Solution Overview

Problem

Blenders suffer from sagging of the upper surface casing, leading to malfunction and decreased manipulation sensitivity due to heat generation in electronic parts and inadequate support, resulting in inaccurate user input and potential errors.

Innovation Solution

A support member is provided under the upper surface of the main body casing to prevent sagging, and a touch module is supported to enhance manipulation precision, with air circulation designed to dissipate heat away from the user.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If electronic parts (motor assembly and PCB module) are installed in the main body to enable blender operation, then the blender functionality is improved, but heat is generated causing malfunction and reduced reliability

Engineering Contradiction:
Improveblender functionalityVSAvoidoperational reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent converts the harmful heat generated by electronic parts into a beneficial cooling effect by designing an air circulation path where air flows through the PCB module and motor assembly, absorbing heat and dissipating it outside, thus preventing overheating and malfunction

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

2Ease of manufacture

If the upper surface of the main body casing is made flexible or thin to improve manufacturing ease, then manufacturing is simplified, but the casing sags under pressure causing manipulation errors and malfunction

Engineering Contradiction:
Improvecasing manufacturingVSAvoidmanipulation accuracy
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent segments the main body casing into an upper casing and a lower casing, with the support member positioned between them to provide structural reinforcement. This segmentation allows the upper surface to remain thin and easy to manufacture while preventing sagging through the intermediate support structure

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The support member acts as an intermediary element between the upper and lower casings, providing mechanical support to prevent sagging of the upper surface while maintaining the overall structure's integrity and ease of manufacture

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If the PCB module is placed under the manipulation part to reduce device complexity, then the structure is simplified, but the manipulation sensitivity decreases and input accuracy is reduced

Engineering Contradiction:
Improvestructural complexityVSAvoidmanipulation sensitivity
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent positions the PCB module in a different spatial dimension (under the manipulation part) rather than directly beneath it, allowing the manipulation part to maintain its sensitivity while the PCB is supported by the lower casing structure, thus reducing complexity without sacrificing precision

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

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
