Fold-Flat Conical Collection Device for Urine Sample Shipping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard urine collection cups are bulky and difficult to ship before and after sample collection, posing challenges in shipping and handling due to their three-dimensional structure.
Innovation Solution
A conical envelope-like collection device with flexible joints and support members that can be laid flat for shipping and easily transformed into an upright position for use, allowing for easy transfer of collected samples into smaller transport containers without additional equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a standard rigid plastic cup is used for urine collection, then the collection function is reliable, but the device becomes bulky and difficult to ship
Solution Approach 1:
The collection device is divided into multiple rigid members (first, second, and third members) that can be separated and folded flat for shipping, then assembled into a conical cup shape for use. This segmentation allows the device to occupy minimal space during transport while maintaining full functionality during collection.
Solution Approach 2:
The device transitions from a static flat-packed state to a dynamic three-dimensional conical structure through flexible joints and rotatable members. The ability to transform between compact and expanded states resolves the contradiction between shipping volume and collection reliability.
2Stability of the object's composition
If a rigid three-dimensional container is used, then the sample can be held securely, but shipping and handling complexity increases
Solution Approach 1:
By segmenting the container into foldable rigid members connected by flexible joints, the device achieves both stability when assembled and simplicity during shipping. Each member maintains structural integrity while the overall configuration simplifies to a flat package for transport.
Solution Approach 2:
The use of flexible joints and rotatable connections between rigid members allows the structure to adapt between compact and stable configurations, reducing shipping complexity while maintaining sample holding stability during use.
3Quantity of substance
If a bulky collection device is used, then the collection capacity is sufficient, but environmental impact increases due to shipping requirements
Solution Approach 1:
The segmented foldable design allows the collection device to be compact during shipping and expansion to adequate capacity during use, minimizing transportation emissions and environmental impact while maintaining sufficient collection volume.
Solution Approach 2:
The device transitions from a two-dimensional flat-packed state to a three-dimensional conical structure, enabling adequate collection capacity to be achieved only when needed, thereby reducing the environmental footprint associated with transporting bulky containers.

AI summary
A diagnostic testing aid for collecting body fluids for medical and health care industries. The collection device may comprise a conical envelope having a first end configured to be a closed end and a second end configured to be an open end. The conical envelope forms a cavity configured to hold liquid, such as urine from a urine stream. As a collection procedural step, the collection device may be set on a table upright with the use of a rigid member flexibly coupled to the conical envelope along a first joint which may be away from the conical envelope to provide support the conical envelope in the upright position. Then, when a shipping container is prepared, the collection device aids in pouring a sample into the shipping container using a crease and a tip in the conical envelope.
