Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid packaging devices with a rigid and flexible material combination are complex to produce, require two hands for operation, and lack tamper-proof security, as they rely on a cap that must be supplemented with additional elements for assurance.
Innovation Solution
A device with a substantially ovoid chamber comprising a rigid dispenser and a flexible material part, connected via a linking element made of similar rigid material, allowing for easy fluid expulsion and secure closure using a frangible connection and a foot-like closing element, enabling single-handed operation and stable positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the chamber is made entirely of flexible material as in prior art, then the device can be produced with simpler materials, but the device requires two hands for operation and lacks tamper-proof security
Solution Approach 1:
The chamber is divided into two distinct parts: a rigid first part containing the dispenser and a frangible connection for tamper-proof security, and a flexible second part for fluid storage and compression. This segmentation allows each part to perform its specific function optimally while enabling single-handed operation.
Solution Approach 2:
The frangible connection is pre-designed to break upon initial use, providing automatic tamper-proof security without requiring additional user actions. The rigid first part is pre-assembled with the dispenser, allowing the user to immediately use the device with one hand after breaking the seal.
2Ease of operation
If a cap is used to close the dispenser as in prior art, then the dispenser can be closed, but tamper-proof security is not ensured without additional elements
Solution Approach 1:
The frangible connection is pre-designed and assembled between the rigid first part and flexible second part, providing automatic tamper-proof security upon initial use. This preliminary preparation ensures that the device can be opened only once, guaranteeing that the fluid has not been accessed before purchase.
Solution Approach 2:
The frangible connection acts as an intermediary element between the rigid first part and flexible second part, providing a secure yet breakable bond that ensures tamper-proof security while allowing legitimate access to the fluid after initial opening.
3Device complexity
If the chamber is made entirely of flexible material as in prior art, then the structure can be simpler, but the production complexity increases due to requiring two independent elements
Solution Approach 1:
The device is segmented into two functional parts with distinct material properties: a rigid first part for structural support and dispenser housing, and a flexible second part for fluid containment and compression. This segmentation simplifies the overall structure while enabling efficient manufacturing of each component.
Solution Approach 2:
The device combines rigid and flexible materials in a composite structure, where the rigid first part provides structural integrity and the flexible second part provides fluid containment and compressibility. This composite approach simplifies the overall device design while facilitating manufacturing of each material-specific component.
