Detachable Mixer Handle Locking for Compact Transport Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mixers and power tools with protruding handles and output shafts occupy significant space during transportation and storage, making them inefficient for compact storage and transport.
Innovation Solution
Incorporation of a lock unit that allows the handle to be securely attached and detached from the body, enabling easy folding and compact storage, and a mechanism for electrical connection/disconnection with the handle, facilitating space-efficient transport and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the handle is fixed to the body, then the mixer is stable during operation, but the mixer occupies significant space during transportation and storage
Solution Approach 1:
The handle is divided into a detachable component that can be separated from the body. The handle includes a handle body and grips that can be attached to or removed from the main body, allowing the mixer to be disassembled into smaller segments for compact storage and transport while maintaining stability during operation when assembled.
Solution Approach 2:
The handle attachment system transitions from a fixed state to a detachable state. The lock unit mechanism allows the handle to be dynamically attached or detached based on operational needs, enabling the mixer to adapt between a stable assembled configuration during use and a compact disassembled configuration for storage.
2Ease of operation
If the handle protrudes largely from the body, then the operator has better grip and control, but the mixer requires more space for storage
Solution Approach 1:
The handle is segmented into a handle body and grips that can be detached from the main body. When not in use, the handle can be removed entirely, reducing the storage footprint to only the essential motor housing, while during operation, the full handle assembly provides optimal grip and control.
Solution Approach 2:
The handle is extracted as a separate removable component from the main body. This allows the handle to be taken out during storage to minimize space requirements, and attached during operation when grip and control are needed, effectively separating the storage and operational configurations.
3Volume of moving object
If the handle is detachable, then the mixer is compact for storage, but the attachment and detachment mechanism increases device complexity
Solution Approach 1:
The lock unit is designed to be automatically engaged when the handle is inserted into the body, and automatically disengaged when the handle is removed. This self-acting mechanism eliminates the need for separate locking operations, reducing operational complexity while maintaining secure attachment during use and enabling compact storage when detached.
Solution Approach 2:
The lock unit replaces complex multi-component fastening systems with a simpler mechanical locking mechanism. The lock unit uses a single locking element that can be actuated by a simple motion, reducing the number of parts and assembly steps compared to traditional bolt-and-nut or multiple-clamp systems.

AI summary
A mixer is transportable and storable without using much space. A mixer includes a body including a motor and an output shaft rotatable when driven by the motor, extending downward, and being connectable to a mixer shaft, a handle attachable to the body, and a lock unit located on the body. The lock unit is engageable with the handle at an attachment position of the handle to the body to lock the handle at the attachment position. The lock unit is operable to disengage from the handle to unlock the handle at the attachment position.
