Solution Overview

Problem

Blenders often malfunction due to heat generation in electronic parts, decreased manipulation sensitivity, and the absence of a system to remove static electricity, leading to inaccurate user input and potential sagging of the outer casing.

Innovation Solution

A blender with a discharge system that connects multiple metal parts to a ground bracket to collect and remove static electricity, preventing malfunctions and improving user interaction by enhancing manipulation precision and preventing sagging.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If multiple metal parts are used in the blender main body, then structural integrity and durability are improved, but static electricity accumulates causing malfunctions

Engineering Contradiction:

Improvestructural integrityVSAvoidmalfunction prevention

Core Design Contradiction:

StrengthVSReliability

Solution Approach 1:

A discharge member made of conductive material is introduced as an intermediary element to connect multiple metal parts to a ground bracket. This mediator provides a controlled path for static electricity to flow to ground, preventing accumulation and malfunctions while preserving the structural benefits of multiple metal components.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The electrical parameter of the metal parts is changed by connecting them to ground through the discharge member. This alters the electrical state from isolated (prone to static accumulation) to grounded (static dissipated), resolving the contradiction between maintaining metal structure and preventing static-induced malfunctions.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If electronic parts are used for motor assembly and PCB module, then blender functionality is improved, but heat generation causes malfunction

Engineering Contradiction:

Improveblender functionalityVSAvoidheat generation

Core Design Contradiction:

Adaptability or versatilityVSTemperature

Solution Approach 1:

Heat is extracted from the electronic parts through a dedicated heat dissipation structure. The cooling fan and heat dissipation fins separate the thermal management function from the electronic components, allowing the blender to maintain full functionality while actively removing excess heat that would cause malfunctions.

Inventive Principle:

Principle #2Taking out (Extraction)

3Ease of operation

If touch button manipulation part is used, then user interface modernization is improved, but manipulation sensitivity decreases due to PCB movement

Engineering Contradiction:

Improveuser interface modernizationVSAvoidmanipulation sensitivity

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The PCB module is preliminarily fixed to the main body using reinforcing ribs before the touch button manipulation part is assembled. This preliminary strengthening action prevents PCB movement during operation, ensuring that touch inputs are accurately transmitted without sagging or misalignment, thus maintaining high manipulation sensitivity.

Inventive Principle:

Principle #10Preliminary action

4Ease of operation

If outer casing is made flexible for user comfort, then ease of handling is improved, but sagging occurs causing malfunction

Engineering Contradiction:

Improveease of handlingVSAvoidcasing stability

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The outer casing is constructed as a composite structure combining flexible material for user comfort with rigid reinforcing ribs for structural stability. This composite design allows the casing to be easily handled while preventing sagging that would cause malfunction, as the reinforcing ribs provide the necessary structural support within the flexible casing.

Inventive Principle:

Principle #40Composite materials
