Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in efficiently cutting and sealing pouches for oral products, particularly those designed for adult consumers, without causing irritation or discomfort.
Innovation Solution
A cutting assembly comprising a first and second housing with blade holders and heaters, allowing for precise cutting and sealing of pouches, utilizing a pneumatic cylinder for blade movement and angled extensions for alignment and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a blade is used to cut the pouch, then cutting efficiency is improved, but sharp edges are generated causing oral irritation
Solution Approach 1:
The patent applies local quality by providing different surface characteristics at different locations of the cutting assembly. The blade surface is treated to be substantially smooth to minimize oral irritation, while the cutting edge maintains sharpness for efficient cutting. This resolves the contradiction by having the blade possess both cutting efficiency and oral comfort properties through localized surface treatment.
Solution Approach 2:
The patent converts the potentially harmful sharp edges of the blade into a beneficial smooth surface that is safe for oral contact. By treating the blade surface to create a smooth finish, the harmful sharp edges are transformed into a feature that prevents oral irritation, thus converting harm into benefit while maintaining cutting efficiency.
2Device complexity
If the blade holder is fixed in position, then structural simplicity is improved, but adaptability to different pouch sizes is reduced
Solution Approach 1:
The patent applies dynamics by making the blade holder movable rather than fixed. The blade holder can be positioned at different locations along the cutting assembly to accommodate different pouch sizes and configurations. This dynamic positioning capability provides adaptability to various pouch types while maintaining relatively simple structural implementation through linear movement mechanisms.

AI summary
An apparatus for cutting and sealing a pouch includes a first housing, a blade holder, and a second housing. The first housing includes a first base wall, a first sidewall, and a second sidewall. The first sidewall and the second sidewall extend from respective ends of the first base and define a first gap. The blade holder is configured to be inserted into the first gap of the first housing and hold a blade. The blade holder is configured to move between a retracted position and an extended position. The second housing includes a second base wall, a third sidewall, and a fourth sidewall extending from respective ends of the second base wall and defining a second gap. The first sidewall is parallel to the second sidewall and the first sidewall and the second sidewall are perpendicular to the first base wall.
