Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual mixing and injection operations are used, then the device structure remains simple, but the surgery time is prolonged and operator burden increases
Solution Approach 1:
The patent combines the mixing device and injection device into a single integrated apparatus. The mixing container serves as both the mixing chamber and the injection syringe body, with the plunger mechanism serving dual purposes for both mixing agitation and injection delivery. This merging eliminates the need for separate tools and reduces operational steps.
Solution Approach 2:
The plunger mechanism is designed to perform multiple functions: it agitates the bone cement during mixing by moving the mixing blade, and subsequently delivers the mixed cement during injection. The mixing container also serves dual purposes as both mixing chamber and injection syringe. This multi-functionality reduces the number of components needed.
2Ease of operation
If separate mixing and injection tools are used, then each function can be optimized independently, but the operation process becomes complex and time-consuming
Solution Approach 1:
The patent merges the mixing tool and injection tool into a single integrated device. The mixing container serves as both the mixing chamber and the injection syringe body, with the plunger mechanism serving dual purposes for both mixing agitation and injection delivery. This merging eliminates the need for separate tools and reduces operational steps.
3Measurement precision
If frequent movement between operating table and imaging room is required for volume control, then injection precision is maintained, but radiation exposure increases and surgery time is prolonged
Solution Approach 1:
The patent replaces the manual mechanical control system with an automated electronic control system. Motors drive both the plunger for injection and the mixing blade, with speeds and volumes controlled electronically. This substitution eliminates the need for frequent manual interventions and imaging room visits.
4Extent of automation
If automatic mixing and injection is implemented, then surgery time is reduced and operator burden is lightened, but the device complexity increases
