Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional screen printing presses are heavy, cumbersome, and difficult to transport, requiring many tools and man-hours to disassemble, and none meet the size and weight requirements for standard airline luggage while maintaining functionality and high-quality print production.
Innovation Solution
A collapsible screen printing apparatus with retractable platens, a carbon fiber road case, and innovative structural components that allow for simultaneous operation by two operators, meeting FAA and TSA standards for luggage, enabling efficient and competitive operation with reduced weight and space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional screen printing presses are designed for high-quality print production, then printing capability is improved, but weight increases to 140 kilograms
Solution Approach 1:
The press is divided into six separate arms that can be independently folded and collapsed. Each arm contains its own squeegee mechanism and screen mounting capability, allowing the system to maintain full printing functionality while being segmented into transportable units that fold compactly into the road case.
Solution Approach 2:
The press transitions from a static, fixed structure to a dynamic, collapsible structure. The arms can be folded parallel to the road case walls, and the entire assembly can be collapsed into a compact configuration for transport, then deployed for operation. This dynamic transformation allows the press to adapt between operational and transport states.
2Reliability
If traditional presses are designed for stability and functionality, then operational reliability is improved, but device complexity increases requiring many tools and man-hours to disassemble
Solution Approach 1:
The press is divided into six separate arms that can be independently folded and collapsed. Each arm contains its own squeegee mechanism and screen mounting capability, allowing the system to maintain full printing functionality while being segmented into transportable units that fold compactly into the road case.
Solution Approach 2:
The road case serves multiple functions: it is the structural housing for the press, the transport container, and the storage unit for all components. The case walls serve as mounting surfaces for the folded arms, eliminating the need for separate storage containers or complex disassembly procedures.
3Productivity
If traditional presses occupy large space for operation, then functional capability is improved, but volume increases to 500 cubic feet
Solution Approach 1:
The press transitions from a static, fixed structure to a dynamic, collapsible structure. The arms can be folded parallel to the road case walls, and the entire assembly can be collapsed into a compact configuration for transport, then deployed for operation. This dynamic transformation allows the press to adapt between operational and transport states.
Solution Approach 2:
The six arms are arranged to fold parallel to the road case walls, nesting within the available space. The arms can be positioned in a compact configuration where they occupy minimal volume, fitting within the 3.9 cubic foot constraint when collapsed.
4Ease of operation
If the apparatus is designed to meet airline luggage standards, then transportability is improved, but structural strength must be maintained at 22 kilograms
Solution Approach 1:
The road case is constructed from composite materials that provide high strength-to-weight ratio, enabling the entire press assembly to meet airline luggage weight limits while maintaining sufficient structural integrity for printing operations. The carbon fiber reinforced polymers and aluminum alloys used in the construction provide the necessary strength without excessive weight.
