Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the container cup is not securely locked, then the structure is simple and easy to install, but the container cup shakes and separates from the main body during high-speed stirring
Solution Approach 1:
The locking mechanism is divided into multiple independent locking buckle members (at least three) distributed around the container cup assembly. Each locking buckle member independently secures the container cup to the mainframe housing, providing redundant fixation points that prevent separation during high-speed stirring while maintaining simple installation through modular design
Solution Approach 2:
The locking buckle members integrate multiple functions: they serve as both the securing mechanism and the structural connection between the container cup assembly and mainframe housing. The locking buckles combine the mounting bracket and fastening elements into a single integrated component that simplifies installation while ensuring reliable fixation
2Device complexity
If photoelectric cover opening protection is used, then the structure is simple, but it has potential danger of instability in poor light conditions
Solution Approach 1:
A micro switch serves as an intermediary mechanical sensor that detects the cover opening state through direct physical contact. The micro switch is actuated by the cover's position, providing a reliable electrical signal that is independent of light conditions. This mechanical intermediary converts the cover's physical state into an electrical control signal for the motor
Solution Approach 2:
The patent replaces the photoelectric detection system with a mechanical detection system using a micro switch. Instead of using light to detect cover position, the system uses direct mechanical contact through the micro switch's actuator arm, which is pushed or pulled by the cover's movement to open or close the electrical circuit, eliminating dependence on light conditions
3Reliability
If electrical locks with micro switches are used for cover locking, then the cover is securely locked, but the cost is high
Solution Approach 1:
The patent uses inexpensive micro switches and simple mechanical linkages instead of expensive electrical locks. The micro switch is a low-cost component that can be easily replaced if needed, providing reliable cover locking functionality at a fraction of the cost of electronic locking systems while maintaining the same security level
4Device complexity
If the blade holder is not securely fixed, then the assembly is simple, but the blade holder vibrates greatly and may come out during high-speed stirring
Solution Approach 1:
The blade assembly fixing structure uses a locking mechanism that counteracts the centrifugal force and vibration generated during high-speed stirring. The fixing lock engages with the blade holder to provide a counterbalancing mechanical constraint that prevents the blade holder from dislodging, effectively neutralizing the destabilizing forces without adding complex active control systems
5Ease of manufacture
If the motor and blade assembly have eccentricity, then the assembly is easier to manufacture, but it causes large noise and vibration
Solution Approach 1:
Shock-proof pads are installed beforehand at the interface between the motor and the container cup assembly to cushion against eccentricity-induced vibrations. These damping elements are pre-positioned to absorb and dissipate the harmful vibrations and noise generated by motor eccentricity, protecting the overall assembly from excessive mechanical stress and noise without requiring precision manufacturing
6Stability of the object's composition
If the weighing foot assembly is rigidly fixed, then the structure is stable, but it cannot prevent overflow when water is accidentally poured into the mainframe
Solution Approach 1:
The weighing foot assembly is designed with suspended mounting that allows it to move dynamically in response to external forces. The weighing foot can shift position when water is accidentally poured into the mainframe, preventing water accumulation that would lead to overflow. This dynamic adaptability maintains weighing stability during normal operation while providing passive overflow protection during abnormal conditions
