Packaging Storage Container With Shock-Absorbing Articulated Shaft
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional packaging storage containers for sheet-like objects face issues with the articulated shaft breaking easily and the tray being unstable, leading to irregular movement and potential ejection during container closure and falls.
Innovation Solution
A packaging storage container design featuring a container bottom and cover hinged to a ridge member with articulated shaft-receiving bases providing self-adaptive rotation and shock absorption, along with guiding members to ensure smooth tray movement and prevent breakage, and protuberance members for secure object holding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a tray is hinged to a packaging container body with an articulated shaft, then the tray can be turned over for access, but the articulated shaft is easily broken and the tray becomes unstable
Solution Approach 1:
The patent applies beforehand cushioning by providing shock-absorbing elements and protective structures around the articulated shaft before failure occurs. The container body includes recesses and cushioning materials positioned to absorb shocks and prevent direct impact on the articulated shaft during normal use and abnormal situations like drops.
Solution Approach 2:
The patent segments the tray support system by separating the articulated shaft from direct contact with the container walls through recesses and protective structures. This segmentation isolates the vulnerable articulated shaft component, allowing it to move independently within a protected space while maintaining tray accessibility.
2Ease of operation
If the tray is hinged to allow overturning, then the tray can be accessed, but the tray moves back and forth with irregular trajectory blocking cover overturning
Solution Approach 1:
The patent employs asymmetry in the design of the recesses and guiding structures within the container body. The recesses are positioned and shaped asymmetrically to guide the tray along a specific predetermined trajectory during overturning, preventing irregular back-and-forth movement while maintaining easy access.
Solution Approach 2:
The patent introduces intermediary structures such as recesses and guiding walls within the container body that mediate between the tray and the container walls. These intermediary elements guide the tray's movement along a controlled path, ensuring smooth overturning without irregular trajectories.
3Ease of operation
If the tray is allowed to move freely for access, then the tray can be turned over easily, but the tray is unstable when closed and may shake inside the container
Solution Approach 1:
The patent applies dynamics by designing the recesses and protective structures to adaptively respond to the tray's position. When the tray is open, the structures allow free movement for access; when the tray is closed, the same structures engage to limit movement and provide stability, creating a dynamic system that changes its constraints based on operational state.
4Reliability
If the container is designed for protection, then the articulated shaft is protected from breakage, but the structure becomes more complex
Solution Approach 1:
The patent merges multiple functions into the container body structure itself. The recesses serve dual purposes: they protect the articulated shaft from external impacts while also guiding the tray's movement trajectory. This merging of protection and guidance functions into a single structural element avoids increasing overall device complexity.
