Solution Overview
Problem
There is a need for convenient and efficient systems to prepare nutritious foods that meet the World Health Organization's guidelines for healthy diets, requiring minimal processing steps, time, and effort while preserving nutrients, especially for on-site instant preparation of fruits, vegetables, seeds, and aquatic plants.
Innovation Solution
A compact handheld grinder that uses friction, shear, and pressure forces to crush and grind consumables into a liquid paste, featuring a container with a grinder housing that includes nip roller pairs with adjustable distances and speeds, and a motor-driven system for efficient processing without generating waste, designed to fit within a user's hand for portability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional juicing systems are used, then processing capability is achieved, but device size and portability are compromised
Solution Approach 1:
The grinding mechanism is nested within the container structure, with the container serving as both storage and processing chamber. The lid integrates the grinding assembly, allowing the entire system to collapse into a compact form when not in use, fitting within a user's hand while maintaining full processing capability.
Solution Approach 2:
The patent combines multiple functions into unified components: the container serves as both storage and processing chamber, the lid integrates the grinding mechanism, and the output channel serves dual purposes for juice extraction and waste removal. This merging eliminates the need for separate processing units, achieving portability without sacrificing productivity.
2Productivity
If traditional grinding mechanisms are used, then grinding effectiveness is achieved, but ease of operation is compromised
Solution Approach 1:
The system employs self-regulating mechanisms where the grinding process automatically controls material flow through the container. The grinding mechanism itself regulates the flow rate based on processing needs, eliminating the requirement for manual flow control and simplifying user operation while maintaining effective grinding.
Solution Approach 2:
The device handles multiple material types (fruits, vegetables, seeds, aquatic plants) through a single unified grinding mechanism, eliminating the need for different tools or complex adjustments. The same mechanism effectively processes diverse materials, making operation simple while maintaining grinding effectiveness.
3Device complexity
If single-output systems are used, then simplicity is achieved, but loss of substance increases
Solution Approach 1:
The system extracts and separates consumable paste from waste products through distinct output channels. The waste removal channel specifically extracts non-consumable material while the consumable output channel delivers usable paste, preventing waste contamination and enabling complete utilization of consumable materials while maintaining system simplicity.
Solution Approach 2:
The dual-channel output system enables selective discarding of waste products through one channel while recovering and preserving consumable paste through another. This separation ensures that no consumable material is lost to waste streams, maximizing substance utilization while keeping the system structurally simple.
4Productivity
If rapid processing is used, then productivity is improved, but temperature increase and nutrient loss occur
Solution Approach 1:
The patent replaces high-speed mechanical cutting systems with a friction-based grinding mechanism using nip rollers. This mechanical substitution generates minimal heat compared to blade-based systems, enabling rapid processing while preventing temperature increase that would cause nutrient loss, achieving both productivity and nutrient preservation.
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
The system effectively processes a variety of nutritious foods into a liquid paste or juice with minimal waste, preserving nutrients and allowing for on-demand, portable preparation of healthy meals, aligning with the WHO guidelines by promoting the consumption of fresh fruits and vegetables.
Implementation Method 1
The grinder includes a crushing and grinding mechanism that uses friction forces to grind the consumables into a rough or fine liquid paste
Implementation Method 2
The grinder includes a crushing and grinding mechanism that uses shear forces to grind the consumables into a rough or fine liquid paste
Implementation Method 3
The grinder includes a crushing and grinding mechanism that uses pressure (e.g., hydraulic pressure) to grind the consumables into a rough or fine liquid paste

AI summary
A compact cold press grinder that fits within a user's hand that includes a cold press grinder and a container that holds consumables, such as fruits, vegetables, seeds, aquatic plants, and/or other nutritious consumable. The cold press grinder crushes and grinds the consumables to a liquid paste or juice using friction forces, shear forces and pressure (e.g. hydraulic press). The cold press grinder includes a housing that is removably attachable to the container. The cold press grinder may include an input for receiving the consumables within the container and a plurality of nip roller pairs that grind the consumables. The cold press grinder has one output to output the consumable as is or the liquid paste or the juice prepared by the cold press grinder and does not include an output to output consumable waste products.
