Solution Overview

Problem

Conventional methods for creating surface replicas of components, such as turbine blades, often result in replicas with insufficient thickness and uniformity, leading to potential cracking and loss of quality due to the free-form application of solidifying compounds, especially around edges.

Innovation Solution

A mold assembly with adjustable brackets and a sealing mechanism that allows for precise formation of a mold cavity around the component surface, ensuring a consistent and uniform thickness of the replica by selectively coupling to the component surface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the liquid solidifying compound is applied in a free form manner, then the application process is simple, but the resulting replica has insufficient thickness and uniformity

Engineering Contradiction:
Improveapplication process simplicityVSAvoidreplica thickness uniformity
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

A mold assembly with brackets and seals is introduced as an intermediary device between the compound application process and the component surface. The mold cavity defined by the brackets and seals ensures uniform compound distribution and consistent replica thickness, resolving the contradiction between simple application and precise thickness control.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The mold assembly allows adjustment of the distance between brackets, enabling control over the mold cavity dimensions. This parameter adjustment ensures that the solidifying compound maintains a consistent thickness throughout the replica, achieving uniformity while maintaining ease of application.

Inventive Principle:
Principle #35Parameter changes

2Area of stationary object

If the liquid solidifying compound is applied across edges of components, then complete surface coverage is achieved, but the replica may crack and be unusable

Engineering Contradiction:
Improvesurface coverage areaVSAvoidreplica integrity
Core Design Contradiction:
Area of stationary objectVSReliability

Solution Approach 1:

The mold assembly with adjustable brackets and sealing elements acts as a mediator that enables complete edge coverage while preventing compound pooling. The seals ensure the compound remains within the mold cavity boundaries, and the adjustable brackets accommodate various component geometries, maintaining replica integrity across the entire surface area.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Manufacturing precision

If the mold assembly is made adjustable to ensure uniform thickness, then replica quality is improved, but the device complexity increases

Engineering Contradiction:
Improvereplica thickness consistencyVSAvoidmold assembly structure
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The mold assembly is divided into separate adjustable brackets that can be independently positioned and secured. This segmentation allows for simple adjustment mechanisms on each bracket rather than a complex integrated system, achieving uniform thickness control while keeping individual components relatively simple.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mold assembly incorporates adjustable and reconfigurable elements that can be modified to match different component geometries. This dynamic capability allows the same basic mold structure to adapt to various surfaces, maintaining precision without requiring entirely different complex molds for each application.

Inventive Principle:
Principle #15Dynamics
