Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a belt and bearing system is used to rotate the distance measuring unit, then the motor can be mounted on the outside, but the structure becomes complex and durability decreases
Solution Approach 1:
The patent extracts and removes the belt and bearing components from the system. The distance measuring unit is directly coupled to the motor shaft, eliminating the intermediate transmission elements (belt and bearing) that caused structural complexity and reliability issues. This direct coupling approach simplifies the structure while improving durability by removing friction and wear-prone components.
Solution Approach 2:
The patent replaces the mechanical belt-bearing transmission system with a direct mechanical coupling to the motor shaft. This substitution eliminates the need for intermediate mechanical transmission elements, reducing structural complexity and improving reliability by removing components subject to friction, wear, and potential failure.
2Object-generated harmful factors
If a belt and bearing system is used for rotation, then motor mounting is enabled, but noise increases and lifespan is reduced
Solution Approach 1:
The patent extracts and removes the noise-generating belt and bearing components from the system. By directly coupling the distance measuring unit to the motor shaft, the invention eliminates the mechanical friction and vibration sources that produce noise, while simultaneously removing the wear-prone components that limit the system's operational lifespan.
Solution Approach 2:
The patent replaces the noisy and wear-prone mechanical belt-bearing transmission system with a direct coupling to the motor shaft. This substitution eliminates the intermediate mechanical elements that generate noise through friction and vibration, while also removing the components subject to wear that limit the system's operational life.
3Adaptability or versatility
If the distance measuring unit rotates with the motor, then 360-degree measurement is achieved, but power and signal transmission becomes complex
Solution Approach 1:
The patent implements a rotary transformer that simultaneously handles both power transmission and signal transmission through a single integrated structure. The transformer couples the rotating distance measuring unit with the stationary control circuit, enabling both electrical power delivery and bidirectional signal communication (distance data from sensor, control signals to sensor) through the same rotational interface, thus achieving multi-functionality.
Solution Approach 2:
The rotary transformer acts as an intermediary device between the rotating distance measuring unit and the stationary control circuit. It mediates the transmission of both power and signals across the rotational interface, converting rotational motion into electrical coupling that enables continuous power supply and bidirectional data communication without requiring complex sliding contacts or rotary joints.
