Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If bone fragments are collected and processed using conventional systems, then bone graft can be obtained, but bone fragment recovery is not maximized and processing efficiency is insufficient
Solution Approach 1:
The device is divided into distinct functional modules: a collection chamber for receiving bone fragments, a press mechanism for compression, and a filtration system for liquid removal. This segmentation allows each component to be optimized for its specific function while maintaining overall sterile processing efficiency
Solution Approach 2:
The press mechanism is designed to be manually operated by the surgeon during the procedure, allowing real-time compression of bone fragments directly in the collection chamber without requiring separate processing steps. The filtration system automatically separates liquid components as they pass through, providing self-service liquid removal during the entire process
2Manufacturing precision
If bone fragments are compressed to remove liquid components, then homogenous bone graft product is achieved, but processing time and operational complexity increase
Solution Approach 1:
The collection chamber and press mechanism are integrated into a single unit that the surgeon can operate continuously during the procedure. The filtration system is merged with the compression mechanism, allowing liquid removal to occur simultaneously with compression rather than as a separate step, thereby maintaining operational simplicity while achieving homogenous bone graft
Solution Approach 2:
The device is pre-prepared with sterile components and pre-assembled filtration systems before the surgical procedure begins. The collection chamber is ready to receive bone fragments immediately, and the press mechanism is pre-positioned for immediate compression, eliminating setup time during the procedure while maintaining sterile conditions
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device ensures consistent and efficient processing of bone fragments into a homogenous bone graft by effectively separating liquid components, maintaining sterility, and ensuring high-quality bone graft production.
Implementation Method 1
a vacuum source configured to remove liquid components from the composition through the filter
Implementation Method 2
application of rotational force to the chamber and/or press member in a first direction moves the compression surfaces together to compress the composition between the compression surfaces to compact the composition and further remove liquid components

AI summary
A device (10) for collecting and processing bone fragments is disclosed. The device comprises a chamber member (12), a press member (14), an intake port (16), and a vacuum port (18). A compression surface (20) and a filter support surface (22) configured to support a filter are defined by said chamber and/or press member. The intake port is on the chamber and/or press member and is configured to receive a composition comprising bone fragments. The vacuum port is on the chamber and/or press member. The chamber member and the press member are rotationally coupled with one another. The composition is acquired through the intake port and collected between the compression surface and the filter support surface. The application of rotational force to the chamber and/or press member in a first direction moves the compression surface and the filter support surface together to compress the composition therebetween to compact, and further remove filtrate from the composition.
