Solution Overview
Problem
Existing blenders face challenges in accurately detecting the closure of the container lid without contamination or design compromise, particularly with transparent containers, and require complex setups with multiple coils and power supplies.
Innovation Solution
A blender design utilizing a single induction coil in the main body and another in the container body, achieving detection through one-time inductive coupling, which prevents contamination, maintains the transparent design, and operates with low power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a push rod and press detection part are used to detect container lid closure, then the closure detection function is achieved, but the device complexity increases and contamination risk arises
Solution Approach 1:
The patent extracts the detection function from mechanical components (push rod and press detection part) and relocates it to the container lid itself through a detection hole. This eliminates the need for separate detection components in the main body, reducing device complexity while maintaining detection reliability.
Solution Approach 2:
The detection hole in the container lid serves as an intermediary element that enables the main body to detect lid closure without direct mechanical contact. The hole acts as a mediator that transmits the closure state information from the lid to the sensor in the main body, simplifying the overall detection mechanism.
2Reliability
If a push rod is installed along the container body in longitudinal direction, then closure detection is achieved, but the transparent design of the container body is spoiled
Solution Approach 1:
The patent removes the visual obstruction (detection components) from the container body structure and places the detection functionality in the lid. This extraction allows the container body to maintain its transparent appearance without compromising closure detection capability.
Solution Approach 2:
The detection hole is created locally in the container lid rather than requiring longitudinal installation through the entire container body. This localized approach preserves the transparent quality of the container body while achieving detection functionality where needed.
3Reliability
If multiple coils are installed in main body and container body for electromagnetic detection, then closure detection is achieved, but the device complexity and power requirements increase
Solution Approach 1:
The patent extracts the electromagnetic detection requirement from the container body and concentrates it in the main body only. By placing a single coil in the main body and using the detection hole in the lid, the system eliminates the need for multiple coils and complex bidirectional electromagnetic coupling, thereby reducing power consumption.
Solution Approach 2:
The single coil in the main body serves multiple functions: it generates the electromagnetic field for detection and works with the detection hole in the lid to achieve closure detection. This multi-functional approach eliminates the need for separate coils in both the main body and container body, reducing overall power requirements.

AI summary
Proposed is a blender in which when the closure of a container lid of a container body is detected, a main body operates. In the blender, when the closure of the container lid of the container body is detected, power is transmitted from a first induction coil of the main body to a second induction coil of the container body, and by using the power transmitted to the second induction coil, an electromagnet module of the container body transmits a signal to a receiving module of the main body, and when the receiving module receives the signal, the main body recognizes the closure of the container lid of the container body and operates.
