Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional paper boxes require unnecessary material stock and adhering procedures for partitioning, leading to increased production costs.
Innovation Solution
A layered structure for a paper box comprising an inner box, an outer cover, and a carrying plate, where the inner box has a stepped surface to support the carrying plate, and the outer cover sleeves over the inner box, reducing material usage and adhering costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If two layers of paper boards are adhered to form partitions, then the paper box structure is stable and functional, but material stock increases and production cost rises
Solution Approach 1:
The paper box is divided into separate functional components: an inner box for structure, an outer cover for protection, and a carrying plate for partitioning. These segments are designed to work together without requiring adhesive bonding between layers, eliminating material waste while maintaining structural integrity through their cooperative arrangement.
Solution Approach 2:
The carrying plate is nested within the inner box, and the inner box is nested within the outer cover. This nested configuration allows the components to support each other structurally without requiring additional adhesive materials, reducing material stock while maintaining stability.
2Stability of the object's composition
If two layers of paper boards are adhered to form partitions, then the paper box structure is stable and functional, but the adhering procedure increases production complexity and cost
Solution Approach 1:
By segmenting the paper box into separate components (inner box, outer cover, carrying plate) that do not require adhesive bonding, the manufacturing process is simplified. Each component can be produced independently and assembled without complex adhering procedures, reducing production complexity and cost while maintaining structural stability.
Solution Approach 2:
The structural support function and the partitioning function are merged into a single integrated carrying plate design. The carrying plate itself provides both the partitioning structure and the support mechanism through its flange engagement with the inner box, eliminating the need for separate adhering processes and simplifying manufacturing.
3Ease of operation
If a stepped surface is formed by adhering two paper boards, then the carrying plate can be supported, but material stock and production cost increase
Solution Approach 1:
The stepped surface is formed locally on the inner box at the specific location where the carrying plate needs support. This localized feature is integrated into the inner box design rather than requiring a separate adhered paper board layer, providing the necessary support function while avoiding material waste associated with full-layer adhering.
Solution Approach 2:
The support function for the carrying plate is merged into the inner box structure itself. The stepped surface is an integral part of the inner box that provides support, eliminating the need for separate adhered layers and reducing material stock requirements while maintaining the ease of operation for carrying plate placement.

AI summary
A layered structure for a paper box includes an inner box, an outer cover and a carrying plate. The inner box is formed with a first opening, and a stepped surface is formed at the inner edge of the first opening. The outer periphery of the carrying plate is formed with a flange, and the carrying plate is disposed in the first opening and the flange thereof is supported by the stepped surface. The outer cover is formed with a second opening, the second opening is sleeved with the first opening, and the outer cover is served to cover the first opening and cover outer sides of the inner box. Because the stepped surface is integrally formed in the inner box, the manufacture procedure of the layered structure for a paper box can be simplified thereby reducing material stock and lowering production cost.
