Innovation Solution

A movable fixture with a tilted design that uses gravity to secure laminates during stacking and transport, eliminating the need for additional securing devices like clamping assemblies, while allowing easy handling and transport of the laminates.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a horizontally mounted fixture is used to stack laminates, then the laminates can be stacked vertically within the fixture, but a clamping assembly must be assembled and disassembled during transport, which is time-consuming and increases manufacturing costs

Engineering Contradiction:
Improvestability of laminate stackingVSAvoidtime for assembling and disassembling clamping assembly
Core Design Contradiction:
Stability of the object's compositionVSLoss of time

Solution Approach 1:

The fixture is designed to be movable rather than stationary, allowing it to be transported with the laminates without requiring clamping assemblies. The fixture can be moved between stacking position and transport position, eliminating the need for additional securing devices during transport.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The fixture serves multiple functions: it provides a stable stacking surface for assembling laminates and simultaneously serves as a transport container. This multi-functionality eliminates the need for separate clamping assemblies, as the fixture itself secures the laminates during both stacking and transport operations.

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

2Stability of the object's composition

If a horizontally mounted fixture is used, then laminates can be stacked vertically, but the fixture cannot be used for transport without additional clamping assemblies

Engineering Contradiction:
Improvestacking stabilityVSAvoidcomplexity of fixture and clamping assembly system
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The fixture is designed to perform both stacking and transport functions with a single structure. The tilted configuration allows the fixture to securely hold laminates during transport without requiring additional clamping assemblies, thereby reducing device complexity while maintaining stability.

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

Solution Approach 2:

The fixture transitions from a horizontal stacking configuration to a tilted transport configuration. This parameter change in orientation allows the fixture to securely hold laminates during transport using gravity and friction, eliminating the need for complex clamping assemblies.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If a tilted fixture is used to eliminate clamping assemblies, then transport efficiency improves, but the fixture design becomes more complex

Engineering Contradiction:
Improvetransport efficiencyVSAvoidfixture design complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The fixture incorporates a tilted configuration that changes the orientation of the stacking surface. This parameter change allows the fixture to securely hold laminates during transport through gravity and friction alone, eliminating the need for complex clamping assemblies while improving transport efficiency.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The fixture is designed with movable components that allow it to transition between horizontal stacking position and tilted transport position. This dynamic capability enables the fixture to adapt to different operational requirements without requiring separate fixtures for stacking and transport.

Inventive Principle:
Principle #15Dynamics

AI summary

A movable fixture onto which core laminates may be stacked in a manner such that the laminates are secure and easily accessible, and the fixture may be used to transport the laminates. The fixture consists of, among other things, a stacking table that has at least one pivot arm extending therefrom and a base plate that has at least one appendage extending therefrom. The pivot arm is movably and removably attached to the appendage in order to permit the stacking table to move between a transporting position and an assembling position.
