Solution Overview

Problem

Existing vacuum pump designs for vehicles lack a robust and compact mounting system that effectively dampens forces from the vehicle framework while ensuring secure attachment and easy inspection of dampers, leading to potential movement and vibration issues.

Innovation Solution

A vacuum pump mounting assembly with a built-in mounting bracket that encompasses all solid structures and dampers, featuring a reception for each damper and an inspection window, providing a rigid structure with separable dampers and a clamp-connection for secure fastening and easy inspection, while allowing for various damper types and materials.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If dampers with high shore hardness are used to securely fasten the vacuum pump to the framework, then the mounting structure becomes more rigid and secure, but the decoupling effect is reduced and more forces are transmitted to the pump

Engineering Contradiction:
Improvemounting strengthVSAvoidforce transmission
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The mounting bracket integrates multiple functions: it provides structural support, encompasses all dampers within a single housing, and creates a rigid overall structure. This merging of functions allows the use of softer dampers while maintaining mounting security through the integrated bracket structure.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The mounting bracket is designed to encompass all dampers within its structure, with each damper received in a dedicated reception area. This nesting arrangement allows the dampers to be softer while the outer bracket provides the necessary rigidity and security.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Stability of the object's composition

If the mounting assembly structure is made more rigid to securely fasten the vacuum pump, then attachment security is improved, but the decoupling effect of dampers is reduced

Engineering Contradiction:
Improvemounting stabilityVSAvoidforce transmission
Core Design Contradiction:
Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The mounting bracket combines structural support and damper housing functions into a single integrated component. This allows the bracket itself to provide rigidity and stability while the softer dampers inside provide force decoupling.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The mounting bracket acts as an intermediary structure that separates the rigid mounting requirements from the flexible damping requirements. It provides a stable mounting interface while containing the softer dampers that decouple forces.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of manufacture

If dampers are made as separate parts for simplified production, then manufacturing ease is improved, but assembly complexity increases

Engineering Contradiction:
Improvedamper productionVSAvoidassembly complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The mounting bracket is designed with integrated receptions that accommodate separate damper components. This nesting design allows dampers to be manufactured separately for simplicity while the bracket's pre-designed receptions guide their assembly, reducing overall complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)

4Volume of moving object

If the mounting bracket encompasses all dampers and solid structures, then a compact design is achieved, but inspection difficulty increases

Engineering Contradiction:
Improvemounting assembly volumeVSAvoiddamper inspection
Core Design Contradiction:
Volume of moving objectVSDifficulty of detecting and measuring

Solution Approach 1:

The mounting bracket incorporates transparent or translucent sections at the damper reception areas. This allows the dampers to be visually inspected for proper installation and condition without disassembling the compact mounting assembly, maintaining both compactness and inspectability.

Inventive Principle:
Principle #32Color changes
