Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a signal source marker or sensor is fixed at the mechanical arm end, then the mechanical arm can perform operations in three-dimensional space, but the marker or sensor becomes delicate and fixed, making it difficult to modify or replace
Solution Approach 1:
The patent uses a heat source as a virtual copy替代 the physical signal source marker or sensor. The heat source emits thermal signals that are detected by infrared cameras, creating a virtual representation of the mechanical arm's position and orientation. This allows the system to maintain positioning accuracy while enabling easy modification or replacement of the heat source without affecting the underlying mechanical structure.
Solution Approach 2:
The patent replaces the mechanical signal source marker or sensor system with a thermal field-based detection system. Instead of using physical markers that require mechanical attachment and are difficult to modify, the system uses a heat source that emits thermal energy detectable by infrared cameras, eliminating the need for delicate mechanical components at the arm end.
2Measurement precision
If a heat source is used at the mechanical arm proximal end with gyroscope data, then accurate tracking and calibration of the mechanical arm's distal end is achieved, but the system complexity increases
Solution Approach 1:
The patent introduces a heat source as an intermediary between the mechanical arm and the detection system. The heat source converts the mechanical arm's position and orientation information into thermal signals, which are then detected by infrared cameras. This intermediary enables accurate tracking of the mechanical arm's distal end by providing a detectable signal that reflects the arm's configuration without requiring direct attachment of sensors at the distal end.
Solution Approach 2:
The heat source serves multiple functions: it acts as a signal source for infrared detection, provides thermal contrast for visualization, and enables tracking of both position and orientation when combined with gyroscope data. This multi-functionality reduces the need for separate components, thereby managing system complexity while achieving high measurement precision.

AI summary
A gyroscope-based system and method is disclosed. Image information data is collected; a mechanical arm working environment image is modeled; a heat source supply apparatus and a gyroscope are provided at the mechanical arm proximal end; the position of the proximal end is accurately measured by accurately tracking the heat source at the proximal end; the relative position of the mechanical arm distal end is accurately calculated by using high-precision angle information measured by the high-precision gyroscope in combination with a number-theoretic formula. The disclosure provides separately determining the position of the distal end, or for assisting other algorithms or apparatuses that track the position of the mechanical arm distal end in error correction and calibration of the position of the mechanical arm distal end. The position of the mechanical arm distal end can be continuously and dynamically tracked in real time, and virtualized in the corresponding image system.
