Envelope Processing Apparatus with Adjustable Enclosure Pushing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing envelope processing systems lack efficient mechanisms for inserting and sealing enclosures into envelopes, particularly in ensuring precise alignment and adjustment of the enclosure within the envelope, which affects the visibility of information and the overall sealing process.
Innovation Solution
An envelope processing apparatus equipped with an envelope conveyor, flap opener, enclosure pusher, and circuitry that adjusts the pushing amount of the enclosure into the envelope based on the envelope's opening, allowing for precise insertion and sealing, including modes for protrusion and non-protrusion of the enclosure from the envelope body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the enclosure is pushed into the envelope with a fixed pushing amount, then the structure is simple, but the alignment precision and information visibility are poor
Solution Approach 1:
The patent applies dynamics by making the pushing amount adjustable rather than fixed. The enclosure pusher can change its pushing distance dynamically based on the envelope opening size, allowing the system to adapt to different conditions and achieve precise alignment without a overly complex fixed mechanism.
Solution Approach 2:
The patent changes the parameter of pushing amount from a fixed value to an adjustable variable. By allowing the pushing amount to be modified according to the envelope opening, the system achieves better alignment precision while maintaining reasonable structural complexity.
2Ease of operation
If the enclosure is always pushed completely inside the envelope, then the sealing is complete, but the information visibility is reduced
Solution Approach 1:
The system dynamically adjusts the pushing amount based on user needs and envelope conditions. Rather than always pushing the enclosure completely inside, the adjustable mechanism allows the enclosure to remain partially visible when needed, improving user convenience while maintaining information accessibility.
Solution Approach 2:
Instead of always performing the full action of pushing the enclosure completely inside the envelope, the system allows for partial pushing when appropriate. This partial action maintains information visibility while still providing adequate enclosure, balancing sealing completeness with information accessibility.
3Productivity
If the envelope opening is large, then the enclosure insertion is easy, but the alignment precision decreases
Solution Approach 1:
The system uses feedback from the envelope opening size to adjust the pushing amount. When the envelope opening is large, the system compensates by adjusting the pusher's force or distance to maintain proper alignment, ensuring that insertion efficiency does not compromise alignment precision.
Solution Approach 2:
The pushing amount parameter is changed based on the envelope opening size. When the opening is large, the system adjusts the pushing parameters to achieve the correct alignment, allowing efficient insertion while maintaining precision through dynamic parameter modification.

AI summary
An envelope processing apparatus that inserts an enclosure into an envelope includes an envelope conveyor, a flap opener, an enclosure pusher, and circuitry. The envelope conveyor extends in a vertical direction and conveys the envelope to an enclosing position via an envelope conveyance passage as a passage in which the envelope is conveyed. The flap opener opens a flap of the envelope. The enclosure pusher pushes the enclosure toward an opening of a body of the envelope conveyed to the enclosing position with the flap open. The circuitry changes a pushing amount of the enclosure into the envelope and adjusts the pushing amount based on the opening of the body of the envelope within a specified range from an inside to an outside of the body of the envelope.
