Equipment Transfer Locking Mechanism for Misalignment-Tolerant Docking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical equipment transfer systems are inefficient and hazardous due to the lack of a secure locking mechanism, complex and costly components, and inadequate alignment sensitivity, leading to accidental dislodging and increased staff training requirements during patient transport.
Innovation Solution
A transfer device with a clamshell housing and security mechanism that securely locks equipment between stationary and mobile platforms using a vertical lift mechanism, minimizing misalignment issues and reducing component complexity and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a security mechanism is added to prevent accidental dislodging, then reliability improves, but device complexity increases
Solution Approach 1:
The security mechanism automatically engages and disengages based on the relative positions of the transfer device and support platform, without requiring manual operation. The system self-regulates the locking state through the interaction of the first and second security levers with the docking cones, eliminating the need for external control inputs.
Solution Approach 2:
The security mechanism transitions between locked and unlocked states dynamically based on the docking condition. When both docking cones are engaged, the system automatically locks; when either cone disengages, the system automatically unlocks, creating a dynamic response to operational conditions.
2Ease of manufacture
If standardized components are used, then manufacturing cost decreases, but adaptability to different platforms worsens
Solution Approach 1:
The transfer device is designed with universal docking interfaces that can accommodate both stationary and mobile support platforms. The first and second docking cones are configured to work with standardized docking cups on various platform types, allowing the same device to serve multiple functions across different healthcare settings.
3Ease of operation
If alignment sensitivity is reduced, then ease of operation improves, but manufacturing precision requirements worsen
Solution Approach 1:
The docking interfaces utilize conical geometry for the docking cones and corresponding receptacles. This curved, tapered design provides self-aligning characteristics that guide the components into proper engagement, reducing sensitivity to initial misalignment while maintaining secure connection.
