Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing enclosing-sealing devices face issues with inconsistent content delivery timing, leading to incomplete enclosure or envelope breakage, which affects the quality of sealed matters.
Innovation Solution
An enclosing-sealing device with a delivery timing determiner and controller that adjusts delivery timing based on inputted information about the content and envelope, using correction tables to ensure proper synchronization during the folding process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the delivery timing is set constant in advance, then the device operation is simple, but the delivery timing becomes improper depending on content or envelope states
Solution Approach 1:
The patent applies dynamics by making the delivery timing adjustable rather than fixed. The delivery timing determination unit dynamically sets the delivery timing based on detected states of the content (thickness, number of sheets) and envelope (thickness, perforation presence), allowing the system to adapt to varying conditions while maintaining reliable operation.
2Manufacturing precision
If the delivery timing is too late, then the content can be fully prepared, but the enclosed state becomes incomplete causing enclosing failure
Solution Approach 1:
The patent implements feedback by using detection units to sense the actual states of content and envelope, then using this information to adjust the delivery timing. This closed-loop control ensures the content is delivered at the optimal moment - neither too early nor too late - preventing enclosing failure while maintaining complete content preparation.
3Productivity
If the delivery timing is too early, then the content delivery is timely, but the envelope breaks degrading folding quality
Solution Approach 1:
The patent applies parameter changes by adjusting the delivery timing parameter based on detected envelope and content states. The system calculates optimal delivery timing by considering envelope thickness, content thickness, and other parameters, delivering the content at precisely the right moment to prevent envelope breakage while maintaining timely delivery and high folding quality.

AI summary
An enclosing-sealing device for preparing a sealed matter by sealing an envelope with a content enclosed in the envelope includes a content formation unit, an envelope formation unit, a content delivery unit, a seal unit, a delivery timing determiner, and a delivery controller. The content delivery unit delivers the content delivered from the content formation unit to the envelope formation unit such that the content is enclosed in a sheet of envelope paper while being folded. The seal unit seals the envelope delivered from the envelope formation unit with the content enclosed in the envelope. The delivery timing determiner determines a delivery timing of the content by the content delivery unit based on inputted information about at least one of the content and the envelope. The delivery controller controls the content delivery unit to deliver the content to the envelope formation unit in accordance with the determined delivery timing.
