Solution Overview

Problem

Existing food processors require multiple drive units for different processing tools and containers, leading to clutter and space issues in kitchens, as they are not adaptable to various modes of operation or orientations.

Innovation Solution

A food processing apparatus with a drive unit that can operate in multiple modes and orientations, using different activation sites and container designs, allowing it to support various processing tools and containers, and featuring alignment features for proper alignment and actuation mechanisms to prevent unintended activation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple drive units are used for different processing tools and containers, then each tool can be operated reliably, but kitchen clutter and space consumption increase

Engineering Contradiction:
Improveoperational reliabilityVSAvoidkitchen space
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The drive unit is designed to perform multiple functions by supporting different container types (blending containers with lids and food processing containers without lids) and processing tools through a universal interface mechanism. The drive unit can be coupled to various containers using the same basic coupling structure, allowing one drive unit to replace multiple specialized drive units.

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

2Adaptability or versatility

If the drive unit is designed to work with multiple container types, then versatility is improved, but the risk of unintended activation increases

Engineering Contradiction:
Improvecontainer compatibilityVSAvoidunintended activation
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

Different activation mechanisms are provided for different container types: a lid-actuated activation mechanism for blending containers with lids, and a bottom-surface actuation mechanism for food processing containers without lids. The drive unit selectively engages the appropriate activation mechanism based on which container type is coupled to it, ensuring that activation only occurs when properly intended.

Inventive Principle:
Principle #3Local quality

3Device complexity

If a single activation site is used for all modes of operation, then device complexity is reduced, but ease of operation deteriorates due to activation difficulties in certain orientations

Engineering Contradiction:
Improveactivation mechanism complexityVSAvoidactivation ease
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The activation mechanism is designed to accept input from multiple dimensions: the lid can actuate the mechanism from above when the drive unit is in a horizontal orientation, while the bottom surface can actuate the mechanism from below when the drive unit is in a vertical orientation. This multi-directional activation capability allows easy operation regardless of the drive unit's orientation.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Adaptability or versatility

If the drive unit supports multiple orientations, then adaptability is improved, but ensuring proper alignment becomes more difficult

Engineering Contradiction:
Improveorientation flexibilityVSAvoidalignment precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

Alignment features are provided on both the drive unit and the container that guide proper alignment before final coupling occurs. These preliminary alignment elements ensure that the drive unit and container are properly aligned in the correct orientation before the coupling mechanism engages, making it easier to achieve proper alignment even when multiple orientations are supported.

Inventive Principle:
Principle #10Preliminary action

AI summary

A food processing apparatus is disclosed and comprises: a drive unit configured to drive a processing tool; a first activation site to permit actuation of the drive unit; a first container; and a second container. The drive unit is useable in a first mode of operation with the first container and is useable in a second mode of operation with the second container. In the first mode of operation, the first activation site is accessible by a user, and in the second mode of operation, a user is prevented from interacting with the first activation site when the drive unit is placed in an upright position on a flat support surface.
