complexity increases
Solution Approach 1:
The display unit is directly connected to the control unit, merging the user interface and control functions into an integrated system. This direct connection eliminates the need for intermediate vehicle electronics or complex communication protocols, allowing the driver to easily select lubrication programs and monitor system status while reducing potential error sources. The merged design maintains simplicity despite the direct connection.

AI summary
A lubrication system for a utility vehicle with a lubricating unit having a lubricant reservoir, a pump, and a distributor attached thereto to which supply lines to a plurality of lubrication points can be attached, and comprising a control module having at least two lubrication programs stored therein, wherein the pump initiates an ejection of grease in a cycle predetermined by the respective lubrication program. The object of the invention is to improve upon a lubrication system such that a change between lubrication programs and optionally the execution of an intermediate lubrication using an automatic lubrication system is possible during driving operations independent of the presence of a higher level on-board electronics system. The object is accomplished in that the lubricating unit is connected directly to an input and display device disposed in the vehicle or at other accessible places on the vehicle, the input and display device used to switch between lubrication programs and to initiate an intermediate lubrication.
