Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If laser range finder integrates all functions and interfaces in one device, then functionality is improved, but device complexity and size increase
Solution Approach 1:
The system divides functionality between two devices: a simplified measuring device (laser range finder) and a smart terminal (mobile device). The measuring device handles only measurement tasks while the smart terminal provides the complex interface, display, and additional processing capabilities. This segmentation resolves the contradiction by distributing complexity to where it is most needed while keeping the measuring device simple and compact.
Solution Approach 2:
The patent introduces a wireless communication connection as an intermediary between the measuring device and smart terminal. This intermediary enables the measuring device to offload complex operations to the smart terminal without requiring direct physical integration. The wireless connection allows the measuring device to maintain simplicity while still accessing the full functionality of the smart terminal's processor, display, and user interface.
2Ease of operation
If laser range finder includes display and control keys, then ease of operation is improved, but device size and complexity increase
Solution Approach 1:
The patent extracts the display and control interface functions from the measuring device and relocates them to the smart terminal. The measuring device retains only the essential measurement functionality, while the smart terminal provides the comprehensive display, buttons, and user interface. This extraction resolves the contradiction by removing bulky components from the measuring device while preserving ease of operation through the smart terminal's interface.
Solution Approach 2:
The smart terminal serves multiple functions: it acts as the display device, control interface, data processing unit, and storage system for the measuring device. By making the smart terminal universal and multi-functional, the patent eliminates the need for the measuring device to include separate display and control components, thereby reducing its size while maintaining ease of operation through the smart terminal's capabilities.
3Speed
If measurement results are processed locally in measuring device, then processing speed is improved, but device complexity and power consumption increase
Solution Approach 1:
The wireless communication connection serves as an intermediary for data transfer between the measuring device and smart terminal. Instead of processing all data locally in the measuring device, the system uses the intermediary connection to rapidly transfer measurement data to the smart terminal for processing. This approach maintains processing speed by leveraging the smart terminal's superior processing power while reducing the measuring device's power consumption and complexity.
Solution Approach 2:
The patent replaces the mechanical approach of local processing in the measuring device with an electronic/digital approach using wireless communication and remote processing via the smart terminal. This substitution allows the system to leverage the smart terminal's processing capabilities without requiring the measuring device to have equivalent processing power, thereby reducing its power consumption and complexity while maintaining overall system processing speed.
