Solution Overview

Problem

Existing cap opening and closing apparatuses for micro tubes struggle with diverse cap shapes and require high load to operate, limiting their ability to handle micro tubes from various manufacturers and efficiently perform high-throughput testing.

Innovation Solution

A cap opening and closing apparatus featuring a first rotary member with engaging portions that uncap micro tubes and a second rotary member with capping units that cap micro tubes by pushing their upper surfaces, allowing for diverse cap shapes and reduced operational load.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a single opening and closing unit with an angular U shape is used to open or close multiple micro tubes simultaneously, then productivity is improved, but the load required for operation increases significantly

Engineering Contradiction:
Improvenumber of micro tubes opened or closed simultaneouslyVSAvoidload for driving the opening and closing unit
Core Design Contradiction:
ProductivityVSForce

Solution Approach 1:

The opening and closing mechanism is divided into multiple independent opening and closing units, each capable of handling one or more micro tubes. Instead of using a single large unit that would require high load, the system segments the task across multiple smaller units, reducing the force required for each individual unit while maintaining the ability to process multiple micro tubes simultaneously.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If the opening and closing unit is structured with an angular U shape to engage caps, then ease of operation is improved, but adaptability to diverse cap shapes deteriorates

Engineering Contradiction:
Improveengagement mechanism simplicityVSAvoidcompatibility with different cap shapes and sizes
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The opening and closing units are designed with universal engagement structures that can accommodate various cap shapes and sizes. The units incorporate adjustable or flexible engagement surfaces that adapt to different cap geometries, allowing the same unit structure to effectively open and close caps from different manufacturers without requiring specialized designs for each cap type.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The opening and closing units incorporate dynamic elements such as flexible arms or adjustable positioning mechanisms that can adapt their shape and position to match different cap geometries. This dynamic adaptability allows the units to maintain effective engagement across diverse cap types while preserving the simplicity of the engagement mechanism.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If micro tubes from a specific manufacturer are used to ensure uniformity, then ease of operation is improved, but adaptability deteriorates due to supply chain constraints

Engineering Contradiction:
Improveconsistency in handling uniform micro tubesVSAvoidability to handle micro tubes from various manufacturers
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The cap opening and closing apparatus is designed with universal engagement structures that can accommodate caps from different manufacturers. The units incorporate adjustable parameters such as engagement force, positioning, and surface geometry that can be adapted to handle various cap types, ensuring the system can process micro tubes from multiple suppliers without compromising operational ease.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A cap opening and closing apparatus that opens and closes caps of a plurality of micro tubes, includes: a first rotary member that rotates around a first rotation axis; a plurality of first engaging portions which are mounted on the first rotary member, and which respectively uncap the plurality of micro tubes by temporarily engaging with the caps during rotation of the first rotary member; a second rotary member that rotates around a second rotation axis different from the first rotation axis; and a plurality of capping units that, during rotation of the second rotary member, respectively cap the plurality of micro tubes by converting a force of the rotation into a force that temporarily pushes upper surfaces of the caps.
