Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of eccentric rotating devices in cleaning apparatuses is cumbersome due to the need for precise alignment of multiple linkage mechanisms, leading to difficulties in assembly.
Innovation Solution
The eccentric rotating device incorporates an actuator and follower mechanism that allows the first and second rotating assemblies to be rotated relative to each other, enabling the actuator to abut with the follower, thereby simplifying the assembly process by transmitting power between the assemblies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If traditional linkage mechanisms are used for power transmission between rotating assemblies, then power transmission is achieved, but assembly complexity increases and installation becomes cumbersome
Solution Approach 1:
The patent extracts the complex linkage mechanism from the power transmission system and replaces it with a direct actuator-follower contact mechanism. The actuator is disposed on the first rotating assembly while the follower is disposed on the second rotating assembly, eliminating the need for intermediate linkage components and simplifying the overall structure.
Solution Approach 2:
The patent introduces an actuator-follower pair as an intermediary mechanism between the two rotating assemblies. This actuator-follower interface serves as a simplified mediator that directly transmits power through contact, replacing the traditional complex linkage system and reducing assembly complexity.
2Measurement precision
If precise alignment of multiple linkage mechanisms is required, then power transmission accuracy is improved, but installation difficulty increases
Solution Approach 1:
The patent removes the requirement for precise alignment of multiple linkage mechanisms by extracting this complexity from the system. The actuator and follower are designed to engage through simple relative rotation, eliminating the need for complex alignment procedures while maintaining effective power transmission.
Solution Approach 2:
The patent incorporates preliminary action by pre-configuring the actuator and follower positions on their respective rotating assemblies. During assembly, the operator simply rotates the assemblies relative to each other by a predetermined angle to bring the actuator and follower into engagement, eliminating the need for complex alignment operations.
3Power
If actuator and follower are offset by predetermined distance during assembly, then power transmission is enabled, but assembly steps increase
Solution Approach 1:
The patent applies preliminary action by pre-calculating and pre-configuring the predetermined rotation angle required to bring the actuator and follower into engagement. This allows assembly operators to perform a single predetermined rotation operation rather than performing multiple trial-and-error alignment steps, reducing assembly time.
Solution Approach 2:
The patent merges the power transmission function with the assembly operation itself. By designing the actuator and follower such that their engagement occurs naturally through a predetermined rotation, the patent combines the power transmission setup with the assembly process, eliminating separate adjustment steps and reducing overall assembly time.
