Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional food waste disposers face issues with tiny debris getting stuck in the gap between knocking blocks and the disk base, leading to operational inefficiencies and the need for frequent dismantling for maintenance.
Innovation Solution
A grinding disk design featuring a knocking disk base, a long strip knocking plate, and movably mounted knocking blocks with cushion blocks and pivotally connected heads, allowing for sliding and rotating motion to prevent debris entrapment, with rivets inserted through slots for secure mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If knocking blocks are movably connected to the disk base via rivets to enable rotation and hammering motion, then the hammering function is improved, but tiny debris can become stuck in the gap between knocking blocks and disk base, causing operational failure
Solution Approach 1:
The invention extracts the harmful factor (debris) from the system by providing a through-hole in the disk base that allows debris to be removed from the gap between the knocking block and disk base, preventing operational failure while maintaining the hammering function
Solution Approach 2:
The invention segments the disk base structure by creating a through-hole that divides the space, allowing the gap between the knocking block and disk base to be cleared of debris, thus maintaining reliable operation without compromising the hammering mechanism
2Volume of moving object
If the disposer structure is made compact for small disposer applications, then the size is reduced, but the complexity of the grinding mechanism increases
Solution Approach 1:
The invention merges multiple functions into a single integrated knocking block assembly that combines the hammering mechanism with a built-in through-hole for debris removal, eliminating the need for separate cleaning mechanisms and reducing overall device complexity while maintaining compact size
Solution Approach 2:
The knocking block is designed with multi-functionality, serving both as the hammering element and as a structure that facilitates debris removal through its integrated through-hole, thereby reducing the number of separate components needed in the compact disposer
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents debris from becoming stuck, ensuring continuous operation and reducing maintenance needs by allowing easy removal of debris during rotation, enhancing the functionality and reliability of the food waste disposer.
Implementation Method 1
the cushion block of the knocking block drives the knocking block head to slide, such that the knocking block head rotates about the rivet to hammer an object
Implementation Method 2
the knocking block head rotates about the rivet to hammer an object, and the cushion block pivotally connected to the cushion block can move up and down and hammer the object while rotating and sliding

AI summary
A grinding disk used for a food waste disposer includes a knocking disk base, a long strip knocking plate, at least two knocking blocks and rivets. The long strip knocking plate is arranged on the lower surface of the knocking disk base. The knocking blocks are movably and symmetrically mounted to the knocking disk base via the rivets, and each knocking block includes a cushion block for connection of the rivets and a knocking block head pivotally connected to the cushion block. When the knocking disk base is rotated with the shaft of an electric motor, the cushion block of the knocking block drives the knocking block head to slide, such that the knocking block head rotates about the rivet to hammer an object, and the cushion block can also move up and down and hammer the object while rotating and sliding.
