Solution Overview
Problem
Existing blenders face issues with detecting the closure of the container lid due to contamination, design limitations, and the need for additional components like wireless communication modules or coils, which complicate the detection process and require high power transmission, while also spoiling the transparent design of the container body.
Innovation Solution
A blender that detects the closure of the container lid through current transmission between conductor sets on the main body and container body, using metal conductors or conductivity rubbers, with a detection module and transparent electrode film to maintain design integrity and allow for easy attachment and detachment.
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 the press detection part may be contaminated by moisture or food
Solution Approach 1:
The patent merges the container lid structure with the detection functionality by integrating a conductive member directly into the lid. This eliminates the need for separate push rods and press detection parts, reducing device complexity while maintaining reliable closure detection through electrical contact between the conductive member and contact electrode.
Solution Approach 2:
The patent introduces a conductive member as an intermediary element that bridges the container lid and the main body's contact electrode. This intermediary enables reliable electrical signal transmission for closure detection without requiring complex mechanical press detection mechanisms, thereby reducing overall system complexity.
2Reliability
If a push rod is installed along the container body in longitudinal direction, then the closure detection is achieved, but the design of transparent container body is spoiled
Solution Approach 1:
The patent replaces the mechanical push rod system with an electrical detection system using a conductive member and contact electrode. This substitution eliminates the need for visible mechanical components along the container body's longitudinal direction, preserving the transparent container's aesthetic appearance while maintaining reliable closure detection functionality.
3Reliability
If wireless communication module is used to detect container lid closure, then the detection function is achieved, but additional power supply is required in the container body
Solution Approach 1:
The patent implements a passive detection system where the conductive member in the container lid serves its own detection function without requiring additional power supplies. The system utilizes the existing electrical connection between the conductive member and contact electrode to detect closure status, eliminating the need for powered wireless communication modules in the container body.
4Reliability
If two coils are installed in main body and container body for electromagnetic detection, then the closure detection is achieved, but the device complexity increases and high power is required for transmission
Solution Approach 1:
The patent extracts and eliminates the complex two-coil electromagnetic system from the detection mechanism. Instead, it uses a simplified electrical contact system with a conductive member and contact electrode, removing the unnecessary coils and power transmission requirements while maintaining reliable closure detection functionality.
5Reliability
If conductor sets are fixedly installed in main body and container body, then the closure detection is reliable, but the ease of manufacture and assembly decreases
Solution Approach 1:
The patent implements a dynamic, removable conductor configuration that allows the container body to be easily assembled and disassembled. The conductive member and contact electrode can be connected or disconnected as needed, providing both reliable closure detection when connected and ease of manufacturing and assembly through simple attachment mechanisms.

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, current is transmitted from a first conductor set of the main body to a second conductor set of the container body, and when the current transmitted through the second conductor set is detected, the main body recognizes the closure of the container lid of the container body and operates.
