Solution Overview

Problem

Existing adjustment elements for positioning vehicle attachments cause damage to structural components due to continuous stress, leading to corrosion and wear, especially when maintaining tight tolerances and alignments.

Innovation Solution

An adjustment element with a movably mounted contact section and hinge connection, allowing the support surface to pivot relative to the adjustment section, transferring forces as a surface load and compensating for manufacturing tolerances and warped components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If rigid connection elements are used to attach the attachment part to the structural part, then the attachment part is securely fixed, but the elements are damaged due to angular misalignment and force concentration

Engineering Contradiction:
Improvesecure fixationVSAvoidelement durability
Core Design Contradiction:
ReliabilityVSStrength

Solution Approach 1:

The adjustment element changes its geometric parameters (rotation angle and/or extension) to adapt to angular misalignment between the structural part and attachment part. This allows the rigid connection to be maintained while accommodating misalignment, preventing force concentration that would damage the elements.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The adjustment element introduces dynamic adaptability to the connection system by allowing rotation and/or extension. This dynamic capability enables the system to compensate for misalignment while maintaining secure fixation, resolving the contradiction between reliability and strength.

Inventive Principle:
Principle #15Dynamics

2Manufacturing precision

If the attachment part is positioned at a defined distance from the structural part, then proper spacing and alignment are achieved, but additional positioning mechanisms increase device complexity

Engineering Contradiction:
Improvepositioning accuracyVSAvoidpositioning mechanism complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The connection system is segmented into a structural part connection element, an adjustment element, and an attachment part connection element. This segmentation allows the adjustment element to specifically handle positioning and angular misalignment compensation, achieving precise positioning while keeping each component relatively simple.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The adjustment element acts as an intermediary between the structural part and attachment part. It provides the defined distance positioning and angular misalignment compensation without requiring complex positioning mechanisms in the other components, thus achieving manufacturing precision while limiting overall device complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Stress or pressure

If material-friendly force transmission is implemented, then the connection elements experience reduced stress, but the adjustment mechanism adds structural complexity

Engineering Contradiction:
Improveforce distributionVSAvoidadjustment mechanism complexity
Core Design Contradiction:
Stress or pressureVSDevice complexity

Solution Approach 1:

The adjustment element dynamically adapts its configuration (rotation and/or extension) to optimize force transmission paths. This dynamic adjustment distributes forces more evenly across the connection elements, reducing stress while maintaining a relatively simple mechanical structure compared to complex active control systems.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

By changing geometric parameters (angle and/or length) of the adjustment element, the force transmission characteristics are optimized. This passive parameter adjustment achieves material-friendly force distribution without requiring complex active control mechanisms, balancing stress reduction with structural simplicity.

Inventive Principle:
Principle #35Parameter changes
