Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drive devices generate waste heat and require complex production processes due to multi-piece configurations, which complicate sealing and efficiency.
Innovation Solution
A single-piece metal distributor block with a continuous longitudinal bore and transverse bores, integrated oil pump, valve control, and sensor attachment, allowing for simplified production and enhanced tightness and oil distribution within the gear unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a multi-piece configuration is used for the distributor block, then flexibility in assembly is improved, but manufacturing complexity and sealing requirements increase
Solution Approach 1:
The distributor block is produced as a single-piece component from metal material, integrating multiple functions into one monolithic structure. This eliminates the need for separate parts and sealing elements, simultaneously simplifying production and ensuring high tightness without leakage risks associated with multi-piece assemblies.
2Reliability
If a single-piece distributor block is used, then tightness is improved, but manufacturing complexity increases
Solution Approach 1:
The distributor block is produced as a single-piece component from metal material, integrating multiple functions into one monolithic structure. This eliminates the need for separate parts and sealing elements, simultaneously simplifying production and ensuring high tightness without leakage risks associated with multi-piece assemblies.
3Device complexity
If oil is supplied without a valve, then the system is simpler, but oil flow control capability is reduced
Solution Approach 1:
A valve is integrated directly into the distributor block, allowing the oil distribution system to control its own flow automatically based on operational needs. The valve enables the system to self-regulate oil distribution to different gear units without requiring external control mechanisms, maintaining simplicity while providing adaptability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates simple and efficient production with high tightness, controlled oil distribution, and easy sensor integration, improving the overall performance and reliability of the drive device.
Implementation Method 1
an oil pump, in particular an oil pump driven by an electric motor, supplies oil from the oil sump of the gear unit into a first opening of the longitudinal bore
Implementation Method 2
a valve for interrupting the oil flow from the longitudinal bore to the first transverse bore is arranged in the distributor block
