Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conveyor systems face challenges in maintaining smooth operation and alignment with the alignment of conveying platforms and ensuring that the carrier does not disturb the contents.
Innovation Solution
The proposed construction is based on a turning device with conveying platforms that rotate and transport carriers, featuring a side guide and coplanar platforms with adjustable heights, ensuring smooth transitions and alignment to prevent tipping or spilling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If belt-type conveyors are used for turning carriers, then the carriers can be turned, but the belts require regular maintenance and additional tightening mechanisms that increase device complexity and manufacturing cost
Solution Approach 1:
The patent removes the belt-type conveyor components and their associated tightening mechanisms from the turning device. Instead, it uses a simplified platform-based system where carriers are turned by rotating the platform itself, eliminating the need for separate belt tensioning and maintenance systems.
Solution Approach 2:
The turning device is divided into discrete, maintainable components including the platform, guide surfaces, and support structures. This segmentation allows each component to be independently maintained or replaced without affecting the entire system, reducing overall maintenance complexity.
2Adaptability or versatility
If carriers are turned by belt-type conveyors, then the direction can be changed, but the sharp turn causes disturbance to the contents, especially harmful for samples with separate liquid layers
Solution Approach 1:
The patent employs curved guide surfaces that form a smooth arc path for the carrier during turning. This curved geometry eliminates sharp corners and angles in the turning path, allowing the carrier to rotate smoothly without sudden changes in direction that would disturb the contents, particularly liquid layers.
Solution Approach 2:
The platform rotates dynamically to turn the carrier, while the guide surfaces are designed to accommodate this rotation with smooth transitions. The system adapts the turning motion to be continuous and controlled, preventing abrupt movements that would cause disturbance to the samples.
3Device complexity
If a gap and/or step is left between the conveyors and turning device, then the structure can be simpler, but the misalignment causes the carrier to hit the side of the turning device, causing tipping over or disruption
Solution Approach 1:
The patent introduces guide surfaces as intermediary elements between the incoming carrier path and the turning platform. These guide surfaces act as a mediator that smoothly transitions the carrier onto the rotating platform, eliminating gaps and misalignments that would cause the carrier to strike the side of the turning device.
Solution Approach 2:
The guide surfaces are positioned to preliminarily guide and align the carrier before it reaches the turning platform. This preliminary alignment action ensures the carrier is properly positioned and oriented before the turning motion begins, preventing tipping and disruption during the transition.
4Ease of operation
If the operational speed is lowered to overcome misalignment issues, then the carrier can travel more smoothly, but the overall operation efficiency of the system suffers
Solution Approach 1:
The curved guide surfaces create a smooth, continuous turning path that allows the carrier to change direction gradually without sharp angles. This curved geometry enables the system to maintain higher operational speeds while still ensuring smooth travel and preventing carrier disturbance, as the curvature distributes the turning motion over a longer, more controlled path.
