Packaging Storage Container Tray Hinge Shock Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional packaging storage containers for sheet-like objects often have issues with the tray's hinged shaft breaking easily and the tray being unstable, leading to sheet-like objects falling off during handling and storage.
Innovation Solution
A packaging storage container design featuring a tray connected to articulated shaft-receiving bases with self-adaptive rotation and shock absorption, along with protuberance members and press-hold mechanisms to secure the objects, preventing the tray from breaking and objects from falling off.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the tray is hinged to the 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 packaging container is divided into separate components: a container body, a removable tray, and an articulated shaft-receiving base. The tray is segmented from the container body and connected through a receiving base that houses the articulated shaft, allowing independent replacement and reducing stress concentration on the shaft itself.
Solution Approach 2:
The articulated shaft is nested within the articulated shaft-receiving base, which is integrated into the container body. This nested structure protects the shaft while allowing the tray to pivot, combining protection with operational functionality.
2Ease of operation
If the tray is hinged to allow turnover, then the container is accessible, but the tray moves back and forth irregularly and blocks cover overturning
Solution Approach 1:
The tray connection system transitions from a fixed rigid hinge to a dynamic receiving base structure that allows controlled movement during tray insertion and removal, then stabilizes the tray in its operational position. The base absorbs irregular movements while maintaining stable tray positioning during use.
Solution Approach 2:
The articulated shaft-receiving base acts as an intermediary between the tray and the container body. It mediates the connection by providing a stable mounting point that allows tray turnover while preventing excessive back-and-forth movement that would block cover operation.
3Stability of the object's composition
If the tray is secured to prevent movement, then stability is improved, but the tray cannot be turned over for access
Solution Approach 1:
The connection system provides dynamic stability - the tray is firmly secured during normal use to prevent unwanted movement, yet the articulated shaft-receiving base allows controlled turnover motion when needed for access. The system adapts its degree of restraint based on operational requirements.
