Solution Overview

Problem

Conventional tooling fixtures are heavy, bulky, and inflexible, requiring substantial capital equipment for movement and storage, occupying large spaces, and being difficult and expensive to repair or modify for design changes.

Innovation Solution

A modular tooling assembly with a base, releasably coupled frames, and a panel secured by a vacuum system, allowing for quick reconfiguration by changing sets of frames and panel interchangeability, enabling support of various contours and profiles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If conventional tooling fixtures are used, then structural stability is maintained, but weight increases and mobility decreases

Engineering Contradiction:
Improvestructural stabilityVSAvoidfixture weight
Core Design Contradiction:
Stability of the object's compositionVSWeight of moving object

Solution Approach 1:

The fixture is divided into modular components including a base, multiple frames that can be selectively coupled, and interchangeable panels. Each frame includes support members with positioning features, allowing the system to maintain stability through proper modular assembly while reducing overall weight compared to conventional integral fixtures.

Inventive Principle:
Principle #1Segmentation

2Strength

If conventional integral tooling is used, then structural rigidity is maintained, but adaptability for design changes decreases

Engineering Contradiction:
Improvestructural rigidityVSAvoiddesign change adaptability
Core Design Contradiction:
StrengthVSAdaptability or versatility

Solution Approach 1:

The fixture transitions from a static integral structure to a dynamic reconfigurable system. Frames can be selectively coupled and decoupled from the base, and panels can be interchanged between frames. Positioning features on support members allow adjustment of frame positions, enabling the system to adapt to different design requirements while maintaining structural rigidity when assembled.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If multiple conventional tools are stored, then part fabrication capability is maintained, but storage space requirements increase

Engineering Contradiction:
Improvepart fabrication capabilityVSAvoidstorage space
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The modular fixture system serves multiple functions through a single base and frame set. By interchanging panels between frames and reconfiguring frame positions on the base, the system can fabricate multiple different parts without requiring separate dedicated fixtures for each part type, significantly reducing storage space requirements.

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

4Adaptability or versatility

If conventional tooling is modified for design changes, then functionality is updated, but repair and modification costs increase

Engineering Contradiction:
Improvefunctionality updateVSAvoidmodification cost
Core Design Contradiction:
Adaptability or versatilityVSEase of repair

Solution Approach 1:

The fixture is segmented into interchangeable panels and reconfigurable frames. When design changes are required, only the specific panel needing modification must be replaced or adjusted, rather than modifying the entire fixture. This reduces modification costs and simplifies repair operations.

Inventive Principle:
Principle #1Segmentation

AI summary

A tooling assembly is provided, for use with a panel defining a tool-side surface and the tool-side surface defining a profile. The tooling assembly includes a base (20), a plurality of support members (28) fixedly attached to the base (20), a plurality of frames (22) each defining a corresponding upper surface (34). Each of the support members (28) is releasably coupled to a corresponding one of the frames (22) by a fastening system (78). The plurality of frames (22) are configured to releasably couple to the panel (24), and the upper surfaces (34) of the frames (22) are each shaped to correspond with a portion of the profile of the tool-side surface (32) of the panel (24). A securing system (38) is configured to provide a suction force that releasably secures the panel (24) against the upper surface (34) of the frames (22). The base (20) includes a pair of bars (72) and a plurality of bars (74) mounted along the pair of bars (72), wherein the frames (22) slide on bars (72).
