Trading Card Mailer Structure for Machinable Sleeve Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional trading card mailers are excessively bulky, leading to non-machinable status and high mailing costs due to rigidity and lack of flexibility, which violates first class letter standards.
Innovation Solution
A specially configured trading card mailer with low weight and bulk components, incorporating a No. 10 paper envelope with U-shaped transitions and flexible tensioning cards or adhesive bonds to maintain alignment and machinability, using clear polyvinyl chloride sleeves to hold trading cards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional thick and durable exterior envelopes with bulky interior packing components are used, then trading card top loader sleeves are securely held and protected, but the mailer becomes excessively bulky and non-machinable, resulting in excessive mailing fees
Solution Approach 1:
The patent replaces conventional thick and rigid envelope structures with a thin, flexible polymer film envelope that can conform to the shape of the trading card and top loader sleeve. This flexible film provides adequate protection while minimizing bulk, enabling the mailer to meet first class letter size and weight requirements for machinable mailing.
Solution Approach 2:
The patent eliminates bulky interior packing components that were traditionally used to secure top loader sleeves within envelopes. Instead, the flexible polymer film envelope directly contains the top loader sleeve through its conforming shape and adhesive properties, removing unnecessary bulk while maintaining security.
2Reliability
If conventional rigid envelope structures are used, then trading card top loader sleeves are securely positioned, but the mailer lacks flexibility and is deemed non-machinable by post office standards
Solution Approach 1:
The patent employs a flexible polymer film envelope that can bend and flex during postal sorting operations while maintaining the positioning of the trading card. The film's flexibility allows it to adapt to handling and sorting processes, ensuring machinability while the adhesive properties prevent sleeve displacement.
Solution Approach 2:
The patent creates a dynamic system where the flexible polymer film envelope can adapt its shape during mailing and sorting processes. The film transitions from a flat state during insertion to a conforming state during handling, providing both flexibility for machinability and stability for secure positioning throughout the mailing process.
3Weight of moving object
If low weight and low bulk components are used to achieve machinability, then first class letter rate is qualified, but the mailer may lack sufficient structural support to maintain slide stopping and overlap preventing positions
Solution Approach 1:
The patent uses a composite structure combining a thin flexible polymer film with adhesive properties and integrated structural features such as flaps and sealing elements. This composite design provides sufficient structural support for maintaining sleeve positioning while keeping the overall weight and bulk low enough to qualify for first class letter rates.
Solution Approach 2:
The patent concentrates structural support features at specific locations where needed, such as adhesive zones for securing the top loader sleeve and flap structures for closure. The majority of the envelope body remains thin and flexible, providing overall structural integrity without excessive weight or bulk.
