Solution Overview

Problem

Existing manual household grinders are inefficient, prone to uneven rotation speed, require two hands to operate, and often become clogged due to adhesive condiments, leading to inconvenient cleaning and uneven discharging.

Innovation Solution

An electric grinder with a detachable housing, a driving device above the condiment bottle, a sweeping wheel to prevent blockages, and a guiding plate to ensure sanitary operation, allowing for one-handed use and uniform discharging.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual operation is used to rotate the grinding heads, then the grinder can be operated without additional power source, but the rotation speed is uneven and discharging is uncontrollable

Engineering Contradiction:
Improveoperation simplicityVSAvoidgrinding efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent replaces the manual mechanical rotation system with an electric motor-driven system. The motor provides consistent rotational speed through electrical power, eliminating the uneven rotation caused by manual operation. The grinding heads are rotated by a motor connected through a transmission mechanism, ensuring uniform and controllable discharging.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Device complexity

If two hands are required to operate the grinder, then the manual grinding mechanism can be simple, but it leads to waste of time and labor

Engineering Contradiction:
Improvegrinding mechanism simplicityVSAvoidgrinding time
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The patent replaces the manual two-handed operation with an electric motor-driven system. The motor automatically rotates the grinding heads at controlled speeds, eliminating the need for manual cranking or twisting motions. This reduces operation time significantly while the overall device structure remains relatively simple with the addition of just a motor and power source.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Quantity of substance

If the charging opening is exposed to adhesive condiments for long-term use, then the bottle capacity can be large, but the charging opening becomes blocked

Engineering Contradiction:
Improvecondiment capacityVSAvoidcharging smoothness
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The patent extracts the blocking problem from the charging opening by adding a sweeping wheel mechanism. The sweeping wheel, positioned near the charging opening, actively removes adhered condiments before they can block the opening. This allows the bottle to maintain large capacity while the charging opening remains clear and functional.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The sweeping wheel mechanism performs self-cleaning of the charging opening area. As the grinding heads rotate, the sweeping wheel continuously sweeps away adhered condiments, maintaining the charging opening clear without requiring external intervention or disassembly for cleaning.

Inventive Principle:
Principle #25Self-service

4Productivity

If the grinder components are in contact with adhesive condiments, then the grinding function can be effective, but cleaning becomes inconvenient

Engineering Contradiction:
Improvegrinding effectivenessVSAvoidcleaning convenience
Core Design Contradiction:
ProductivityVSEase of repair

Solution Approach 1:

The sweeping wheel provides continuous self-cleaning functionality, removing adhered condiments during normal operation. This prevents buildup on critical components, making subsequent cleaning much easier and more frequent maintenance unnecessary.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent designs the grinder with detachable components including the bottle, grinding heads, and housing sections. This segmentation allows easy disassembly for thorough cleaning of all surfaces that contact condiments, while during normal operation all components work together to achieve effective grinding.

Inventive Principle:
Principle #1Segmentation

AI summary

An electric grinder comprises a bottle (104), a housing, a grinding assembly and a driving device mounted inside the housing, the housing detachably connected to the bottle (104), the grinding assembly comprises a female grinding head (61) and a male grinding head (62), the driving device has an output engaged to a central driving rod (44), and the central driving rod (44) passes through the grinding cavity (61a) and drives the male grinding head (62). As the constancy overall volume of the grinder, the storage amount of condiments is relatively larger, the electric grinder has well-arranged and aesthetically-designed components and is reliable in use, with uniform electric grinding and uniform discharging.
