Paper Bag With Segmented Adhesive Closure And Tear-Off Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional paper containers, such as sacks and envelopes, are not adaptable in size and are not reusable, leading to inefficiencies in packaging and shipping, particularly in e-commerce, where items often do not fit properly and return packaging is wasteful, and existing shipping containers are often too large, wasting space and resources.
Innovation Solution
A paper container with a handle, a folded and glued bottom, and two adhesive elements that can be activated separately, allowing the opening to be closed and reopened for reuse, along with a tear-off element for access, enabling size adjustment and recyclability, and potentially incorporating a ventilation path to prevent bursting under additional load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional paper containers are used, then they are simple and inexpensive to manufacture, but they cannot be adjusted in size and are not reusable
Solution Approach 1:
The container is divided into a body and a separate closure element (envelope back) that can be detached and reattached. This segmentation enables the container to be opened, closed, and reused multiple times while maintaining structural integrity and size adaptability through different closure configurations.
Solution Approach 2:
The container incorporates dynamic closure mechanisms with adhesive elements that can be activated or deactivated. The closure element can be positioned in different states (open, partially closed, fully closed) allowing the container to adapt its sealing degree based on storage and transport requirements, enhancing both adaptability and reusability.
2Volume of stationary object
If conventional shipping boxes are used, then they are available in standard sizes, but they are often too large for the products, wasting space
Solution Approach 1:
The closure element can be positioned at different locations around the container opening, allowing the effective volume of the container to be adjusted. This dynamic positioning enables optimal space utilization for products of varying sizes while maintaining the same container body, eliminating the need for multiple box sizes.
Solution Approach 2:
The container's effective storage volume parameter can be changed by repositioning the closure element. This allows the same physical container to serve multiple volume requirements, adapting to different product sizes and reducing wasted shipping space without requiring a family of different-sized containers.
3Ease of operation
If tear-off strips are used for opening containers, then access is easy, but the container cannot be reused
Solution Approach 1:
The closure system is segmented into a tear-off portion for easy initial opening and a reusable adhesive portion for subsequent closures. The tear-off element provides straightforward access while the remaining adhesive closure mechanism enables multiple reuse cycles, combining the benefits of easy opening with reusability.
Solution Approach 2:
The tear-off element is extracted as a separate, disposable component from the main closure system. This extracted element performs the single function of initial opening easily, while the remaining container structure with adhesive elements retains full reusability for multiple closure and opening cycles.
4Reliability
If adhesive elements are used for closing containers, then sealing is secure, but they cannot be activated separately for selective closure
Solution Approach 1:
The adhesive closure system is segmented into multiple independently activatable adhesive elements positioned at different locations on the closure element. This segmentation allows selective activation of individual adhesive elements based on storage needs, while each element maintains secure sealing capability when activated.
Solution Approach 2:
The adhesive elements are designed to be dynamically activatable through simple actions such as peeling off protective covers or applying pressure. This dynamic activation capability allows the closure security to be adjusted on-demand without complex mechanisms, maintaining reliability while enabling flexible, selective closure of different container sections.
