Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid supply devices require manual operation to detach sealing parts, which can increase worker workload and expose them to hazards, especially when handling hazardous liquids, and existing robotic solutions struggle with precise motion control during detachment.
Innovation Solution
A cap detachment device featuring a detachment mechanism with a holding part, a rotary part, and a pushing part that automates the detachment process by rotating and moving the cap part relative to the plug, using a flexible shaft and elastic member for precise motion control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a robot hand is used to hold and rotate the sealing part for automated detachment, then worker safety and workload are improved, but the complexity of the device increases and the operation becomes less reliable due to difficulty in coordinating robot hand motion with cap part movement
Solution Approach 1:
The detachment mechanism is designed to be self-sufficient by integrating the holding part, support part, and pushing part. The elastic member automatically provides pushing force to move the holding part along the second axis as the cap part detaches, eliminating the need for complex external control systems to coordinate motion.
Solution Approach 2:
The support part acts as an intermediary between the gripping mechanism and the holding part. It allows the holding part to move along the second axis while being supported by the grip part, enabling automated detachment without requiring the gripping mechanism itself to move.
2Ease of operation
If the robot hand position is fixed while rotating the sealing part, then the operation is simplified, but the detachment fails because the sealing part moves away from the plug during rotation
Solution Approach 1:
The system transitions from a static robot hand position to a dynamic configuration where the holding part moves along the second axis. The elastic member provides dynamic pushing force that automatically adjusts to the detachment progress, allowing the holding part to follow the cap part's movement while maintaining a fixed grip on the cap part.
Solution Approach 2:
The holding part combines multiple functions: it holds the cap part for rotation, moves along the second axis to follow cap part detachment, and is pushed by the elastic member to maintain contact. This merging of functions into a single component simplifies the overall system while ensuring reliable detachment.
3Extent of automation
If a pushing mechanism is added to automatically move the holding part during cap detachment, then the automation is improved and worker safety is enhanced, but the device complexity and space requirements increase
Solution Approach 1:
The elastic member is implemented as a compact, flexible component that can be integrated within the existing detachment mechanism structure. It provides the necessary pushing force while occupying minimal space, allowing automated motion control without significantly increasing the mechanism's volume.
Solution Approach 2:
The support part is attached to the grip part in a nested configuration, allowing the holding part to move along the second axis within the compact structure of the detachment mechanism. This nesting arrangement enables automated motion control while maintaining a compact overall design.
