Dispensing Nozzle Tip Cutting for High-Capacity Disposal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing preprocessing devices face inefficiencies in accommodating dispensing nozzle tips, leading to accumulation issues when the disposal box reaches its capacity, causing temporary suspension of processing and potential blockages due to stacked nozzle tips.
Innovation Solution
A preprocessing device equipped with a cutting mechanism that cuts dispensing nozzle tips from the longitudinal side, improving accommodation efficiency and preventing accumulation by allowing for dispersed disposal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a camera module is disposed inside the display module, then the terminal device achieves a more compact structure and smaller size, but the camera module is prone to being damaged and difficult to repair
Solution Approach 1:
The device is divided into separate modules: the display module containing the camera module, and the front cover assembly. The camera module can be independently accessed by separating these modules, enabling repair while maintaining compact integration during normal operation.
Solution Approach 2:
A fastening component acts as an intermediary mechanism between the display module and front cover assembly, allowing controlled access to the camera module. This mediator enables both compact integration and easy disassembly for repair purposes.
2Device complexity
If the camera module is integrated inside the display module, then the overall device structure is simplified, but disassembly and repair of the camera module become inconvenient
Solution Approach 1:
The device structure is segmented into distinct assemblies (display module with camera module, and front cover assembly) that can be separated. This segmentation maintains simplified integrated structure during use while enabling easy access to the camera module for repair by separating the assemblies.
Solution Approach 2:
The fastening component provides a dynamic connection that can be easily engaged and disengaged. This dynamic fastening mechanism allows the structure to transition from a tightly integrated state during operation to a separated state for repair, and back again after repair.
3Volume of moving object
If the camera module is disposed inside the display module, then the terminal device achieves a more compact structure, but the camera module cannot be easily accessed for repair or replacement
Solution Approach 1:
The device is divided into separable modules where the camera module resides within the display module, which can be independently separated from the front cover assembly. This segmentation enables compact integration during normal operation while providing easy access to the camera module for repair by simply separating the modules.
Solution Approach 2:
The fastening component serves as an intermediary that connects the display module and front cover assembly during normal operation, enabling compact structure. When repair is needed, this intermediary can be easily released to provide access to the camera module, and re-engaged after repair to restore the compact structure.

Function Achieved in This Case
The cutting mechanism effectively enhances the disposal efficiency of dispensing nozzle tips, reducing accumulation and maintaining continuous processing by allowing for efficient disposal within the disposal box.
Implementation Method 1

AI summary
Provided is a preprocessing device that carries out a dispensing process for aspirating a liquid sample accommodated in a sample container, and subsequently discharging and dispensing the sample into another sample container, the preprocessing device comprising: a dispensing nozzle; a dispensing nozzle tip detachably provided to the distal end of the dispensing nozzle; a disposal box in which the dispensing nozzle tip is disposed of after having been removed from the dispensing nozzle; and a cutting mechanism for cutting a dispensing nozzle tip inserted into a removal part, which removes the dispensing nozzle tip from the dispensing nozzle, from the longitudinal-direction side. This makes it possible to improve accommodation efficiency while suppressing accumulation of disposed-of dispensing nozzle tips.
