Solution Overview

Problem

Manufacturers face high costs due to the need for a diverse range of tools for different kitchen appliances, and users must purchase separate sets of tools for each device, as existing devices are often used for similar tasks but require distinct tools.

Innovation Solution

A kitchen appliance set where system tools can be coupled to multiple drive devices, allowing the same tool to be used across various appliances, such as hand blenders and mixers, reducing the need for multiple tool sets.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manufacturers offer a diverse range of tools for different drive units, then each drive unit can be used for various tasks, but production and distribution costs increase significantly

Engineering Contradiction:

Improvetask versatility of drive unitsVSAvoidproduction and distribution costs

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent implements a universal coupling system where tools designed for one type of drive unit (hand mixer or hand blender) can be attached to and used with the other type. This is achieved through standardized coupling mechanisms that allow cross-compatibility, enabling a single tool to serve multiple functions across different drive unit types, thereby reducing the need for manufacturers to produce and distribute separate tool sets for each drive unit category.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If users purchase separate tool sets for each drive unit, then each drive unit has dedicated tools, but the total cost for users increases

Engineering Contradiction:

Improvededicated tool functionalityVSAvoidtotal number of tools to purchase

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent enables users to purchase a single set of tools that can be used with multiple types of drive units. The universal coupling system allows tools to be interchangeably attached to different drive unit types, eliminating the need for users to buy separate tool sets for each drive unit while maintaining full functionality and versatility across all drive units.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of manufacture

If manufacturers consolidate tool ranges, then production costs decrease, but users need tools that work with multiple drive unit types

Engineering Contradiction:

Improveproduction cost efficiencyVSAvoidcross-drive unit compatibility

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent achieves both cost efficiency and cross-compatibility through a universal coupling system. Manufacturers can consolidate their tool ranges into a single standardized line that works across multiple drive unit types, reducing production complexity and costs. Simultaneously, the universal coupling design ensures that these consolidated tools maintain full adaptability and versatility when used with different drive unit types, satisfying both manufacturing and user needs.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A kitchen appliances set (1), especially for domestic or commercial use, comprises one or more system attachments (14, 15, 16) and at least two system drive devices of different type, every system attachment (14, 15, 16) being detachbly connectible to every system drive device (2, 3) in order to be driven by it. The system drive devices are e.g. a hand blender and a hand mixer. The invention removes the need for keeping a separate set of attachments for every drive device.
