Solution Overview

Problem

Existing shock absorber mounting seats have a large number of parts, leading to assembly inconveniences and low structural strength due to the use of a separate solenoid valve connected via a mounting housing, typically welded to the seat body.

Innovation Solution

A mounting seat for a shock absorber with an integrally formed mounting housing and seat body, incorporating a main flow channel and mounting cavity to accommodate an external solenoid valve, reducing parts and enhancing structural strength through symmetrical design and axial alignment of components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the solenoid valve is connected to the seat body through a separate mounting housing, then the solenoid valve can be fastened in the shock absorber, but the quantity of parts increases and assembly becomes inconvenient

Engineering Contradiction:
Improvesolenoid valve fasteningVSAvoidquantity of parts
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The mounting housing and seat body are integrated into a single integral structure, eliminating the need for separate mounting housing components and welding operations. The solenoid valve is directly mounted on the integrated seat body, reducing the total number of parts while maintaining the fastening function.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If the mounting housing is connected to the seat body by welding, then the solenoid valve can be fastened, but the structural strength of the mounting seat decreases

Engineering Contradiction:
Improvesolenoid valve fasteningVSAvoidstructural strength of mounting seat
Core Design Contradiction:
ReliabilityVSStrength

Solution Approach 1:

The mounting housing and seat body are formed as an integral structure through injection molding, eliminating welding joints that would compromise structural strength. The integral design ensures continuous material flow and uniform stress distribution, maintaining high structural strength while securing the solenoid valve.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of manufacture

If the mounting housing and seat body are separately connected by welding, then assembly is possible, but the manufacturing process becomes complex and time-consuming

Engineering Contradiction:
Improveassembly possibilityVSAvoidassembly efficiency
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The mounting housing and seat body are manufactured as a single integral component through injection molding, eliminating the need for separate welding operations. This reduces the number of manufacturing steps, decreases production time, and improves overall productivity while maintaining ease of manufacture.

Inventive Principle:
Principle #5Merging (Combining)

4Adaptability or versatility

If multiple separate components are used in the mounting seat, then the solenoid valve can be accommodated, but the structural integrity of the mounting seat is reduced

Engineering Contradiction:
Improvesolenoid valve accommodationVSAvoidstructural integrity
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The mounting housing and seat body are integrated into a single integral structure that provides stable structural composition. The integral design ensures consistent material properties throughout, eliminating weak points at joints while maintaining the ability to accommodate the solenoid valve through integrated mounting features.

Inventive Principle:
Principle #5Merging (Combining)
