Solution Overview

Problem

Existing methods for applying materials like foam or adhesives in the transportation industry require excessive equipment and often inconvenient timing during automotive vehicle assembly, leading to inefficiencies.

Innovation Solution

A system comprising two compartments with a mixing initiator that intermixes polymeric material and a curing agent to form an activatable material, which expands, foams, and cures to function as a baffle, seal, or reinforcement within a vehicle structure, eliminating the need for additional equipment and allowing for flexible application timing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional methods are used for applying materials like foam or adhesives, then material application can be achieved, but excessive equipment is required and application timing is inconvenient

Engineering Contradiction:
Improveapplication convenienceVSAvoidequipment quantity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system divides the material application process into two separate compartments: one containing polymeric material and the other containing curing agent. This segmentation allows each component to be stored and transported independently, eliminating the need for complex mixing equipment while enabling simple on-site mixing by combining the two compartments.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The polymeric material and curing agent are prepared and stored in separate compartments in advance, ready for application. This preliminary preparation eliminates the need for complex equipment during application, as the materials are already portioned and ready to be combined directly at the application site.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If traditional foam application methods are used, then foam can be applied to the structure, but the process requires additional equipment and has limited timing flexibility

Engineering Contradiction:
Improveapplication timing flexibilityVSAvoidequipment requirements
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system is self-sufficient, requiring no external equipment or infrastructure. The two compartments contain all necessary components (polymeric material and curing agent), and the mixing process occurs within the system itself through simple combination, eliminating dependence on external foam generation equipment and enabling application at any convenient time.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system can be used for multiple purposes including foam application, sealing, and reinforcement by simply changing the composition of the polymeric material and curing agent in the compartments. This multi-functionality eliminates the need for different equipment for different applications, providing timing and application flexibility across various uses.

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