Solution Overview

Problem

Kitchen appliances face challenges in accurately measuring properties like temperature during food and beverage preparation due to difficulties in positioning sensors close to the mixing content without interfering with the mixing process, especially with rotating attachments and removable bowls.

Innovation Solution

Incorporating temperature sensors into the attachments that rotate within the mixing bowl, allowing them to be in direct contact with the content and using wireless power transfer to power the sensors, which are positioned to withstand the mechanical and thermal stresses of the mixing action, enabling accurate temperature measurement and control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If temperature sensors are positioned close to the mixing content to enable accurate temperature measurement, then measurement precision is improved, but the sensors may interfere with the mixing process or be damaged by mechanical and thermal stresses

Engineering Contradiction:
Improvetemperature measurement accuracyVSAvoidsensor durability and non-interference
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The temperature sensor is integrated into the mixing attachment itself, combining the sensing function with the mixing function. This allows the sensor to be positioned in direct contact with the mixing content for accurate measurement while being protected by the attachment structure from mechanical damage and thermal stresses

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The sensor is pre-positioned and secured within the attachment structure before the mixing process begins. This preliminary positioning ensures the sensor is correctly placed for accurate measurement and is pre-protected from potential damage during operation

Inventive Principle:
Principle #10Preliminary action

2Measurement precision

If sensors are integrated into rotating attachments to enable direct contact with content, then measurement precision is improved, but the complexity of providing power and data transmission increases

Engineering Contradiction:
Improvetemperature sensing accuracyVSAvoidwireless power transfer and data transmission system
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces traditional mechanical wiring and power transmission systems with wireless power transfer and wireless data transmission technologies. This eliminates the complexity of rotating connections, sliding contacts, and mechanical power transmission to rotating sensors

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The attachment structure is designed to perform multiple functions: mixing, housing the temperature sensor, and enabling wireless power and data transmission. This multi-functionality reduces the need for separate systems and simplifies the overall device architecture

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