Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rechargeable electric stirrers face inconvenience and risk of liquid damage due to the need for frequent cable plugging and unplugging, and existing wireless charging designs may invert the stirrer, risking liquid ingress into the internal circuitry.
Innovation Solution
An electric stirrer and charging base design where the stirrer body is supported on a bearing part, positioning the stirring component below the stirrer body, allowing for convenient charging without liquid exposure and preventing contamination, using conductive parts for electrical connection and a circular charging base structure for stable positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the stirrer body is placed inverted on the charging base for wireless charging, then cable plugging and unplugging is eliminated, but liquid may flow back into the body to damage internal circuitry or motor
Solution Approach 1:
The patent inverts the traditional charging orientation by designing the stirrer to be charged in an inverted position (stirring head facing upward) on the charging base. This inversion allows wireless charging without cable plugging while the liquid-proof cover prevents liquid from flowing into the body, resolving the contradiction between charging convenience and liquid damage protection.
Solution Approach 2:
The patent introduces a liquid-proof cover as an intermediary component between the liquid environment and the internal circuitry/motor. This cover prevents liquid from entering the body during inverted charging, thereby protecting internal components while maintaining the convenience of wireless charging operation.
2Object-affected harmful factors
If the stirring component is covered to prevent contamination, then contamination risk is reduced, but liquid may still enter and damage internal components
Solution Approach 1:
The liquid-proof cover serves as an intermediary protective layer that prevents both contamination of the stirring component and liquid ingress into the internal components. It simultaneously addresses both harmful factors by creating a barrier against external contaminants while preventing liquid from reaching sensitive internal parts.
Solution Approach 2:
The patent segments the protective function into distinct components: the liquid-proof cover protects the stirring component from contamination while the overall inverted positioning and cover design together prevent liquid from reaching internal components. This segmentation allows simultaneous protection against both contamination and liquid damage.
3Ease of operation
If a split inductive charging system is used, then wireless charging is achieved, but the stirrer must be inverted which creates liquid flow risk
Solution Approach 1:
The liquid-proof cover acts as an intermediary barrier that enables the stirrer to be safely inverted for inductive charging. It prevents liquid from flowing into the body during the inverted charging position, thereby allowing wireless charging capability while eliminating the liquid flow risk associated with inverted positioning.
Solution Approach 2:
The patent utilizes inverted positioning as the charging orientation, with the stirring head facing upward on the charging base. This inversion enables split inductive charging functionality while the accompanying liquid-proof cover prevents harmful liquid flow, resolving the contradiction between wireless charging achievement and liquid flow prevention.
