Solution Overview

Problem

Existing support plates for valve bodies in internal combustion engines fail to maintain coaxial alignment of bearings, leading to potential valve blockage and inefficient fluid flow control, along with a lack of seal between the distributor and cylinder head, resulting in energy loss.

Innovation Solution

A support plate with a transverse groove and plane configuration, featuring aligned controlled and non-controlled pipe portions, a base armature with diametrically opposite bearings, and a control axis rod that maintains coaxial alignment and provides a seal between the cylinder head and distributor, ensuring consistent fluid flow and energy efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional support plate is used, then the structure is simple, but the bearings do not maintain coaxial alignment over time, leading to valve blockage and energy loss

Engineering Contradiction:
Improvebearing alignmentVSAvoidsupport plate structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The support plate is divided into a base armature and separately mounted valve bodies with control axes. The base armature contains pipe portions with recesses that receive and position the valve bodies, allowing independent alignment of bearing components while maintaining overall structural integrity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The base armature is pre-formed with recesses and bearing portions positioned in correct alignment before the valve bodies are mounted. This preliminary positioning ensures that when valve bodies are installed, the bearings are automatically coaxially aligned, preventing future misalignment and valve blockage.

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If valve bodies are mounted in conventional support plates, then assembly is simple, but the control axis and bearings fail to maintain coaxial alignment, causing valve blockage

Engineering Contradiction:
Improvecoaxial alignmentVSAvoidassembly process
Core Design Contradiction:
Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The base armature serves as an intermediary component between the support plate structure and the valve bodies. It provides recesses that act as positioning intermediaries, ensuring precise coaxial alignment of bearings and control axes during assembly without requiring complex alignment procedures.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention introduces a vertical dimension to the assembly process by using recesses in the base armature that receive valve bodies from above. This allows precision alignment to be achieved through vertical positioning rather than complex horizontal alignment, simplifying the manufacturing process while maintaining high precision.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Loss of energy

If known support plates are used, then the device is simple, but there is no seal between the distributor and cylinder head, resulting in energy loss

Engineering Contradiction:
Improvefluid leakageVSAvoidsupport plate design
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The sealing function is merged with the structural support function. The base armature is designed with surfaces that simultaneously provide structural support and create sealing contact between the distributor and cylinder head, eliminating the need for separate sealing components while preventing energy loss through leakage.

Inventive Principle:
Principle #5Merging (Combining)
