Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If infrared technology is used for remote control, then the control system is simple and cost-effective, but the communication distance is limited to not more than 50 meters
Solution Approach 1:
The patent introduces repeaters as intermediary devices to extend the communication distance. The repeaters receive wireless signals from the first repeater and forward them to the rotary laser, acting as mediators that amplify and relay the control signals over longer distances without requiring a complete system redesign
Solution Approach 2:
The control system is segmented into multiple functional modules: a communication terminal with a first repeater, additional repeaters positioned along the transmission path, and the rotary laser with a second repeater. This segmentation allows the system to achieve extended communication distance through distributed signal relay while maintaining modular simplicity
2Ease of operation
If a dedicated remote control device is used, then the control function is dedicated and reliable, but the system cost increases and portability decreases
Solution Approach 1:
The patent makes the mobile communication terminal universal by enabling it to serve dual purposes: its original communication functions plus serving as the control terminal for the rotary laser. The first repeater integrated into the mobile terminal allows it to relay control signals, eliminating the need for a dedicated remote control device and enhancing portability
Solution Approach 2:
The control function is merged with the mobile communication terminal by integrating the first repeater into it. This combination consolidates multiple functions (communication and control relay) into a single portable device, reducing system complexity and eliminating the need for separate dedicated control hardware
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively increases the communication distance for remote control and monitoring of rotary lasers, enhancing operational flexibility and reducing costs by utilizing a portable mobile communication terminal for control operations.
Implementation Method 1

Data Source
AI summary
A control system for a rotary laser receives control information transmitted by a communications terminal via a first repeater coupled to the communications terminal and transmits the control information to a controller via a second repeater disposed on a rotary laser. The controller regulates an operating state of the rotary laser based on the control information. The control system enables the communication terminal to wirelessly control and operating state of the rotary laser via cooperation between the first repeater and the second repeater so as to achieve a remote control and to avoid use of a dedicated remote control alone, reduce the system costs and be carried easily.
