Solution Overview
Problem
Existing systems for length measurement using laser modules and display modules are inefficient, as they often require switching between views, pose eye safety risks from visible laser radiation, and lack user-friendly operation, leading to potential errors and increased costs.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a laser measuring module with visible laser beam is used for length measurement, then the user can easily see the measuring point, but eye safety risks increase due to dangerous laser radiation
Solution Approach 1:
The patent changes the wavelength parameter of the laser from visible spectrum to invisible spectrum (infrared or ultrasonic range). The laser measuring module emits invisible laser beams that are detected by sensors, and the measuring point information is displayed electronically on a display module rather than being visible as light, thus eliminating eye safety risks while maintaining measurement capability
Solution Approach 2:
The patent introduces an intermediary display module that acts as a mediator between the laser measuring module and the user. Instead of directly viewing the laser beam, the user sees electronic display of measuring point information transmitted via communication device, thereby avoiding exposure to dangerous laser radiation
2Ease of operation
If separate laser measuring module and display module are used, then system versatility and ease of operation improve, but device complexity increases
Solution Approach 1:
The patent divides the measurement system into separate functional modules: a laser measuring module for emitting laser beams and detecting measuring points, and a display module for displaying measurement information. These modules can be spatially separated and connected via communication device, allowing flexible operation and positioning while maintaining system functionality
Solution Approach 2:
The display module can be implemented in various forms (head-mounted display, handheld device, fixed display) and the system can operate with different configurations of the modules. The communication device enables universal data transmission between modules, allowing the system to adapt to different operational scenarios and user needs
3Productivity
If real-time data transmission between modules is implemented, then measurement efficiency and productivity improve, but use of energy and device complexity increase
Solution Approach 1:
The communication device transmits position data periodically or at predetermined intervals rather than continuously. The laser measuring module emits laser beams and the display module updates information based on periodic data transmission triggers, reducing energy consumption while maintaining real-time measurement efficiency through timely data updates
