Biodegradable Capsule Package With Moisture Barrier and Child Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laundry and dish wash water-soluble capsules face challenges with biodegradable packaging that is prone to premature degradation, leading to compromised integrity and increased child access, and pulp-based containers suffer from high water transmission, causing product sticking and performance issues.
Innovation Solution
A biodegradable packaging system using a substrate treatment product with a biodegradable material, printed on the inner surface of a water-soluble film, and a child-resistant closure mechanism to ensure product integrity and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If biodegradable packaging material is used, then environmental friendliness is improved, but packaging integrity and resistance to premature degradation worsen
Solution Approach 1:
The packaging uses a composite structure combining biodegradable material with a water-soluble film barrier layer. The biodegradable material provides environmental benefits while the water-soluble film coating on the inner surface prevents moisture transmission and premature degradation, maintaining packaging integrity throughout storage and transport.
2Duration of action of stationary object
If pulp-based container is used, then biodegradability is improved, but water transmission rate increases causing product sticking
Solution Approach 1:
The packaging applies a water-soluble film coating specifically on the inner surface where product contact occurs. This creates a local barrier property that prevents water transmission and product sticking in the critical contact zone, while the bulk pulp material maintains its biodegradable characteristics for environmental disposal.
3Object-affected harmful factors
If child-resistant closure is added, then safety is improved, but device complexity increases
Solution Approach 1:
The closure mechanism uses an intermediary locking system where a removable cap with a safety latch provides child-resistant protection. The latch requires simultaneous application of force to multiple points or a specific motion sequence, creating a barrier against child access while maintaining relative simplicity through the use of a separate, attachable closure component rather than integrating complexity into the main packaging structure.
