Blender Jar Detection and Motor Temperature Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Blenders lack a mechanism to ensure safe operation by preventing motor damage and user injury due to improper jar mounting, and they do not adapt easily to regional power standards, with users unaware of motor overheating issues that can reduce the blender's lifespan.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the blender operates without a jar properly mounted, then the blender can be used immediately, but the motor may be damaged or user injury may occur
Solution Approach 1:
The patent applies preliminary action by implementing a jar presence detection system that checks whether the jar is properly mounted before allowing the motor to operate. The sensor detects the jar's position in advance, and only when properly detected does the system enable motor operation. This prevents the motor from running without a jar, eliminating the risk of motor damage or user injury while maintaining ease of operation through automatic detection.
2Duration of action of stationary object
If the blender includes motor temperature monitoring, then the motor lifespan is extended, but the device complexity increases
Solution Approach 1:
The patent applies feedback by implementing a temperature monitoring system with visual indicators that continuously monitor motor temperature and provide real-time feedback to the user. When the motor temperature exceeds a predetermined threshold, the indicator alerts the user to stop use and allow cooling. This feedback mechanism prevents overheating damage, extending motor lifespan while keeping the system relatively simple through the use of straightforward temperature sensing and visual indication.
3Ease of manufacture
If the blender is designed for a specific regional cordset, then the construction is simplified, but the adaptability to different regions is reduced
Solution Approach 1:
The patent applies segmentation by separating the cordset from the main blender body, making the cordset a removable and replaceable component. This allows the blender to be manufactured with a standard mounting interface, and different regional cordsets can be attached as needed. The segmentation enables simplified construction of the main unit while providing adaptability to different regional power standards through interchangeable cordsets.
Solution Approach 2:
The patent applies universality by designing a standardized cordset mounting interface that can accommodate multiple types of cordsets from different regions. The base unit is constructed with universal mounting features that work with various cordset configurations, allowing a single blender design to serve multiple international markets without requiring region-specific manufacturing variations.

AI summary
A blender for blending foodstuff includes a base enclosing a motor and having an upper mounting surface. A jar sensor is secured to the base proximate the upper mounting surface and a jar is removably mountable to the base on the mounting surface. The jar includes a closed end and an actuator is mounted proximate the closed end. The jar sensor detects the presence of the actuator when the jar is mounted to the base in an operating position. The motor is powered when the jar sensor detects the presence of the actuator in the operating position. A motor temperature indicator is positioned on a control panel on the base and a temperature sensor is in communication with the motor temperature indicator. First and second cordsets are adaptable for removable mounting to the base for powering the motor.
