Solution Overview

Problem

Existing vehicle body part gripping systems are inflexible and require redesign when the body part evolves, limiting adjustment and repair capabilities, and often necessitate specific complementary parts for proper mounting.

Innovation Solution

A modular gripping system with adjustable structural beams, mooring means, and multi-axis gripping tool support mechanisms, allowing sliding, rotational adjustments of the base and tool holder, enabling quick adaptation to different body part geometries with a minimal number of components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a gripping system is designed for a specific body part, then the gripping performance is optimized, but the system cannot be adapted when the body part evolves and requires complete redesign

Engineering Contradiction:
Improveadaptability to different body partsVSAvoidsystem redesign requirement
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The gripping system is divided into modular components: beams with notches, adjustable support means, and gripping tools. Each component can be independently selected and reconfigured, allowing the system to adapt to different body parts without complete redesign. The support means can be detached and repositioned to different notches on the beams.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The beams are designed with multiple notches at regular intervals that can accommodate various support means positions. The same beam structure can serve multiple body part configurations, making the system universal rather than specific to one body part geometry.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If gripping systems use notches at regular intervals for positioning, then mounting is simplified, but the adjustment precision is limited

Engineering Contradiction:
Improvemounting simplicityVSAvoidposition adjustment precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The support means incorporates adjustable elements that can be positioned continuously along the beam length, not just at fixed notches. This dynamic adjustment capability allows precise positioning while maintaining ease of operation through simple mechanical adjustment mechanisms.

Inventive Principle:
Principle #15Dynamics

3Device complexity

If gripping systems have limited adjustment capabilities, then the structure remains simple, but complementary parts are needed for proper mounting

Engineering Contradiction:
Improvenumber of componentsVSAvoidmounting flexibility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The support means is designed as a universal component that can be mounted on any beam and adjusted to various positions and orientations. This multi-functional design eliminates the need for body part-specific complementary mounting parts, as the same support means can accommodate different tool types and positions.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The support means is segmented into adjustable components that can be independently positioned. This segmentation allows the system to achieve complex mounting configurations using a limited set of standardized parts rather than requiring specific complementary parts for each application.

Inventive Principle:
Principle #1Segmentation

4Device complexity

If the gripping system uses fixed tool positions, then the design is simpler, but the system cannot adapt to different body part geometries

Engineering Contradiction:
Improveadjustment mechanism complexityVSAvoidgeometric adaptation capability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The support means incorporates multiple degrees of freedom with adjustable elements that can be positioned independently along different axes. This dynamic configuration allows the tool holder to reach various positions and orientations to accommodate different body part geometries while using a standardized adjustment mechanism.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The support means provides adjustment in multiple spatial dimensions: longitudinal position along the beam, lateral position perpendicular to the beam, and rotational orientation. This multi-dimensional adjustability enables geometric adaptation without increasing the fundamental complexity of the adjustment mechanism.

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