Movable Floor Tray for High Density Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tray systems for storing and transporting goods, such as plastic containers, face challenges in achieving high pack density and efficient loading and unloading processes, often requiring complex devices and risking scratches from goods movement.
Innovation Solution
A tray design featuring a movable floor that can be raised for easy loading and unloading, eliminating the need for additional space within the tray for gripping units and allowing for direct access to the goods, thereby enhancing pack density and reducing the risk of scratches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If goods are packed loosely to facilitate loading and unloading, then accessibility is improved, but packing density decreases and goods can move around causing scratches
Solution Approach 1:
The patent applies the dynamics principle by making the base movable rather than fixed. The base can be raised to provide accessibility for loading and unloading operations, then lowered to maximize packing density and secure goods during transport. This dynamic adjustment resolves the contradiction between ease of operation and packing density.
2Productivity
If a gripping unit is used to load and unload goods, then loading efficiency is improved, but additional space within the tray is required which reduces packing density
Solution Approach 1:
The movable base allows the tray to accommodate a gripping unit externally without sacrificing internal packing density. The base can be raised to enable gripping operations from the outside, eliminating the need for internal clearance space while maintaining high packing density when the base is lowered.
Solution Approach 2:
The invention resolves the space conflict by moving the gripping operation to another dimension - external to the tray rather than internal. The movable base enables the gripping unit to operate from above or the side, eliminating the need for horizontal clearance within the tray cavity.
3Quantity of substance
If goods are placed directly into the tray without additional space, then packing density is maximized, but goods may drop with impact during loading
Solution Approach 1:
The movable base can be raised to create clearance space above the goods during loading operations, allowing them to be placed gently without impact. After loading, the base is lowered to maximize packing density and secure the goods for transport.
4Ease of manufacture
If trays are designed with fixed bases for structural simplicity, then manufacturing complexity is reduced, but loading and unloading require complex external devices
Solution Approach 1:
The movable base enables the tray to perform its own loading and unloading operations by providing accessibility when raised, eliminating or simplifying the need for complex external loading devices. The tray essentially loads and unloads itself through the movement of its base.
