Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the power signal line is exposed on the outer surface of the telescopic mast, then it is easy to connect and access, but the power signal line is damaged due to external environment exposure leading to poor insulation and disconnection
Solution Approach 1:
The power signal line is embedded within the hollow cavity of the telescopic mast structure, nesting the electrical conductor inside the protective tubular body. This nesting arrangement protects the power signal line from external environmental damage while maintaining a compact integrated design.
Solution Approach 2:
The telescopic mast acts as a flexible protective shell that encloses the power signal line within its hollow cavity. This shell structure provides mechanical protection and environmental isolation while allowing the power signal line to function reliably throughout the telescopic range.
2Reliability
If the power signal line is installed inside the cavity of the telescopic mast, then the power signal line is protected from external damage, but the connection complexity increases
Solution Approach 1:
The telescopic mast structure serves multiple functions simultaneously: it provides the structural support for telescopic movement, contains the hollow cavity for power signal line routing, and acts as the protective enclosure. This multi-functionality reduces overall connection complexity despite the embedded wiring arrangement.
3Ease of operation
If a user manually adjusts the entire height of the telescopic mast by seeing a numerical figure displayed in a section with naked eyes, then the user can control the height, but accuracy and stability are lowered
Solution Approach 1:
The patent replaces manual visual estimation with an automated sensor-based measurement system. Optical or electronic sensors detect the actual height of the telescopic mast and provide feedback to the control system, enabling precise height positioning without relying on manual visual judgment by the user.
Solution Approach 2:
The control system receives real-time feedback from sensors about the actual telescopic mast height and compares it with the target height. Based on this feedback, the control system automatically adjusts the telescopic sections to achieve the desired precision, eliminating the need for manual visual measurement and improving both accuracy and stability.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The embedded power signal line prevents damage from the external environment, and the magnetic switch ensures precise control of the mast's length, enhancing durability, stability, and ease of operation.
Implementation Method 1
a magnetic switch electrically connected to the power signal line, and the tubular section adjacent to the tubular main body may further include a guide unit corresponding to a position of the magnetic switch and parallel in the length direction on an outer surface, and a magnetic body disposed at a point of the guide unit to generate a magnetic field for driving the magnetic switch
