Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional packaging systems for liquid, semi-liquid, cream, or paste products are complex to disassemble and reassemble, making the exchange of refillable parts time-consuming and costly, with multiple components contributing to higher production expenses and environmental impact.
Innovation Solution
The development of a packaging system that integrates a recyclable or biodegradable refill with a reusable cap, where the refill features minimal connection means and the cap has complex connection means, allowing for easy assembly and disassembly while reducing material usage and environmental impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional packaging systems use multiple components (container body, lid, exchangeable part), then the packaging provides complete functionality, but the complexity of disassembly and reassembly increases, making refill exchange time-consuming
Solution Approach 1:
The patent combines the container body and lid into a single integrated component, eliminating the need for separate assembly and disassembly operations. The integrated design allows the refill to be exchanged as a single unit, significantly simplifying the refill exchange process while maintaining all necessary functionalities.
Solution Approach 2:
The patent segments the packaging system into two main parts: a reusable integrated container (body and lid combined) and an exchangeable refill. This segmentation allows the complex container structure to remain intact while only the simpler refill needs to be replaced, reducing the operational complexity of refill exchange.
2Ease of manufacture
If conventional packaging systems include multiple parts (container body, lid, exchangeable part), then the packaging is functional, but the production cost increases due to multiple components
Solution Approach 1:
By merging the container body and lid into a single integrated component, the patent reduces the total number of parts that need to be manufactured, assembled, and quality-checked. This integration directly lowers production costs while maintaining the structural integrity and functionality of the container.
Solution Approach 2:
The patent applies the disposable principle to the refill component, which is designed to be inexpensive and replaceable. By making the refill a simple, disposable element rather than a complex reusable component, the overall manufacturing cost of the packaging system is reduced.
3Object-affected harmful factors
If conventional packaging systems have multiple components, then the packaging is functional, but the environmental impact increases due to more materials
Solution Approach 1:
The integration of container body and lid into a single component reduces the total quantity of materials required for packaging. Fewer separate parts mean less material production, processing, and transportation, directly reducing the environmental impact of the packaging system.
Solution Approach 2:
The patent enables easier recovery and recycling by simplifying the packaging structure. The integrated container can be more easily cleaned, disassembled for material recovery, and recycled. The disposable refill can be separately processed, improving overall material recovery efficiency and reducing environmental impact.
