Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mechanical push rod or link is used to detect container lid closure, then the detection function can be achieved, but the device complexity increases and manufacturing becomes difficult
Solution Approach 1:
The patent replaces the mechanical push rod or link system with an electromagnetic detection system. A coil is positioned to detect the presence of a magnetic component on the container lid through electromagnetic induction, eliminating the need for mechanical moving parts while achieving reliable detection of lid closure status.
Solution Approach 2:
The patent introduces a magnetic component as an intermediary element. The magnetic component is attached to the container lid, and the coil detects its presence through electromagnetic fields, serving as a mediator between the lid closure action and the detection system without requiring direct mechanical contact.
2Reliability
If a vertically long push rod or link is installed to transmit detection signal, then the detection function is achieved, but the link may lose detection function due to wear or damage from frequent use
Solution Approach 1:
The patent eliminates the mechanical push rod or link by using electromagnetic detection. The coil generates an electromagnetic field that detects the magnetic component on the lid through non-contact means, removing the mechanical parts that would otherwise wear or break from repeated use.
Solution Approach 2:
The magnetic component serves as an intermediary that carries the detection signal without mechanical contact. It interacts with the coil through electromagnetic fields, allowing the detection function to be transmitted without physical wear or damage to the signal transmission path.
3Reliability
If a push rod and push detection part are installed separately, then the detection function is achieved, but the push detection part may be contaminated by moisture or food
Solution Approach 1:
The patent replaces mechanical detection components that are vulnerable to contamination with an electromagnetic detection system. The coil and magnetic component interact through electromagnetic fields without physical contact, preventing moisture or food from contaminating the detection mechanism.
Solution Approach 2:
The magnetic component acts as a contamination-resistant intermediary. It can be positioned on the lid away from food contact areas and transmits the closure signal through electromagnetic fields to the coil, preventing direct exposure of detection parts to moisture or food contamination.
4Reliability
If mechanical structures are used to transmit signals between container body and main body, then signal transmission is achieved, but the container body design freedom is reduced especially for transparent containers
Solution Approach 1:
The patent replaces visible mechanical signal transmission structures with an electromagnetic detection system. The coil and magnetic component can be positioned within the container body assembly without requiring external mechanical linkages, maintaining signal transmission capability while preserving the aesthetic appearance of transparent container bodies.

AI summary
A blender which an electrical signal via a transparent film so as to detect whether a container lid is closed. The blender includes a container body receiving food; a main body provided under the container body and supporting the container body; a container lid mounted removably to the upper surface of the container body and configured to open/close the upper part of the container body; and a detection system configured to detect whether the container lid is mounted to the container body, wherein the detection system includes a transparent electrode film attached to the surface of the container body and guiding the flow of electricity. Accordingly, the transparent electrode film can transmit whether the container lid is mounted to the main body without spoiling the appearance of the container body made of a transparent material.
