Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional laser ranging methods are used to measure distance, then measurement capability is provided, but functionality for locating and tracking multiple target objects is lacking
Solution Approach 1:
The ranging device is enhanced with multi-functionality by integrating signal processing capabilities, display units, and processing units that enable the device to perform both traditional laser ranging and new functions such as locating target objects, tracking movement trajectories, and providing real-time feedback. The device can simultaneously measure distance and locate multiple target objects with different types (e.g., partners, hounds, golf holes), making it universally applicable to various outdoor scenarios including hunting and golf.
2Loss of information
If laser beams are emitted to measure distance, then ranging function is achieved, but real-time feedback on target object location and status is not provided
Solution Approach 1:
The invention implements feedback mechanisms by equipping the ranging device with display units that provide real-time visual feedback to users about target object locations, movement trajectories, and status information. The processing unit continuously receives signals from signal modules, calculates positions and distances, and updates the display to show current status of tracked objects, enabling users to monitor and control target objects in real-time during outdoor activities.
3Loss of information
If simple distance measurement is performed, then operation is simple, but comprehensive understanding of application status is limited
Solution Approach 1:
The invention segments the information about target objects into distinct visual elements displayed on the display unit. Different types of target objects (partners, hounds, golf holes) are represented by different icons or visual indicators. The system separately displays location information, movement trajectories, and status information for each tracked object, allowing users to comprehend comprehensive application status through organized, segmented visual feedback without overwhelming operational complexity.
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
Enhances the accuracy of distance measurement by correcting estimated distances and providing real-time tracking and alerts, enabling better control over target objects in outdoor environments.
Implementation Method 1
The most commonly used method at present is the time measurement method, which is to measure the time of laser round trip (Time of Flight, ToF). The principle of ToF is to use an aiming device or a rangefinder to emit coded laser light from a pulsed infrared light source to the target.
Implementation Method 2
the signal processor wirelessly receives the first signal transmitted by the first signal module corresponding to a first target object, wherein the technology for receiving or transmitting the first signal is Bluetooth technology or Wi-Fi technology
Data Source
AI summary
Methods of locating a target object in a ranging device and the ranging devices thereof are provided. First, a signal processor is used to process a first signal of a first signal module corresponding to a first target object, where the first signal at least includes location information. Then, a first target distance corresponding to the first target object is determined based on a device location of the ranging device and the location information in the first signal. After that, a laser ranging unit is used to perform a ranging operation on the first target object to obtain a first laser ranging result, and a display unit is used to display a first icon corresponding to the first target object according to the first target distance or the first laser ranging result.
