Solution Overview

Problem

Existing oil additive injection devices face issues with sludge buildup and flow resistance due to their design, which affects the effectiveness of lubricant additives in equipment like internal combustion engines and hydraulic systems.

Innovation Solution

A lubricant additive injection system featuring a series of tubular injectors with partially permeable membranes and a delivery piston that compresses additives for controlled release into the lubricant, minimizing sludge accumulation and flow resistance through a circular or spiral pattern arrangement and integration with a lubricant distribution manifold.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a delivery piston is used to force additive through a porous sidewall, then additive dispersion is improved, but sludge buildup increases

Engineering Contradiction:
Improveadditive dispersionVSAvoidsludge buildup
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The delivery piston is segmented into multiple smaller pistons arranged in a circular array, each forcing additive through a separate porous sidewall section. This segmentation prevents sludge accumulation by eliminating dead zones and improving flow distribution across the additive reservoir.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The additive reservoir and delivery piston are designed with curved, circular geometries rather than flat or angular shapes. This curvature eliminates corners and crevices where sludge could accumulate, while maintaining effective additive dispersion through the porous sidewall.

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Reliability

If a porous sidewall is used for additive release, then additive transfer is improved, but flow resistance increases

Engineering Contradiction:
Improveadditive transferVSAvoidflow resistance
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The porous sidewall is positioned at the optimal location where it receives maximum pressure from the delivery piston, creating a localized high-efficiency additive transfer zone. This concentrated approach improves additive transfer while minimizing the overall surface area requiring porous material, thereby reducing flow resistance.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The porosity parameters of the sidewall are optimized to balance additive transfer efficiency with flow resistance. By adjusting pore size, pore density, and thickness of the porous material, the system achieves effective additive release while maintaining acceptable lubricant flow characteristics.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If multiple dispensing chambers are arranged in a circular pattern, then additive distribution is improved, but device complexity increases

Engineering Contradiction:
Improveadditive distributionVSAvoidstructural complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Multiple dispensing chambers are merged into a single integrated additive reservoir with a circular array of delivery pistons. This consolidation maintains uniform additive distribution across all dispensing points while reducing the number of separate components, thereby lowering overall device complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The circular array of delivery pistons serves multiple functions simultaneously: it distributes additive uniformly across the porous sidewall, maintains structural integrity of the reservoir, and facilitates easy assembly and disassembly of the filter element. This multi-functionality reduces the need for additional specialized components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A lubricant additive dispensing apparatus comprising a tubular housing extending between a fluid supply side and a fluid discharge side, wherein each side is sealed by a respective end wall. A volume of fluid additive is stored within a fluid additive storage cavity formed within the tubular housing. Fluid enters the lubricant additive dispensing apparatus, wherein a first portion of the fluid passes therethrough and a second portion of the fluid is directed towards a piston cap attached to a compression spring. The second fluid portion applies a compression force to the piston, interacting with the generated expansion force of the spring to cause the piston cap to oscillate. The piston cap is in communication with the fluid additive, applying an oscillating pressure thereto, causing a controlled volumetric rate of dispensing of the additive into the fluid.
