Hand-Held Blender With Detachable Tools for Multi-Speed Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional hand blenders have single functions, are difficult to clean, and lack versatility in speed adjustment, as the stirring tool is typically non-detachable and requires separate machines for different functions and speeds.
Innovation Solution
A hand-held blender with a detachable body and multiple stirring tools, featuring a motor with a deceleration component using a planetary gear set for adjustable speed output, along with control levers for half speed and reverse operation, enabling easy tool interchange and multiple speed settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the stirring tool is made non-detachable from the body, then the structure is simpler and more compact, but the device becomes difficult to clean and lacks versatility
Solution Approach 1:
The blender is divided into two separable parts: a motor body and a stirring tool. The stirring tool can be detached from the body through a connection interface, allowing users to clean the tool separately or replace it with different tools for various functions. This segmentation resolves the contradiction by maintaining structural simplicity while enabling versatility through tool interchangeability.
2Adaptability or versatility
If a single machine is used for multiple functions with different speed requirements, then versatility is improved, but the speed control system becomes more complex
Solution Approach 1:
The patent implements a dynamic speed control system where the motor can operate at different speeds based on the attached tool. A speed detection device identifies the tool type and automatically adjusts the motor speed through a control circuit. This dynamic adjustment allows the single machine to handle multiple functions with different speed requirements without needing complex mechanical speed conversion mechanisms.
3Ease of operation
If the stirring tool is detached for cleaning or tool replacement, then versatility and ease of cleaning are improved, but the connection mechanism becomes more complex
Solution Approach 1:
The stirring tool is extracted as a separate, detachable component from the motor body. The connection interface includes simple coupling elements that allow easy attachment and detachment. This extraction principle enables users to remove the stirring tool for cleaning or replacement without complicating the overall structure, as the connection mechanism is designed to be simple and intuitive.
4Adaptability or versatility
If different tools are designed for different functions, then functionality is improved, but the overall device size and complexity increase
Solution Approach 1:
The motor body is designed as a universal platform that can accommodate multiple types of stirring tools through a standardized connection interface. Different tools (e.g., blending attachments, chopping tools, beating whisks) can be attached to the same motor body, allowing one device to perform multiple specialized functions without increasing the base device size. The tools themselves are compact and attach only when needed.

AI summary
The invention discloses a hand blender with a body which can connected with different stirring tools. The body includes a motor with an output shaft, a deceleration component and a plurality of output connectors. The speed control knob and the safety switch, starting switch which control the moving of the motor are set up of the body. The control circuit includes a half speed control lever and a reverse control lever which can be moved by the corresponding stirring tools. The hand blender can connected with different stirring tools and output different kinds of speeds. It is more convenient and safe.
