Solution Overview

Problem

Existing food processor tools with rotatable machining tools are bulky and heavy, occupying significant storage space due to separate drive rods for each tool, which is inefficient in terms of space and material usage.

Innovation Solution

A detachable and non-rotatable connecting element between the processing element and drive rod allows for shared use of a single drive rod across multiple processing tools, reducing the need for separate drive rods and minimizing storage space and weight.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate drive rods are used for each processing tool, then each tool can be independently operated, but the storage space and weight of the tool set increase significantly

Engineering Contradiction:
Improvetool independenceVSAvoidstorage space
Core Design Contradiction:
Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The patent implements a universal drive rod design that can be used with multiple different processing tools (whisk, beater, stirring loop, kneading hook, strainer). The drive rod includes a standardized connection element that interfaces with various tool types, allowing a single drive rod to perform multiple functions across different processing operations, thereby eliminating the need for separate drive rods for each tool.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines the drive rod functionality with a standardized connection system that integrates multiple tool interfaces into a single unified component. The connection element on the drive rod is designed to accommodate different tool attachments, merging what would traditionally be separate drive rod designs into one versatile component that reduces overall tool set volume.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If separate drive rods are used for each processing tool, then each tool can be independently operated, but the weight of the tool set increases

Engineering Contradiction:
Improvetool independenceVSAvoidtool set weight
Core Design Contradiction:
Adaptability or versatilityVSWeight of stationary object

Solution Approach 1:

The universal drive rod design allows one drive rod to replace multiple separate drive rods, each weighing a certain amount. By creating a single multi-functional drive rod that can attach to various processing tools, the overall weight of the tool set is reduced while maintaining the ability to operate different tools independently.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The detachable connection system allows users to discard (remove) processing tools that are no longer needed and recover (retain) the universal drive rod for use with other tools. This separation enables the drive rod to be reused across multiple tools rather than being permanently attached to each individual tool, reducing redundant weight in the tool set.

Inventive Principle:
Principle #34Discarding and recovering

3Adaptability or versatility

If multiple separate drive rods are included in the tool set, then each processing element can be independently driven, but the complexity of the tool set increases

Engineering Contradiction:
Improveprocessing element independenceVSAvoidtool set complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The standardized connection element on the drive rod provides a universal interface that simplifies the tool set architecture. Instead of having unique drive rod designs for each processing element, the universal connection system allows any processing tool to be attached to the same drive rod, reducing the number of unique components and simplifying the overall device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent segments the tool set into modular components: a universal drive rod with a standardized connection element, and various detachable processing tools. This segmentation allows each component to be independently designed and manufactured, then assembled through the standardized connection interface, reducing overall system complexity compared to integrated designs.

Inventive Principle:
Principle #1Segmentation
