Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current gripper devices require separate devices for gripping and opening sample cases, leading to increased space and cost due to the need for multiple devices with different functionalities.
Innovation Solution
A gripper assembly with a base, rotatable grippers, and a power transmission system that allows for simultaneous gripping and opening of sample cases using a single device, featuring a controller to manage the grippers' rotational speed and elastic members for adjustable holding force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate gripper devices are used for gripping and opening sample cases, then each device can be optimized for its specific function, but the total space occupied increases and cost increases
Solution Approach 1:
The patent combines a gripping device and an opening device into a single integrated gripper assembly. The gripping portion holds the sample case while the opening portion simultaneously opens the lid, eliminating the need for separate devices and reducing space occupation.
Solution Approach 2:
The gripper assembly is designed with multi-functionality, serving both as a gripping device and an opening device. The same assembly can adapt to different operations (gripping and opening) through its dual-structure design, making it a universal tool for sample case handling.

3Area of stationary object
If a single gripper assembly is used for both gripping and opening, then space and cost are reduced, but control over holding force becomes more complex
Solution Approach 1:
The patent employs elastic bodies (springs) that provide dynamic, adjustable holding forces. The elastic bodies automatically adjust the gripping force based on the sample case characteristics, simplifying control while maintaining adaptability. The elastic restoration force provides natural force regulation without complex control systems.
4Area of stationary object
If a single gripper assembly is used for both gripping and opening, then space and cost are reduced, but the structural design becomes more complex
Solution Approach 1:
The gripper assembly is segmented into distinct functional portions: a gripping portion with grippers for holding the sample case, and an opening portion with opening members for opening the lid. This segmentation allows each portion to be optimized independently while maintaining overall simplicity.
Solution Approach 2:
The patent employs elastic bodies (springs) that provide dynamic, adjustable holding forces. The elastic bodies automatically adjust the gripping force based on the sample case characteristics, simplifying control while maintaining adaptability. The elastic restoration force provides natural force regulation without complex control systems.
