Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lubricant supply systems for single-track motor vehicles face challenges due to restricted installation spaces, leading to long distances between components, increased energy expenditure, and longer start times, which result in increased wear and environmental inefficiencies.
Innovation Solution
A lubricant supply system with a lubricant filter directly attached to the lubricant pump, or with a pump shaft continuation crossing the filter, or with two lubricant pumps driven by a common pump shaft, to minimize distances and reduce energy losses and lubricant volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the lubricant filter is positioned far from the lubricant pump due to restricted installation spaces, then the installation space is utilized, but the line distance increases causing increased energy expenditure and power losses
Solution Approach 1:
The patent merges the lubricant filter with the lubricant pump by directly attaching the filter housing to the pump housing, creating an integrated assembly. This eliminates the need for separate mounting locations and long connecting lines, thereby reducing line distance and power losses while efficiently utilizing the limited installation space in single-track motor vehicles.
2Adaptability or versatility
If the line distance between lubricant pump and lubricant filter is long, then installation flexibility is improved, but the required volume of lubricant increases leading to environmental deficiencies
Solution Approach 1:
By integrating the lubricant filter directly onto the lubricant pump housing, the patent minimizes the volume of lubricant required in the line system. This merged design eliminates long line distances and reduces the overall lubricant inventory needed, addressing environmental concerns while maintaining installation flexibility through the compact integrated unit.
3Adaptability or versatility
If the line distance is long, then component placement flexibility is improved, but the start time for lubricant supply increases causing increased wear
Solution Approach 1:
The direct attachment of the lubricant filter to the lubricant pump creates the shortest possible line distance, enabling immediate lubricant supply upon engine start-up. This integrated design eliminates delays associated with long line distances while preserving component placement flexibility through the compact self-contained unit.
4Adaptability or versatility
If multiple lubricant pumps are provided for different engine components, then lubrication coverage is improved, but the device complexity and installation space requirements increase
Solution Approach 1:
The patent integrates multiple lubricant pumps within a single housing that also contains the lubricant filter. This merged design provides comprehensive lubrication coverage for different engine components while reducing system complexity compared to having separate pump assemblies. The integrated unit eliminates multiple mounting locations and simplifies the overall lubrication system architecture.
