Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tableware taking devices face issues with increased weight, unreliable discharge due to large swing blocks, and cumbersome manual handling, leading to inefficient tableware removal and potential sticking within the magazine.
Innovation Solution
A linkage-type misalignment material discharge structure featuring a support block with a rotation shaft and drive element, allowing for perpendicular misalignment of discharge portions and using pull rods and positioning pins for controlled material discharge, eliminating the need for a swing block and reducing weight and complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a swing block is used to pull tableware from the magazine, then the tableware can be discharged, but the device weight increases and becomes difficult to move
Solution Approach 1:
The support block is divided into multiple support sheets (first support sheet, second support sheet, third support sheet) stacked on a rotation shaft. Each support sheet has discharge portions misaligned in the perpendicular direction, allowing the system to be segmented into lighter, functional units that rotate to discharge tableware without requiring a heavy swing block
Solution Approach 2:
Instead of using a swing block to pull tableware horizontally, the invention inverts the approach by using a rotating support block to discharge tableware vertically through misaligned discharge portions. The tableware falls naturally due to gravity when the discharge portions are misaligned, eliminating the need for a heavy pulling mechanism
2Ease of operation
If a large swing block is used, then tableware can be pulled out, but the discharge reliability decreases as tableware may not be completely displaced from the support block
Solution Approach 1:
The discharge portions on different support sheets are misaligned in the perpendicular direction (vertical dimension) rather than being arranged in the same horizontal plane. This dimensional misalignment ensures that when one support sheet rotates to discharge tableware, the tableware is completely displaced from the support block without interference from other support sheets, improving discharge reliability
Solution Approach 2:
The support block is designed to rotate dynamically around the rotation shaft, with each support sheet being able to rotate into position to discharge tableware. This dynamic rotation allows precise control of the discharge process, ensuring tableware is completely displaced from the support block before falling, thereby improving reliability
3Reliability
If tableware gets stuck in the magazine, then manual handling is required to take out and stack tableware, but this process is numerous and cumbersome, greatly affecting dining time
Solution Approach 1:
The rotating support block with multiple misaligned discharge portions enables continuous discharge operation. When one support sheet is discharging tableware, other support sheets are positioned to receive or discharge tableware, ensuring the discharge process continues without interruption or manual intervention, thereby preventing tableware from getting stuck and reducing dining time
Solution Approach 2:
The misaligned discharge portions are pre-positioned on different support sheets before operation begins. This preliminary arrangement ensures that as each support sheet rotates into position, the discharge portions are already correctly oriented to guide tableware discharge, preventing sticking situations before they occur and eliminating the need for manual handling
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enables accurate, reliable, and efficient tableware discharge without translation movement, reducing friction and weight, improving reliability, and simplifying the discharge process, while minimizing contact and handling risks.
Implementation Method 1
one end of the rotation shaft is connected with a swing rod provided with a clamping groove, the drive element is provided with a position limitation column matched with the clamping groove; wherein the support block is rotated for discharging the material under a drive of the drive element
Implementation Method 2
When the support block has rotated for a misalignment angle, the material in the lower layer would lost its support platform, and then the fall for discharging without any forward, backward, leftward or rightward movement
