Solution Overview

Problem

Food processors have a bulky structure with multiple components, making them difficult to store efficiently, as consumers typically separate the lid and other parts, leading to space-consuming storage solutions.

Innovation Solution

A food processor lid designed to be inverted and fit comfortably with the container, allowing all components to be stored together, with the lid's annular ledge and food chute configuration enabling compact storage by accommodating the processing tools within the container.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the food processor components are stored separately, then each component can be easily accessed, but the total storage space required increases significantly

Engineering Contradiction:
ImproveEase of access to componentsVSAvoidStorage space
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The lid is designed to function as a storage container for all food processor components. The food chute extends into the container interior, creating a recess that accommodates the processing tools. This merging of the lid with the storage function allows all components to be stored together in a single compact unit, reducing the total storage space required while maintaining easy access when needed.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The processing tools are nested within the container interior, specifically within the food chute recess. The food pusher and other components fit inside the container when not in use, similar to nested dolls. This nesting arrangement allows multiple components to occupy the same space efficiently, minimizing the overall storage footprint.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of operation

If the food chute extends perpendicularly from the lid, then food can be easily added during operation, but the lid becomes difficult to store with other components

Engineering Contradiction:
ImproveEase of food additionVSAvoidLid configuration
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The food chute is designed to extend in the opposite direction during storage - instead of extending outward from the lid, it extends into the container interior when the lid is inverted. This inversion allows the lid to be stored compactly with the food chute recess accommodating the processing tools inside the container, while during operation the chute still provides easy food access from the top.

Inventive Principle:
Principle #13The other way round (Inversion)

3Adaptability or versatility

If the food processor has a bulky structure with multiple components, then it provides comprehensive processing functionality, but it becomes unwieldy to store when not in use

Engineering Contradiction:
ImproveProcessing functionalityVSAvoidStorage volume
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The lid serves multiple functions: it covers the container during operation, provides a food chute for adding ingredients, and acts as a storage container for all processing tools when not in use. The container interior serves dual purposes as both the processing chamber and the storage space for accessories. This multi-functionality reduces the need for separate storage components, minimizing overall storage volume while maintaining comprehensive processing capabilities.

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

AI summary

A food processor includes a base, a container having a side wall and an open end including a rim, and a lid for engaging the open end of the container in an operating position and a storage position. The lid has a top wall with a first and second principal surface, an annular ledge with a first and second side, and a food chute extending from the first principal surface generally parallel to a longitudinal axis of the top wall. The food chute has a length and extends away from the container with the second side of the annular ledge contacting the rim of the container when the lid is in the operating position. When the lid is in the storage position, the food chute extends into an interior of the container with the first side of the annular ledge contacting the rim of the container.
