Solution Overview

Problem

Existing filter devices for liquid filtration in motor vehicles lack a secure and structurally simple method to attach to receiving components, risking damage from strong clamping forces and vibrations.

Innovation Solution

A filter device with a clamping bracket that engages around the filter housing, featuring a swiveling hinge coupling between a clamp and clamping collar, allowing for adjustable tension and a positive connection via a projection and engagement window, which transfers clamping force without overloading the hinge, ensuring secure attachment and reduced risk of damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a clamping bracket is used to secure the filter device, then the attachment reliability is improved, but the risk of damage from strong clamping forces increases

Engineering Contradiction:

Improveattachment reliabilityVSAvoiddamage from clamping forces

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a receiving component as an intermediary element between the clamping bracket and the filter housing. The clamping bracket attaches to the receiving component, which in turn secures the filter housing. This mediator distributes and reduces the clamping forces, preventing direct transmission of strong forces to the filter housing that could cause damage, while still maintaining secure attachment.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The attachment system is divided into separate functional components: the clamping bracket for applying clamping force, the receiving component for distributing forces, and the filter housing for filtration. This segmentation allows each component to perform its specific function optimally while protecting the filter housing from excessive forces.

Inventive Principle:

Principle #1Segmentation

2Stability of the object's composition

If a rigid clamping connection is used, then the attachment stability is improved, but the vulnerability to vibration-induced damage increases

Engineering Contradiction:

Improveattachment stabilityVSAvoidvibration-induced damage

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The patent employs a flexible membrane as part of the sealing and connection system. This flexible element can accommodate vibrations and dynamic movements while maintaining the seal and connection integrity. The flexibility absorbs vibration energy, preventing rigid force transmission that could lead to vibration-induced damage, while still providing stable attachment.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The receiving component and flexible membrane act as cushioning elements that are built into the attachment system in advance. These elements are designed to absorb and dissipate vibration forces before they can transmit to the filter housing, providing protection against vibration-induced damage while maintaining stable attachment.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

3Reliability

If a complex fastening mechanism is used, then the attachment security is improved, but the structural simplicity is reduced

Engineering Contradiction:

Improveattachment securityVSAvoidstructural simplicity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The clamping bracket is designed with dynamic capabilities, allowing it to be easily attached and detached. The bracket can be opened to place onto the filter housing and then closed to secure it, providing simple operation. This dynamic design maintains attachment security while avoiding complex fastening mechanisms, enabling easy installation and removal.

Inventive Principle:

Principle #15Dynamics
