Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing kitchen grinders require distinct designs and components for different functions, leading to increased manufacturing costs and user adaptability issues, as well as the need for full device replacement when the grinding mechanism wears out.
Innovation Solution
A modular grinding core with a housing, rasp support member, and grind block member that can be adapted to various external grinding devices and rasps, featuring a coupling adapter and adjustable gap mechanism for versatile grinding applications, reducing the need for multiple device designs and allowing for easy replacement of worn parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If distinct working portions are designed for distinct grinders, then grinding functionality is optimized, but manufacturing cost and device complexity increase
Solution Approach 1:
The patent applies universality by designing a standardized interface and housing structure that can accommodate multiple different working portions (rasps, grind blocks, milling elements) within a single grinder body. The coupling adapter provides a universal connection mechanism that allows different grinding elements to be interchangeably mounted, enabling one grinder to perform multiple grinding functions without requiring distinct designs for each function.
2Adaptability or versatility
If distinct working portions are designed for distinct grinders, then grinding functionality is optimized, but manufacturing cost increases
Solution Approach 1:
The patent applies segmentation by separating the grinder into distinct modular components: a reusable housing with actuation mechanism, and replaceable working portions (rasps, grind blocks, milling elements). This segmentation allows the expensive housing and actuation mechanism to be manufactured once and reused, while only the simpler working portions need to be manufactured in various configurations. The standardized coupling adapter serves as an interface that connects different working portions to the same housing, reducing overall manufacturing costs.
3Reliability
If the working portion wears out, then the entire grinding product must be replaced, but this increases loss of substance and cost
Solution Approach 1:
The patent applies discarding and recovering by enabling the working portion to be separately replaced when worn, while recovering and reusing the housing, actuation mechanism, and coupling adapter. The modular design with standardized interfaces allows users to detach the worn working portion and attach a fresh one without discarding the main grinder body, thereby reducing material waste and extending the overall product lifecycle.
4Adaptability or versatility
If users must adapt to various grinders with different working portions, then grinding functionality is optimized, but ease of operation decreases
Solution Approach 1:
The patent applies universality by providing a standardized coupling adapter and interface design that remains consistent across different grinder models and working portion types. Users learn to operate the actuation mechanism once, and this operation transfers to all working portions mounted on the same housing, reducing the learning curve and improving ease of operation while maintaining versatility.

AI summary
A modular grinding core includes a housing configured to be operatively installed in a variety of external grinding devices, a rasp support member having a coupling adapter configured to be operatively coupled to an actuation mechanism of a first external grinding device at a first time and to an actuation mechanism of a second external grinding device at a second time after being removed from the first external grinding device. The rasp support member includes a receptacle configured to removably receive any one of a variety of rasps. The rasp support member is configured to reciprocate in response a force exerted by the external grinding device. The modular grinding core further includes a grind block member resisting displacement of the food items or spices away from the rasp support member, and an adjustment mechanism allowing a user to adjust a gap between the grind block and rasp support members.
