Modular Lubricant Distributor Injector Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lubricant distributors face challenges in quickly replacing individual injectors due to their integration with the distributor plate, making it difficult to maintain and upgrade the system efficiently.
Innovation Solution
Designing a lubricant distributor with injectors that have their own housing, allowing for easy attachment and detachment from a distributor plate, where the inlet and outlet connections are arranged on one side or end of the housing, enabling quick replacement and facilitating a high density of injectors on the plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If injectors are formed directly in the distributor plate, then the structure is compact and integrated, but individual injectors cannot be quickly replaced and interchangeability is poor
Solution Approach 1:
The distributor is divided into separate functional modules: the distributor plate and individual injectors. Each injector is a separate component that can be independently attached to or removed from the distributor plate, enabling selective replacement without replacing the entire distributor system.
Solution Approach 2:
The distributor plate is designed with standardized connection interfaces that can accommodate multiple types of injectors. The plate includes through-holes and connection means that work with different injector configurations, allowing the same distributor plate to support various injector types for different lubrication requirements.
2Device complexity
If injectors are integrated into the distributor plate, then the overall structure is simplified, but the density of injectors that can be arranged is limited
Solution Approach 1:
The connection interfaces on the distributor plate are arranged in multiple dimensions and orientations. Through-holes are positioned at various locations and angles on the plate surface, allowing injectors to be arranged in dense configurations without interfering with each other, thereby increasing the number of injectors that can be accommodated.
3Adaptability or versatility
If injectors have connections on multiple sides, then connectivity is improved, but assembly and disassembly become more complex
Solution Approach 1:
The connection functionality is extracted from the injector body and implemented as separate connection means (threaded holes, quick-connect interfaces) on both the distributor plate and injector housings. This separation allows for standardized, tool-free or minimal-tool connection and disconnection operations while maintaining flexible connectivity options.
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
This design allows for simple and rapid assembly and disassembly of injectors, reducing downtime and improving the overall interchangeability of the lubricant distributor, enabling efficient lubrication distribution with a large number of replaceable injectors.
Implementation Method 1
the piston (10) is displaced by the lubricant pressure (p) against the force of the spring (19)
Implementation Method 2
the piston (10) is pushed back into its starting position by the spring force of the spring (19)
Implementation Method 3
a check valve (12) which allows the lubricant to flow from the lubricant inlet (11) into the first chamber (9a) and which blocks a flow of lubricant from the first chamber (9a) to the lubricant inlet (11)

AI summary
The invention relates to a lubricant distributor having a distribution plate (1, 21) and at least one injector (2, 22) that can be connected thereto, which is formed by a housing (8, 28) that defines a longitudinal axis, having an inlet (11, 31) and an outlet (14, 34) that are connected to corresponding connections in the distribution plate, and a metering and switching unit configured in the housing, wherein the inlets and outlets are disposed on the side of the housing that faces the distribution plate.
