Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rigid containers for fluent products are expensive to produce, require significant materials, are difficult to decorate, prone to damage, and challenging to resize without incurring high costs and time-consuming mold changes, making it hard for manufacturers to adjust product sizes efficiently.
Innovation Solution
Flexible containers made from materials that can be easily converted into various sizes without the need for new equipment, offering reduced material usage, easier decoration, and improved durability, allowing for efficient resizing and cost-effective production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional rigid containers are used, then structural integrity is maintained, but production cost increases and material usage increases
Solution Approach 1:
The patent employs flexible container bodies made from thin-film materials that can be sealed and formed into functional containers. This approach eliminates the need for rigid, material-intensive construction while maintaining sufficient structural integrity for containing and dispensing products. The flexible shell structure uses significantly less material compared to conventional rigid containers, directly addressing the contradiction between strength and material usage.
Solution Approach 2:
The patent utilizes composite material structures combining flexible outer layers with internal support elements or coatings. This composite approach provides the necessary structural integrity and strength while keeping material usage minimal. The multi-layer composite construction allows the container to maintain its shape and resist deformation without requiring thick walls or excessive material, thus resolving the contradiction between strength and material efficiency.
2Strength
If conventional rigid containers are used, then structural integrity is maintained, but ease of decoration deteriorates
Solution Approach 1:
The flexible container structure provides a smooth, continuous surface that is inherently more suitable for decoration compared to rigid containers with seams, ribs, or complex geometries. The flexible film can be printed on directly or have labels applied more easily, improving the ease of decoration while maintaining structural integrity through the sealed construction and support elements.
3Adaptability or versatility
If conventional rigid containers are used, then product size is fixed, but adaptability to resize deteriorates
Solution Approach 1:
The patent employs dynamic, adjustable support structures that can be reconfigured to accommodate different container sizes and shapes. Rather than being fixed to a single mold, the support elements can be adjusted or repositioned, allowing the same manufacturing equipment to produce various container configurations. This dynamic capability enables easy resizing and adaptation without requiring time-consuming mold changes, directly resolving the contradiction between adaptability and time loss.
Solution Approach 2:
The manufacturing equipment and support structures described in the patent are designed with universal applicability, capable of handling multiple container types and sizes through reconfiguration rather than requiring dedicated molds for each product size. This multi-functional design allows a single production line to adapt to different product requirements, eliminating the need for costly and time-consuming mold changes while maintaining structural integrity across various container configurations.
4Adaptability or versatility
If flexible materials are used, then ease of resizing is improved, but structural integrity may deteriorate
Solution Approach 1:
The patent employs composite material structures that combine flexible outer layers with internal support elements, rigid coatings, or reinforcing features. This composite construction provides the necessary structural integrity and strength while maintaining the flexibility and ease of resizing. The multi-layer composite approach allows the container to be reconfigured or adjusted without compromising its ability to maintain structural integrity during use.
Solution Approach 2:
The patent applies local quality enhancements by providing targeted reinforcement at specific locations where structural integrity is most needed, such as at seams, corners, or high-stress areas. The flexible material maintains its ease of resizing in areas where flexibility is needed, while localized rigid elements or reinforced construction provide the necessary strength. This differentiated approach resolves the contradiction between ease of resizing and structural integrity by applying different properties where appropriate.
