Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surveying devices lack ease of use, particularly in fine-tuning the orientation of the sighting unit, due to a lack of scalability in the sensitivity of remote control units, making precise alignment challenging.
Innovation Solution
A surveying device equipped with a hand-held remote control unit featuring inertial sensors, goniometers, and adjustable sensitivity settings, allowing for dynamic and scalable control of the sighting unit's orientation, enabling both coarse and fine adjustments with high accuracy and speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a remote control unit with fixed sensitivity is used to control the sighting unit, then the device is simple to operate for coarse alignment, but it becomes difficult to achieve fine-tuning precision
Solution Approach 1:
The remote control unit's sensitivity is made dynamically adjustable through multiple sensitivity levels. The control unit can switch between different sensitivity modes (e.g., low sensitivity for coarse alignment, high sensitivity for fine-tuning), allowing the operator to adapt the control characteristics to the current operational requirement. This dynamic adjustment resolves the contradiction by providing both ease of operation for initial alignment and measurement precision for fine-tuning.
Solution Approach 2:
The sensitivity parameter of the remote control unit is made variable rather than fixed. By changing the sensitivity parameter between different operational phases (coarse alignment vs. fine-tuning), the system achieves both operational ease and measurement precision. The control unit responds to operator input with different gain levels, enabling the same device to serve both purposes effectively.
2Device complexity
If manual adjustment screws are used to change the sighting direction, then the device structure is simple, but the alignment speed and efficiency are low
Solution Approach 1:
The manual mechanical adjustment screws are replaced with an automated motorized drive system controlled by the remote control unit. The motorized drive electronically adjusts the sighting unit's orientation based on operator input or automated calculations, dramatically increasing alignment speed while maintaining acceptable structural complexity through the use of standard motorized components.
Solution Approach 2:
The system incorporates automated calculation and control capabilities that can independently determine the required sighting direction adjustments. The evaluation unit calculates optimal alignment parameters and automatically controls the motorized drive, reducing the need for manual intervention and significantly improving alignment speed and efficiency.
3Length of stationary object
If a telescopic sight is used to observe distant points, then the measurement range is extended, but the device complexity and setup time increase
Solution Approach 1:
The imaging detector is designed to serve multiple functions: it acts as both a telescopic sight for visual observation of distant points and as a sensor for automated coordinate measurement. This multi-functionality extends the measurement range while avoiding the need for separate telescopic equipment, thereby reducing overall device complexity and setup time.
Solution Approach 2:
The optical telescopic sight is supplemented or replaced by an electronic imaging system with digital zoom and image processing capabilities. This electronic approach extends the effective measurement range without the mechanical complexity of long-focus optical systems, and integrates seamlessly with the automated measurement functions of the surveying device.
