Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a push rod and press detection part are used to detect lid closure, then lid closure detection is achieved, but the device becomes complex and prone to contamination
Solution Approach 1:
The patent replaces the mechanical push rod and press detection part with an electromagnetic sensing system. The electromagnetic sensor detects the position of the lid without physical contact, eliminating the need for mechanical components that can become contaminated or complex. This substitution maintains detection reliability while simplifying the overall device structure.
Solution Approach 2:
The patent introduces an electromagnetic field as an intermediary between the lid and the detection system. Instead of direct mechanical contact, the electromagnetic sensor detects changes in the electromagnetic field caused by the lid's position, providing a non-contact detection method that avoids contamination and mechanical complexity.
2Measurement precision
If wireless communication module is used for lid detection, then detection accuracy improves, but power consumption increases
Solution Approach 1:
The patent employs periodic electromagnetic sensing at specific intervals rather than continuous wireless communication. The system activates the electromagnetic sensor only when needed to detect lid position changes, reducing overall power consumption while maintaining detection precision. This periodic action replaces the continuous operation of wireless communication modules.
3Shape
If transparent container body is used, then design aesthetics improve, but structural integrity may be compromised
Solution Approach 1:
The patent utilizes composite material construction for the container body, combining transparent materials with reinforcing elements. This allows the container to maintain its aesthetic transparency while incorporating structural reinforcements that enhance strength and durability. The composite approach resolves the conflict between visual appeal and structural integrity.

Data Source
AI summary
Proposed is a blender, in which a blender body operates when closure of the container lid on a container body is detected. In the blender, when the closure of the container lid is detected, power is transmitted from a first inductive coil of the blender body to a second inductive coil of the container body. A transmission module of the container body transmits a signal to a receiving module of the blender body by suing the power transmitted to the second inductive coil. When the signal is received by the receiving module, the blender body detects the closure of the container lid and is operated.
