Adjusting Mechanism and Grinder Using Same
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grinders lack fine adjustment capabilities, limiting the fineness of ground coffee bean powder, as they typically use stepped adjustment mechanisms that restrict precise control over the grinding base and wheel positioning.
Innovation Solution
An adjusting mechanism comprising a grinding base adjusting ring, a fixed ring, a rotating ring, and a guide ring connected through threads, allowing for stepless adjustment of the grinding base and wheel, enabling high flexibility and accuracy in adjusting the grinding fineness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a stepped adjustment mechanism is used for the grinding base, then the structure is simple and easy to manufacture, but the adjustment precision is insufficient and fine adjustment cannot be made
Solution Approach 1:
The patent replaces the traditional stepped mechanical adjustment mechanism with a thread-based mechanical system. The grinding base adjusting ring engages with threads on the guide ring, converting rotational motion into precise linear displacement. This thread mechanism enables continuous fine adjustment of the grinding base position, achieving high adjustment precision while maintaining mechanical simplicity.
Solution Approach 2:
The patent changes the adjustment parameter from discrete stepped positions to continuous linear displacement through the thread mechanism. By rotating the grinding base adjusting ring, the guide ring moves axially along the thread, allowing the grinding base position to be adjusted continuously rather than in fixed steps, thus achieving fine adjustment capability.
2Adaptability or versatility
If the grinding base is adjusted in stepped mode, then the adjustment mechanism is simple, but the grinding fineness control is limited
Solution Approach 1:
The patent replaces the stepped adjustment mechanism with a thread-based mechanical system that enables continuous adjustment. The grinding base adjusting ring threads onto the guide ring, allowing the user to rotate the adjusting ring to achieve any desired position within the adjustment range, providing versatile grinding fineness options while maintaining simple operational procedure.
Solution Approach 2:
The patent introduces dynamic adjustability by allowing continuous rotation of the grinding base adjusting ring, which translates to continuous axial movement of the guide ring through the thread mechanism. This dynamic adjustment capability enables the user to achieve any grinding fineness within the range, enhancing adaptability while keeping the operation simple and intuitive.
