Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a growing demand for preparing nutritious food from raw products without industrial processing, and existing appliances are not adequately designed for efficiently grinding oil-containing hard produce at home.
Innovation Solution
A compact appliance with coaxial circular grinding members, featuring grooved faces and a collection zone, designed for grinding oil-containing seeds like sesame or peanuts, allowing for efficient extraction of oily substances with easy cleaning and interchangeable grinding pairs for different produce types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional grinding appliances are used, then grinding function is provided, but they are not efficiently designed for oil-containing hard produce and are difficult to clean
Solution Approach 1:
The patent extracts the grinding function into a separate, removable capsule that can be easily detached from the main appliance body. This capsule contains the grinding elements and the collected oily substance, allowing users to simply remove and empty the capsule rather than disassembling and cleaning the entire appliance, thereby dramatically improving cleaning ease while maintaining grinding efficiency
Solution Approach 2:
The appliance is segmented into distinct functional modules: a main body housing the motor and control systems, and a separate removable capsule containing the grinding elements and collection chamber. This segmentation allows the grinding components to be isolated for easy cleaning and maintenance without affecting the main appliance structure
2Adaptability or versatility
If existing grinding appliances are used, then basic grinding is achieved, but they lack specialized design for oil extraction from hard seeds
Solution Approach 1:
The grinding elements within the capsule are specifically designed with local quality features optimized for oil-containing hard seeds, including grooved surfaces and specific geometries that facilitate both grinding and oil extraction. The collection chamber is also specifically shaped to accumulate oily substances, providing specialized functionality without requiring multiple different appliances
3Volume of moving object
If compact design is implemented for home use, then appliance size is reduced, but grinding zone accessibility may be limited
Solution Approach 1:
The capsule is designed with dynamic features including a rotatable cap that opens for loading produce and a removable structure that allows access to the grinding zone. This dynamic design enables easy produce feeding and cleaning in a compact form factor, as the opening and closing mechanisms are integrated into the capsule structure itself rather than requiring external access points
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

AI summary
The present disclosure discloses an appliance, suitable for home use, for grinding oil-containing hard produce, in particular oil-containing seeds, to therefore extract an oily substance product. For example, the appliance may grind sesame to obtain Tahini, or peanuts/almonds to obtain butter therefrom. The present disclosure further discloses a capsule to be received in a grinding appliance such as disclosed herein. The appliance incudes two grinding members, configured to grind the hard produce. Each grinding member has a grooved face that is patterned to be configured for grinding. The hard produce is grinded in the interface defined between the two grooved faces, defining a grinding zone. The grinding members typically have a shape of a circle and are aligned one with the other along a common axis. At least one of the grinding members is configured to rotate about the axis to perform the motion carrying out the grinding in the interface between the members. The hard produce is introduced into the grinding zone via one or more openings in at least one of the grinding members. The openings lead directly into the grinding zone, namely the hard produce that is fed through the openings reaches to a part of one of the grooved faces to initiate the grinding process. The grinding zone is constituted by two grinding portions, an inner grinding portion and a peripheral grinding portion, defining inner grinding zone and peripheral grinding zone, respectively. A peripheral collection zone is disposed peripheral to the peripheral grinding zone and is configured to collect the grinded oily substance product that radially flows from the peripheral grinding portions. The oily substance in the collection zone flows towards a substance collector, through which the oily substance flows for being collected.
