Solution Overview
Problem
Existing grinding machines face issues with cleaning due to non-removable structures and high manufacturing costs and complexity with detachable designs, leading to safety concerns and user dissatisfaction.
Innovation Solution
A grinding machine with an integrated double-disc structure and an assembling method where the upper and lower grinding discs are fixed on a sealing base, allowing for easy disassembly and cleaning, and reducing assembly accuracy issues through a precise positioning system with elastic sealing pieces and adjustable components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the grinding structure is fixed non-removably at the bottom of the container, then the machine is easy to produce and process, but it is not easy to clean and food residues cannot be removed
Solution Approach 1:
The grinding structure is divided into an upper grinding disc and a lower grinding disc that can be separated from each other and from the container. The lower grinding disc is detachably connected to the container, while the upper grinding disc is detachably connected to the lower grinding disc, enabling complete disassembly for thorough cleaning of all surfaces.
2Ease of operation
If the grinding structure is made detachable with separate blade and grinding discs, then it is easy to clean, but the assembly complexity increases and manufacturing costs rise
Solution Approach 1:
The grinding structure is segmented into detachable components (container, lower grinding disc, upper grinding disc) that can be easily separated for cleaning and reassembled for use, balancing cleanliness requirements with manageable assembly complexity.
Solution Approach 2:
The grinding discs are designed with dynamic connection mechanisms (snapping structures, positioning steps, elastic sealing pieces) that allow easy attachment and detachment while maintaining stability during operation, reducing the perceived complexity for users.
3Reliability
If ultrasonic welding is used to fix the upper grinding disc to the container, then the assembly is secure, but thermal expansion differences cause the disc to fall off and affect mutual movement
Solution Approach 1:
An elastic sealing piece is introduced as an intermediary between the upper grinding disc and the lower grinding disc/container. This elastic component compensates for thermal expansion differences and maintains secure connection without the harmful effects of ultrasonic welding, preventing the disc from falling off while allowing for material expansion.
4Reliability
If the grinding discs are arranged with large gap for safety, then safety is improved, but the grinding efficiency decreases and the machine size increases
Solution Approach 1:
The positioning mechanism allows the grinding discs to be precisely positioned at optimal distances during operation, maintaining safety while maximizing grinding efficiency. The dynamic adjustment capability enables the gap to be optimized for each grinding task rather than being fixed at a conservative large distance.
