Solution Overview

Problem

Existing sink countertops for aircraft galleys and lavatories are costly, difficult to customize, and lack flexibility in design due to traditional molding methods, resulting in uniform and non-tailored shapes that do not meet airline-specific needs.

Innovation Solution

A method involving multiple layers of machined sheet material, where alignment features are used to stack and bond the layers with adhesive, followed by machining to form a finished assembly, allowing for customization and flexibility in design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional molding methods are used to manufacture sink countertops, then production efficiency and consistency are improved, but customization flexibility and design variety deteriorate

Engineering Contradiction:
Improveproduction efficiencyVSAvoidcustomization flexibility
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The countertop is divided into multiple layers (first layer, second layer, third layer, etc.) that can be manufactured separately and then stacked together. This segmentation allows each layer to be customized independently while maintaining efficient manufacturing processes for each individual layer, resolving the contradiction between production efficiency and customization flexibility.

Inventive Principle:
Principle #1Segmentation

2Manufacturing precision

If traditional molding methods are used to manufacture sink countertops, then manufacturing consistency is improved, but design customization and airline-specific tailoring deteriorate

Engineering Contradiction:
Improvemanufacturing consistencyVSAvoiddesign customization
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

By segmenting the countertop into multiple stackable layers, each layer can be manufactured with consistent precision using standardized processes, while the overall design can be customized by selecting and configuring different layers. This maintains manufacturing consistency while enabling design customization.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple standardized layers are merged through stacking and adhesive bonding to create customized countertop designs. Each individual layer maintains manufacturing consistency, while their combination allows for airline-specific tailoring and design customization.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of manufacture

If molding methods are used, then production cost is reduced through standardization, but flexibility in options and customization deteriorates

Engineering Contradiction:
Improveproduction costVSAvoidflexibility in options
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The countertop system is segmented into multiple interchangeable layers that can be manufactured using cost-effective standardized processes. These standardized layers maintain low production costs while their modular nature provides flexibility in options and customization by allowing different layer combinations.

Inventive Principle:
Principle #1Segmentation

4Adaptability or versatility

If multiple layers are stacked and bonded, then customization flexibility is improved, but manufacturing complexity increases

Engineering Contradiction:
Improvecustomization flexibilityVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Alignment openings and alignment members are incorporated into each layer during the preliminary manufacturing stage. This preliminary action ensures that when layers are stacked, they automatically align correctly, reducing the complexity of the assembly process despite having multiple customized layers.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Alignment members and alignment openings act as intermediaries that facilitate the stacking process. These features guide the positioning of each layer relative to others, simplifying the assembly of multiple customized layers and reducing manufacturing complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)
