Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging inserts made of paper for fixing objects in boxes are not dimensionally stable on their own, requiring a large amount of space in packaging lines and cannot be produced separately, making them inefficient.
Innovation Solution
A device with a feeding unit and erecting unit using suction devices to form webs with acute angles, allowing for the production of compact, dimensionally stable packaging inserts that can be produced separately and stacked, featuring a second feed unit for additional stability and adhesive application for enhanced fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If packaging inserts are produced separately, then productivity is improved, but device complexity increases due to requiring large space in packaging lines
Solution Approach 1:
The packaging insert is designed to be nested within the box structure, with the insert's flaps extending to form walls that are positioned within the box's internal dimensions. This nesting allows the insert to be produced separately and stored compactly before being inserted into the box, resolving the contradiction between separate production capability and space requirements.
Solution Approach 2:
The packaging insert transitions from a two-dimensional flat layout to a three-dimensional structured form through predetermined fold edges and crease edges. This dimensional transformation allows the insert to be compact when flat (for separate production and storage) but expands to provide sufficient structural volume when erected within the box, eliminating the need for large device complexity during production.
2Reliability
If packaging inserts are made dimensionally stable, then reliability is improved, but ease of manufacture deteriorates due to requiring complex erecting mechanisms
Solution Approach 1:
The packaging insert is pre-cut and pre-folded with predetermined fold edges and crease edges before erection. This preliminary preparation of the flat layout ensures that when the insert is erected, it automatically forms the correct three-dimensional structure with stable dimensions, eliminating the need for complex erecting mechanisms while guaranteeing dimensional reliability.
Solution Approach 2:
The packaging insert is designed to be self-erecting through its predetermined fold edges and crease edges that guide the formation of walls and bases. The insert structure itself provides the guidance and mechanical advantage needed for erection, without requiring external complex machinery, thus maintaining ease of manufacture while achieving dimensional stability.
3Loss of time
If packaging inserts are produced separately, then loss of time is reduced, but area of stationary object increases due to space requirements in packaging lines
Solution Approach 1:
The packaging system is segmented into separate components: the box and the packaging insert are produced independently. The insert is manufactured as a separate entity with predetermined folds, allowing it to be produced, stored, and inserted without requiring continuous integration equipment, thus reducing production time while minimizing the area needed for stationary production equipment.
Solution Approach 2:
The packaging insert utilizes a two-dimensional flat design that transforms into three-dimensional structure during insertion. This dimensional approach allows the insert to be produced on standard flat cutting equipment (minimizing stationary area) while achieving the necessary structural volume when erected, eliminating the need for large dedicated production spaces.
