Reinforced Cellulose Container Frame for Load Stability and Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containers, such as cardboard and plastic trays, lack sufficient structural rigidity, stability, and resistance to loads, are prone to collapse, and have issues with sealing and tamper-proof lids, leading to inefficiencies in packaging, transport, and storage.
Innovation Solution
A container with an independent reinforcement frame composed of a single continuous piece that integrates a tray and a reinforcement frame, featuring folding tabs and a cover made from the same material, with locking mechanisms to ensure secure closure and enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If additional laminated layers, fillers, tongues, tabs, and means of adhesion are used to reinforce container walls or corners, then the resistance and stability are improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The reinforcement structure is divided into separate modular components: a reinforcement frame made of rigid material and folding tabs made from the container material itself. These segmented elements can be independently manufactured and assembled, reducing overall complexity while maintaining strength.
Solution Approach 2:
The invention combines different materials with complementary properties: a rigid reinforcement frame material provides structural strength, while the folding tab material (same as container) provides flexibility and adhesion. This composite approach achieves high resistance without excessive complexity.
2Strength
If thick plastic pieces are used to provide structural strength, then the resistance is improved, but the ease of folding and adhesion deteriorates
Solution Approach 1:
The structure is segmented into a rigid reinforcement frame that provides strength and flexible folding tabs made from thinner material that can be easily folded and adhered. This segmentation allows each component to be optimized for its specific function.
Solution Approach 2:
Different parts of the structure have different material thicknesses and properties: the reinforcement frame uses thicker, more rigid material where strength is needed, while the folding tabs use thinner, more flexible material where ease of manipulation is critical. This local differentiation resolves the contradiction.
3Strength
If excess material is left as surplus to form frame structures, then the resistance is improved, but the loss of substance increases
Solution Approach 1:
The invention changes the geometric parameters of the reinforcement structure by using folding tabs that can be collapsed flat during storage and assembly. This parameter change allows the same material to provide full frame reinforcement when needed while minimizing material usage during storage and transport.
Solution Approach 2:
The reinforcement frame incorporates dynamic elements like folding tabs that can change shape from a flat stored configuration to a three-dimensional reinforced structure during use. This dynamic transformation allows the structure to achieve full strength only when needed, reducing material waste.
4Ease of operation
If conventional trays without independent reinforcement frames are used, then the ease of operation is improved, but the stability and resistance to loads deteriorate
Solution Approach 1:
The invention merges the reinforcement frame with the container body through integrated folding tabs that connect the two components. This merging ensures that the reinforcement structure moves with the container, maintaining stability while preserving ease of operation as a single unit.
Solution Approach 2:
The folding tabs act as intermediary elements that connect the reinforcement frame to the container body. These intermediaries transfer and distribute loads between the simple container structure and the reinforcement frame, maintaining both ease of operation and structural stability.
