Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a spout is provided on the top surface of the pouch, then contents can be dispensed from the top, but the pouch becomes difficult to grip and requires tilting during dispensing
Solution Approach 1:
The patent applies local quality by creating a recessed portion specifically at the grip location (side seal portion) while maintaining the overall pouch structure. This localized modification provides enhanced gripability without altering the entire pouch design, allowing users to easily hold and tilt the pouch during dispensing from the top spout.
2Ease of operation
If the pouch is designed for easy gripping, then dispensing becomes convenient, but the pouch structure becomes more complex
Solution Approach 1:
The patent segments the side seal portion into distinct functional zones: an upper grip portion with the recessed portion for easy holding, and a lower seal portion for sealing the pouch. This segmentation allows each part to perform its specific function optimally - the recessed portion aids gripping while the seal portion maintains sealing integrity, thus improving dispensing convenience without unnecessarily complicating the overall structure.

AI summary
At least one of a left side seal portion or a right side seal portion includes recessed portions recessed toward the inside of packaging bag so that an outer edge of the packaging bag is constricted in a width direction in a state in which the packaging bag-10 is folded so that a top gusset sheet overlaps each of a folded portion where a part of the front surface sheet closer to a top gusset sheet is folded and a back surface sheet while the front surface sheet is located on the back surface sheet in a state of including the folded portion.
