Solution Overview
Problem
Existing packaging systems struggle to form consistent creases in corrugated cardboard boxes of varying dimensions, requiring manual replacement of creasing members and reducing productivity.
Innovation Solution
A packaging apparatus that measures the height of the stored object and forms horizontal creases on a cylindrical packaging box using rollers to ensure consistent crease formation, adaptable to different object heights without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If long convex and concave members are used to form creases across the entire horizontal area, then complete crease coverage is achieved, but pressure distribution becomes uneven causing inconsistent crease depth
Solution Approach 1:
The crease formation process is segmented into multiple passes. Instead of attempting to crease the entire horizontal area in one operation with long members, the apparatus creates creases sequentially across different sections, ensuring uniform pressure application in each segment while achieving complete coverage through multiple operations.
Solution Approach 2:
The apparatus introduces dynamic movement to the creasing process. The cylindrical body rotates during crease formation, allowing fixed or short creasing members to act on different horizontal sections sequentially. This dynamic approach maintains consistent pressure application while achieving complete crease coverage across the entire horizontal area.
2Manufacturing precision
If box dimension changes are accommodated by replacing convex and concave members, then crease formation accuracy is maintained, but device complexity and productivity are reduced due to replacement time
Solution Approach 1:
The apparatus employs universal creasing members that can accommodate multiple box dimensions without replacement. By using a cylindrical body with rotatable positioning and adjustable crease depth control, the same creasing members can effectively create accurate creases across various box sizes, eliminating the need for frequent component replacement.
Solution Approach 2:
The system uses dynamic adjustment mechanisms rather than static fixed members. The cylindrical body's rotation and the adjustable positioning of creasing members allow the system to adapt to different box dimensions dynamically during operation, maintaining crease formation accuracy without requiring physical replacement of components.
3Manufacturing precision
If box dimension changes are accommodated by replacing convex and concave members, then crease formation accuracy is maintained, but device complexity increases due to replacement mechanisms
Solution Approach 1:
The apparatus is designed with universal, adjustable creasing members that can accommodate multiple box dimensions without replacement. The cylindrical body with rotatable positioning and adjustable crease depth control allows the same components to effectively create accurate creases across various box sizes, eliminating the need for complex replacement mechanisms.
Solution Approach 2:
The system employs dynamic adjustment mechanisms rather than complex replacement systems. The cylindrical body's rotation and the adjustable positioning of creasing members provide flexibility to adapt to different box dimensions during operation, maintaining crease formation accuracy while keeping the device structure relatively simple.

AI summary
A packaging apparatus (2) packages a stored object (90) in a packaging box (1) having a cylindrical body (1W) and changes a height of the packaging box (1) dependent on a height of the stored object (90). The packaging apparatus (2) includes a height measuring part (30) which measures a height of the stored object (90) stored in the cylindrical body (1W), and a scoring part (31) which forms a horizontal crease (L3) in a wall (10) of the cylindrical body (1W) based on a result of the height measuring part (30) to divide the wall (10) into a side wall (15) and an upper flap (16). The scoring part (31) includes a roller part (43) which holds the wall (10) of the cylindrical body (1W) and moves in a horizontal direction while rolling on both front and rear surfaces of the wall (10) to form the horizontal crease (L3).
