Solution Overview

Problem

Existing blenders face issues with detecting the closure of the container lid reliably and efficiently, often requiring separate components that can be contaminated, limiting design flexibility, and consuming high power, especially when using wireless communication or electromagnetic induction methods.

Innovation Solution

A blender design that utilizes conductor sets on the main body and container body for current transmission to detect lid closure, allowing detection in any orientation and maintaining transparency, with removable conductors and low power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a traditional blender with a fixed blade assembly is used, then the structure is simple and easy to manufacture, but the blender cannot be easily cleaned and cannot accommodate different blending needs

Engineering Contradiction:
Improveblending versatilityVSAvoidblade assembly complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The blade assembly is divided into multiple detachable blade elements that can be separated from the blending cup. This segmentation allows each component to be easily cleaned individually and enables different blade configurations to be used for different blending tasks, thereby increasing versatility while maintaining ease of cleaning.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The blade assembly is designed to be dynamically configurable, allowing users to attach or detach blade elements as needed. This dynamic design enables the blender to adapt to different blending requirements (e.g., blending, chopping, mixing) while keeping the overall structure relatively simple through modular components.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If a traditional blender with a bottom-drain design is used, then the structure is simple, but the blender cannot easily dispense blended products and creates cleaning difficulties

Engineering Contradiction:
Improveproduct dispensing easeVSAvoidcup structure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The dispensing system is segmented into a separate dispensing mechanism that can be attached to or detached from the blending cup. This allows the cup to maintain a simple bottom-drain structure for easy cleaning while enabling controlled product dispensing through the separate mechanism, improving ease of operation without significantly increasing overall complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

An intermediary dispensing mechanism is introduced between the blending cup and the container. This intermediary component enables controlled product dispensing while keeping the blending cup structure simple and easy to clean, as the complex dispensing functionality is isolated in a separate attachable component.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of repair

If a fixed blade assembly is used in a traditional blender, then the manufacturing process is simple, but the blade assembly cannot be easily detached for cleaning

Engineering Contradiction:
Improvecleaning easeVSAvoidassembly manufacturing ease
Core Design Contradiction:
Ease of repairVSEase of manufacture

Solution Approach 1:

The blade assembly is segmented into multiple detachable blade elements that can be easily separated from the blending cup through simple attachment mechanisms. This segmentation enables easy detachment for cleaning while maintaining manufacturing simplicity through standardized, modular components that can be produced using conventional manufacturing processes.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The blade elements are pre-configured with attachment features that enable quick connection and detachment without requiring complex assembly or disassembly procedures. This preliminary design of the attachment mechanism facilitates easy cleaning by allowing rapid blade removal while keeping the manufacturing process straightforward through standardized components.

Inventive Principle:
Principle #10Preliminary action

AI summary

Proposed is a blender (1) in which when the closure of a container lid (20) of a container body (10) is detected, a main body (30) operates. In the blender (1), when the closure of the container lid (20) of the container body (10) is detected, current is transmitted from a first conductor set (100) of the main body (30) to a second conductor set (200) of the container body (10), and when the current transmitted through the second conductor set (200) is detected, the main body (30) recognizes the closure of the container lid (20) of the container body (10) and operates.
