Innovation Solution

A system and method utilizing an outer tool and an inner tool with a pneumatic arrangement to deliver adhesive to the edges of open cells in a conformal array, where the outer tool is made of a flexible material like Polytetrafluoroethylene or silicone, and the inner tool is made of metal, facilitating secure bonding and easy removal without separate sealing members.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If rigid tools are used for adhesive application, then structural stability is improved, but friction and damage to the conformal array increase

Engineering Contradiction:

Solution Approach 1:

The outer tool is constructed from flexible material (silicone or Polytetrafluoroethylene) that can deform to conform to the curved surfaces of the conformal array cells. This flexibility allows the tool to adapt to the aerodynamic profile without causing friction or damage, while still providing sufficient structural stability for precise adhesive application and tool removal.

Inventive Principle:
Principle #30Flexible shells and thin films

2Manufacturing precision

If adhesive is applied manually, then control precision is improved, but assembly time and productivity decrease

Engineering Contradiction:

Solution Approach 1:

The system combines automated adhesive delivery through the inner tool conduit with the flexible outer tool that provides precise positioning and sealing. This integration allows automated adhesive application with controlled precision while maintaining high assembly speed, eliminating the need for manual adhesive application.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The flexible outer tool acts as an intermediary between the adhesive delivery system and the conformal array cell. It receives adhesive from the inner tool and distributes it precisely along the cell edges through its flexible walls, ensuring accurate adhesive placement while maintaining high assembly throughput.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If the outer tool is made of flexible material, then ease of insertion and removal is improved, but tool strength decreases

Engineering Contradiction:
