Envelope Flap Retraction Mechanism for Jam-Free Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing enclosing apparatuses face challenges in smoothly inserting enclosures into envelopes due to envelope flaps interfering with the insertion process, leading to inefficiencies and potential damage to the enclosure.
Innovation Solution
The enclosing apparatus incorporates an enclosing support mechanism that retracts the envelope flap from the conveyance path as the envelope is conveyed to the enclosing position, allowing for smooth insertion of the enclosure by widening the envelope opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the envelope is conveyed with the flap in the conventional position, then the envelope structure is simple, but the flap interferes with the enclosure insertion process
Solution Approach 1:
The patent applies the dynamics principle by making the envelope flap movable rather than fixed. The flap is configured to be retractable from the envelope conveyance path, allowing it to move between an extended position (when not in use) and a retracted position (during enclosure insertion). This dynamic adjustment eliminates interference with the insertion process while maintaining the simple envelope structure when the flap is not needed.
2Reliability
If the flap is retracted from the conveyance path, then the enclosure insertion is smooth and damage-free, but the device complexity increases
Solution Approach 1:
The patent applies the preliminary action principle by retracting the flap from the conveyance path before the enclosure reaches the insertion position. The enclosing support mechanism proactively prepares the conveyance path by moving the flap aside in advance, ensuring that when the enclosure arrives, the path is clear and ready for smooth, damage-free insertion. This prevents potential conflicts rather than reacting to them.
3Ease of manufacture
If the envelope is conveyed without retracting the flap, then the device structure is simple, but the enclosure may be damaged during insertion
Solution Approach 1:
The patent applies the taking out principle by extracting the flap from the active conveyance path during the enclosure insertion process. The enclosing support mechanism temporarily removes the flap from the path where the enclosure will travel, isolating it from the insertion process. This prevents the flap from causing damage to the enclosure while keeping the overall device structure relatively simple.

AI summary
An enclosing apparatus for enclosing an enclosure into an envelope at an enclosing position includes a conveyance roller that conveys the envelope to the enclosing position and an envelope conveyance path through which the envelope is conveyed. An enclosing support is disposed in the envelope conveyance path and supports enclosing of the enclosure into the envelope. The enclosing support retracts a flap of the envelope from the envelope conveyance path while the conveyance roller conveys the envelope to the enclosing position.
