Packaging Material Shock Absorption Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional packaging materials, especially those formed from corrugated cardboard, tend to deform and lose their shock-absorbing functionality when subjected to external forces, and they are prone to deterioration during assembly and disassembly, which reduces their reusability.
Innovation Solution
A packaging material design featuring a base portion and shock-absorbing portions with specific vertical plate and hook-like configurations that maintain structural integrity and prevent deformation, allowing the material to effectively absorb shocks without collapsing, while also facilitating easy assembly and disassembly without folding outside pre-defined lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional packaging materials are subjected to external forces, then they deform and lose shock-absorbing functionality, but maintaining structural integrity under load requires a more robust design
Solution Approach 1:
The packaging material is divided into multiple vertical plate portions (first through fourth) that can independently deform and absorb shock. Each plate portion acts as a separate shock-absorbing element, allowing the structure to maintain integrity while distributing impact forces across multiple segments rather than a single monolithic structure.
Solution Approach 2:
The packaging material incorporates bending portions that allow dynamic deformation under external forces. The vertical plate portions can flex and bend at the connecting bending portions, enabling the structure to adapt to impact forces dynamically rather than remaining rigid, thus maintaining shock-absorbing functionality while withstanding loads.
2Ease of operation
If packaging material is assembled and disassembled repeatedly, then it deteriorates and loses reusability, but easy assembly and disassembly requires simpler connection methods
Solution Approach 1:
The packaging material includes pre-formed hook-like portions and corresponding insertion portions that are prepared in advance during manufacturing. These pre-formed connection elements enable straightforward assembly by simply engaging the hooks with insertion portions without requiring complex fastening operations, while the robust design of these connection elements ensures they withstand repeated assembly and disassembly cycles.
3Stability of the object's composition
If the packaging material structure is made more complex to maintain integrity, then assembly becomes more difficult, but simple structures are prone to deformation
Solution Approach 1:
The packaging material features an asymmetric arrangement of vertical plate portions and bending portions that provides structural stability without requiring excessive complexity. The asymmetric design allows optimal placement of shock-absorbing elements at strategic locations, maintaining integrity where needed while keeping the overall structure relatively simple and assembly-friendly.

AI summary
A packaging material is formed from a shock-absorbing plate material and stored in a packaging box with a packaged article. The packaging material includes a base portion and a shock absorbing portion. The shock absorbing portion surrounds three sides of a space along a main surface of the base portion. First and second vertical plate portions of the shock absorbing portion face each other and continue to the base portion. In the shock absorbing portion, a third vertical plate portion continues to the second vertical plate portion, and a fourth vertical plate portion continues to the third vertical plate portion. The fourth vertical plate portion is overlaped on the first vertical plate portion. A hook portion of the shock absorbing portion continues to the fourth vertical plate portion, and has a second cut in which a bottom portion of the first cut of the first vertical plate portion is inserted.
