Flower Bouquet Packaging with Drawstring 3D Forming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flower bouquet packaging requires multiple time-consuming operations and separate parts, leading to increased storage and assembly costs, as well as environmental concerns due to the need for multiple components.
Innovation Solution
A packaging system featuring a waterproof sheet with a reinforcing element having angular arms with loops and tightening links that can transform from a flat to a volume position by pulling on drawstrings, reducing the number of operations and facilitating easier storage and recycling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a rigid shaper is used to give final shape to the packaging, then the packaging shape is maintained, but storage space is increased and device complexity is increased
Solution Approach 1:
The patent removes the rigid shaper from the packaging system entirely, extracting only the essential shaping function. The flexible reinforcement with pre-formed arms and loops provides the necessary structural support and shape definition without requiring a separate rigid shaper component, thereby reducing storage space and device complexity while maintaining packaging shape.
Solution Approach 2:
The flexible reinforcement element is designed with pre-formed arms and loops that automatically define the packaging shape when the drawstring is pulled. The structure self-organizes into the final form through the tightening action, eliminating the need for an external rigid shaper to impose the shape, thus reducing both storage requirements and device complexity.
2Ease of manufacture
If multiple separate parts are used to form the packaging, then the packaging can be formed, but the number of operations increases and time is lost
Solution Approach 1:
The patent combines the reinforcement structure, shaping elements, and tightening mechanism into a single integrated flexible reinforcement element. The arms, loops, and drawstring attachment points are all part of one component that works together to form the packaging in a single operation, eliminating the need for multiple separate parts and reducing assembly time.
Solution Approach 2:
The flexible reinforcement element is pre-formed during manufacturing with arms and loops in their final positions. This preliminary configuration allows the packaging to be formed quickly during use by simply pulling the drawstring, without requiring multiple assembly steps or operations to construct the shaping structure.
3Ease of manufacture
If multiple separate parts are required to produce the packaging, then the packaging can be assembled, but storage space is increased and cost increases
Solution Approach 1:
The patent merges the reinforcement, shaping, and tightening functions into a single flexible reinforcement element with integrated arms, loops, and drawstring attachment points. This consolidation reduces the number of parts from multiple separate components to one unified element, thereby reducing device complexity, storage space requirements, and assembly costs while maintaining ease of manufacture.
4Shape
If a rigid shaper is used to form the packaging, then the final shape is achieved, but the device is difficult to store due to size and rigidity
Solution Approach 1:
The patent replaces the rigid, static shaper with a flexible reinforcement element that can dynamically change its configuration. The flexible arms can be stored in a compact, folded state and automatically extend into the final shaping configuration when the drawstring is pulled, providing both ease of storage and effective shape formation.
Solution Approach 2:
The patent uses a flexible reinforcement element with thin, adaptable arms instead of a rigid shaper. This flexible structure can be compressed into a small storage space and will naturally assume the required shaping form when activated by the drawstring tension, solving both the storage and shaping requirements.

AI summary
The packaging (1) has a packaging foil (10) which is impermeable to water. Two drawstrings pass successively through loops in several arms (21). The drawstrings pass respectively through two orifices of a pair of diametrically opposed arms, so as to diametrically oppose two grasping areas (30,40). Main packaging goes from a flat position to three-dimensional (3D) position by pulling the drawstrings and exerting forces in opposite directions on the grasping areas, in which a base (20) and the arms of reinforcing element are in same plane. An independent claim is included for a suspension assembly.
