Portable Blender with Nested Base Design for Battery-Powered Blending
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blenders are either not powerful enough or not portable, lacking the functionality and flexibility of AC-powered blenders, with battery-powered options being too small and inefficient for blending solid foods.
Innovation Solution
A portable blender system with a lithium-ion battery pack that can blend over 200 servings of frozen drinks on a single charge, featuring a brushless direct current motor, solid-state motor control, and a compact design that allows the base to be stored inside the jar, along with auto-reverse functionality to clear jams and infinitely variable speed control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If battery-powered blenders are made compact and portable, then portability is improved, but blending power and functionality deteriorate
Solution Approach 1:
The base unit is designed to nest inside the blending jar when not in use, creating a compact portable configuration. The jar serves as both the blending container and the storage housing for the motor and battery components, eliminating the need for separate carrying cases while maintaining full blending functionality.
2Power
If AC-powered blenders are used to maintain full power, then blending power is maintained, but portability and flexibility deteriorate
Solution Approach 1:
The AC-powered mechanical system is replaced with a battery-powered electric motor system. The brushless direct current motor with solid-state control provides equivalent blending power to AC models while eliminating the need for electrical outlets, enabling true portability and flexibility for use anywhere.
3Power
If battery capacity is increased to provide full power, then blending power is improved, but device size and weight increase
Solution Approach 1:
The motor system uses a brushless direct current motor with solid-state control that provides high power output relative to its size. This motor technology, combined with an optimized battery pack, delivers full-blending power while keeping the overall weight manageable for portable use, unlike traditional AC motors that would require much heavier power supplies.
4Volume of moving object
If compact design is implemented to improve portability, then storage space is reduced, but motor power and battery capacity are limited
Solution Approach 1:
The motor system incorporates variable speed control with multiple power levels, allowing the compact motor to deliver both high-power bursts for tough blending tasks and lower-power operation for lighter tasks. This dynamic power adjustment maximizes the utility of the compact motor design while maintaining full blending capability when needed.
