Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage mixing systems face challenges in consistently achieving the right viscosity for frozen beverages, often resulting in products that are too thick for conventional drinking straws, and inefficiencies in mixing time due to reliance on nichrome heating elements and moving parts.
Innovation Solution
The system employs inductive coupling to heat the mixing blade, combined with optical heating using LEDs, to efficiently transfer heat directly to the beverage slurry, minimizing energy loss and avoiding damage to motor components, while using a ferromagnetic mixing blade to optimize heat distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If nichrome heating elements are used to heat the beverage mixture, then heating function is provided, but energy loss increases and motor components overheat
Solution Approach 1:
The patent replaces the traditional nichrome heating element with an induction heating system that uses electromagnetic fields to directly heat the beverage mixture through a ferromagnetic stirring blade. This substitution eliminates the need for direct contact heating elements that cause energy loss and motor overheating, as the heating occurs through electromagnetic induction in the ferromagnetic material of the blade itself.
Solution Approach 2:
The ferromagnetic stirring blade serves as an intermediary between the induction heating source and the beverage mixture. The blade absorbs electromagnetic energy through induction and transfers it to the mixture through direct contact during stirring, efficiently heating the beverage without requiring separate heating elements that cause energy loss.
2Productivity
If traditional mixing systems are used, then mixing function is provided, but mixing time increases due to inefficiency
Solution Approach 1:
The patent merges the stirring function and heating function into a single integrated operation. The ferromagnetic stirring blade simultaneously performs mechanical mixing and absorbs induction heat to warm the beverage mixture, eliminating the need for separate heating and mixing steps. This combination significantly reduces total preparation time while maintaining mixing effectiveness.
Solution Approach 2:
The induction heating operates continuously during the entire stirring process, ensuring that heat is applied throughout the mixing duration. This continuous heating action, combined with constant stirring, maintains optimal temperature and viscosity throughout the beverage mixture, reducing the time needed to achieve desired consistency compared to intermittent or separate heating methods.
3Manufacturing precision
If heating is applied to achieve desired viscosity, then beverage consistency improves, but motor components may overheat
Solution Approach 1:
The patent extracts the heating function from the motor assembly by using induction heating through the ferromagnetic blade. This separation prevents heat from being transferred to motor components, as the electromagnetic heating occurs in the blade itself rather than in the motor housing or windings. The motor only provides mechanical rotation without being exposed to thermal stress.
Solution Approach 2:
The patent replaces traditional contact-based heating with induction heating, which uses electromagnetic fields to heat the ferromagnetic blade without physical contact. This substitution eliminates the thermal pathway that would otherwise transfer heat to motor components, protecting them from overheating while achieving precise beverage viscosity control through controlled induction heating.
