Synchronization Bulk for Rotating Shafts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connection devices for rotating shafts often experience sticking issues between the rotation shafts and guide wheels, leading to non-smooth rotation.
Innovation Solution
A connection device comprising a guide bulk, first and second rotation shafts, and a synchronization bulk that slides between the shafts, ensuring synchronous rotation by using grooves and a position limitation section within the guide bulk to prevent sticking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two rotation shafts are used to realize synchronous rotation, then the rotation synchronization is achieved, but the rotation shafts easily get stuck between the rotation shafts and the guide wheel resulting in non-smooth rotation
Solution Approach 1:
The patent introduces a synchronization bulk as an intermediary component between the first and second rotation shafts. This synchronization bulk includes a position limitation section that slides within a guide groove on the guide bulk, mediating the interaction between the two rotation shafts. The intermediary structure prevents direct harmful contact between the rotation shafts and guide wheel, eliminating the sticking problem while maintaining rotation synchronization.
2Ease of operation
If a guide wheel is used to guide the rotation shafts, then the rotation path is controlled, but the guide wheel causes sticking with the rotation shafts leading to non-smooth operation
Solution Approach 1:
The patent inverts the traditional guiding mechanism by replacing the guide wheel with a guide bulk that uses a guide groove instead of a wheel-contact interface. The position limitation section of the synchronization bulk slides within the guide groove, inverting the contact method from rolling (guide wheel) to sliding within a groove, which eliminates the sticking harmful factor while maintaining rotation path control.
3Reliability
If the synchronization bulk is added to prevent sticking, then rotation smoothness is improved, but the device complexity increases
Solution Approach 1:
The patent merges multiple functions into the synchronization bulk: it serves as both the synchronization mechanism (ensuring both shafts rotate together) and the anti-sticking mechanism (through the position limitation section sliding in the guide groove). By combining these functions into a single component rather than adding separate elements, the patent prevents sticking and maintains rotation smoothness while minimizing the increase in device complexity.

AI summary
A connection device for an apparatus includes a first rotation shaft, a second rotation shaft, a synchronization bulk, and a guide bulk. The first rotation shaft includes a first synchronization section set with a first groove; the second rotation shaft is in parallel with the first rotation shaft and includes a second synchronization section set with a second groove. The synchronization bulk includes a first end, a second end disposed opposite the first end, and a position limitation section, with the first end being disposed within the first groove and capable of sliding within the first groove, the second end being disposed within the second groove and capable of sliding within the second groove; the guide bulk being set with a first containing groove, a second containing groove, and a guide groove containing groove.
