Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The reliability of the electrical connection between the control mechanism module and the infusion mechanism module in existing drug infusion devices is poor, affecting normal device operation.
Innovation Solution
The control mechanism module and infusion mechanism module are electrically connected by multiple first and second electrical contacts that are pressed against each other, with the first electrical contact protruding from the control mechanism module surface to ensure optimal contact, and the use of elastic conductive members like conductive springs enhances the reliability of the connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the control mechanism module and infusion mechanism module are assembled together, then the device can function, but the electrical connection reliability is poor
Solution Approach 1:
The first electrical contact is pre-configured to protrude from the control mechanism module surface before assembly. This preliminary positioning ensures that when the modules are assembled, the electrical contacts are already in optimal contact position, improving connection reliability without requiring complex alignment procedures during assembly.
Solution Approach 2:
The protruding first electrical contact acts as an intermediary element between the control mechanism module and infusion mechanism module. It facilitates reliable electrical connection by extending beyond the module surface to ensure firm contact with the second electrical contact, while the modular design keeps the overall system complexity manageable.
2Reliability
If the first electrical contact protrudes from the surface, then contact reliability improves, but manufacturing precision requirements increase
Solution Approach 1:
The first electrical contact is designed with localized protrusion only at the contact point, while the rest of the module maintains its compact structure. This local quality approach ensures reliable electrical contact where needed without requiring high precision across the entire module, reducing overall manufacturing precision requirements.
Solution Approach 2:
The protruding contact is pre-formed during the manufacturing of the control mechanism module housing, rather than requiring precise assembly of separate components. This preliminary formation of the contact geometry simplifies the manufacturing process and reduces the precision requirements for final assembly.

AI summary
A drug infusion device includes a control mechanism, provided with first electrical contacts exposed to a surface of the control mechanism; and an infusion mechanism, including a housing, and the infusion mechanism being provided with second electrical contacts exposed on a surface of the housing. When the control mechanism and the infusion mechanism are assembled with each other, the first electrical contacts and the second electrical contacts press against each other, thereby electrically connecting the control mechanism with the infusion mechanism. An end of the first electrical contact is flush with the control mechanism surface or protruding from the surface of the control mechanism in contact with the first electrical contact. When the control mechanism and the infusion mechanism are assembled, the first electrical contact and the second electrical contact may be contacted preferentially, the reliability of the electrical connection between the control mechanism and the infusion mechanism is improved.
