Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bone cement mixing systems require significant manual effort for mixing components, and there is a need for systems that can be operated manually or with mechanical assistance, depending on user preference, while ensuring simplicity, safety, and flexibility.
Innovation Solution
An adapter for a mixing system that allows reversible connection to both a handle and an electric drive device, enabling the mixing rod to be operated mechanically, with a fastening element for the handle and a connecting element for the electric drive device, facilitating easy integration and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a manually operable mixing rod is used, then the bone cement paste can be prepared without additional aids and under sterile conditions, but a considerable amount of manual effort is required
Solution Approach 1:
The mixing system allows dynamic switching between manual operation mode and electrically assisted operation mode. The adapter enables the mixing rod to be operated either by hand or by connecting to an electric drive device, providing flexibility to adapt to different operational needs and reduce manual effort when required.
Solution Approach 2:
The adapter serves as an intermediary component between the electric drive device and the mixing rod. It provides a reversible connection interface that allows mechanical force transmission from the electric drive device to the mixing rod, enabling electrical assistance without compromising the sterile closed system.
2Device complexity
If the mixing system is designed for manual operation only, then the structure remains simple, but it lacks flexibility for users who prefer mechanical assistance
Solution Approach 1:
The mixing system is designed with multi-functionality through the adapter, which enables the system to operate in multiple modes: manual operation and electrically assisted operation. The adapter acts as a universal interface that can be connected or disconnected as needed, providing versatility without permanently increasing system complexity.
Solution Approach 2:
The system is segmented into modular components: the mixing system itself, the adapter, and the electric drive device. The adapter is a separate, reversible component that can be attached when electrical assistance is needed and removed when manual operation is preferred, allowing the system to maintain simplicity while gaining adaptability.
3Adaptability or versatility
If an adapter is added to enable electrical operation, then operational flexibility is improved, but device complexity increases
Solution Approach 1:
The adapter is designed as a separate, standalone component rather than integrating electrical components directly into the mixing system. This segmentation allows the adapter to be added only when needed, maintaining the simplicity of the core mixing system while providing optional electrical operation capability.
Solution Approach 2:
The adapter serves as a simple intermediary component that bridges the electric drive device and the mixing rod without adding complex control systems or mechanisms to the mixing system itself. It provides a straightforward mechanical connection interface that enables force transmission while keeping the overall system architecture simple.

AI summary
An adapter for a mixing system for preparing a bone cement paste from two starting components, comprising a fastening element for reversibly fastening the adapter to a handle of the mixing system, wherein the handle is designed to mix the two starting components in a container of the mixing system by means of a mixing rod of the mixing system and to thus prepare the bone cement paste, and a connecting element for reversibly connecting the adapter to an electric drive device, wherein the adapter is designed to establish a force-transmitting connection between the electric drive device and the handle so that the mixing rod can be mechanically operated using the electric drive device.
