Terminal Device Height Calibration for Equipment Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of selecting and controlling multiple pieces of equipment with a single remote controller increases, leading to usability issues due to the need for precise position, direction, and altitude information, which existing technologies do not adequately address.
Innovation Solution
A terminal device equipped with position, height, direction, and tilt detection units, along with memory storage for equipment information, allows for simplified operation by calculating and calibrating height information to narrow down and control specific equipment within a predetermined view angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If altitude information is added to improve equipment selection accuracy, then usability is improved, but calibration complexity increases
Solution Approach 1:
The system performs automatic calibration using the relationship between position information and altitude information without requiring manual calibration operations. The calibration is executed autonomously by the control unit, eliminating the need for user intervention in the calibration process.
Solution Approach 2:
The calibration process is performed in advance before actual equipment control operations. By pre-calibrating the altitude information using position data and stored equipment information, the system ensures accurate equipment selection is ready before use, avoiding complex calibration procedures during operation.
2Measurement precision
If multiple position and direction parameters are collected to narrow down equipment, then control precision is improved, but operation complexity increases
Solution Approach 1:
The terminal device automatically acquires and processes position information, direction information, and altitude information without requiring manual input from the user. The control unit autonomously performs the complex calculations to determine the view angle and identify equipment, making the operation simple for the user while maintaining high precision.
Solution Approach 2:
The system replaces manual equipment selection mechanisms with automated computational methods. Instead of requiring users to manually navigate complex selection interfaces, the system uses mathematical calculations based on position and direction data to automatically identify and present relevant equipment.
