Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If physical power transfer components (such as slip rings) are used between stationary base and rotating base, then electric power can be transferred, but the rotating base becomes heavier and more complex with increased friction and durability issues
Solution Approach 1:
The patent replaces the mechanical power transfer system (slip rings and brushes) with an electromagnetic induction system. The transmitting coil in the stationary base and receiving coil in the rotating base enable wireless power transfer through electromagnetic coupling, eliminating the need for physical contact components and thereby reducing the weight and complexity of the rotating base.
Solution Approach 2:
The patent introduces electromagnetic fields as an intermediary medium to transfer power between the stationary and rotating bases. The transmitting coil generates an electromagnetic field that couples with the receiving coil, enabling power transfer without direct mechanical connection, thus avoiding the friction and wear associated with traditional slip ring mechanisms.
2Use of energy by moving object
If physical power transfer components are used between stationary base and rotating base, then electric power can be transferred, but the device complexity increases and durability decreases
Solution Approach 1:
The patent replaces the mechanical power transfer system (slip rings and brushes) with an electromagnetic induction system. The transmitting coil in the stationary base and receiving coil in the rotating base enable wireless power transfer through electromagnetic coupling, eliminating the need for physical contact components and thereby reducing the weight and complexity of the rotating base.
3Use of energy by moving object
If physical power transfer components are used between stationary base and rotating base, then electric power can be transferred, but friction increases and durability decreases
Solution Approach 1:
The patent replaces the mechanical power transfer system (slip rings and brushes) with an electromagnetic induction system. The transmitting coil in the stationary base and receiving coil in the rotating base enable wireless power transfer through electromagnetic coupling, eliminating the need for physical contact components and thereby reducing the weight and complexity of the rotating base.
4Measurement precision
If traditional distance measurement methods (ruler or triangulation) are used, then distance can be measured, but accuracy decreases and multiple operators are required for long distances
Solution Approach 1:
The patent employs optical energy (laser) instead of mechanical measurement tools. The laser emits a beam that reflects off the target object, and the optical sensor detects the reflected light to calculate distance, eliminating the need for manual ruler measurements or triangulation setups and significantly improving both accuracy and ease of operation.
Solution Approach 2:
The patent utilizes the periodic rotation of the rotating base to sweep the laser beam across the measurement area. This periodic scanning action allows the system to cover a wide field of view and measure multiple points sequentially, improving operational efficiency and accuracy without requiring multiple operators.
