Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a scale is provided for manual reading of pole length, then weight and technical simplicity are maintained, but automation and time efficiency are insufficient
Solution Approach 1:
The pole system automatically determines and transmits its own length information through coded identifiers and a reading device, eliminating the need for manual reading while maintaining simplicity. The pole serves itself by encoding length data that can be automatically captured.
Solution Approach 2:
The manual reading process is replaced by an automated optical or magnetic reading system that detects coded identifiers on the pole. This substitution eliminates manual intervention while keeping the pole structure relatively simple.
2Productivity
If a sophisticated measurement system is used for automatic length determination, then automation is achieved, but weight and technical complexity increase significantly
Solution Approach 1:
The complex measurement system is extracted from the pole itself and placed in the surveying instrument. The pole only needs to carry simple coded identifiers, while the reading and processing complexity resides in the instrument.
Solution Approach 2:
Coded identifiers serve as an intermediary between the pole's physical length and the digital measurement system. These codes simplify the interface between the mechanical pole and the electronic measurement instrument.
3Productivity
If a sophisticated measurement system is used for automatic length determination, then automation is provided, but recurring calibrations are required to maintain accuracy
Solution Approach 1:
The coded identifiers are designed as simple, durable markings that do not require calibration. They are essentially permanent features of the pole structure, eliminating the need for recurring calibration procedures.
Solution Approach 2:
The length information is pre-encoded into the pole structure through coded identifiers during manufacturing. This preliminary encoding ensures consistent accuracy without requiring field calibration.
4Device complexity
If manual reading from tape measure is used, then weight and technical simplicity are maintained, but automation and time efficiency are insufficient
Solution Approach 1:
The manual tape measure reading process is replaced by an automated optical or magnetic reading system that quickly detects coded identifiers on the pole, dramatically reducing measurement time while keeping the pole structure simple.
5Adaptability or versatility
If telescopic structure with scale is used, then length adjustability is provided, but manufacturing precision and measurement accuracy deteriorate over time
Solution Approach 1:
The coded identifiers are implemented as durable, precise features during manufacturing that do not wear or drift. They serve as permanent reference markers that maintain accuracy throughout the pole's service life.
Solution Approach 2:
The precise positioning of coded identifiers is established during initial manufacturing with high precision. This preliminary action ensures long-term accuracy without requiring field recalibration.

AI summary
A surveying pole system comprising a surveying pole including two telescopic sections for providing length adjustability. At a first end of the surveying pole, a pointing tip is disposed for positioning on a target point of the environment. At a second end, a length reference point is disposed. The surveying pole also includes a locking mechanism for locking the length adjustability in respective lock-in positions. Each of the lock-in positions provides a corresponding distance between the pointing tip and the length reference point. A plurality of coded identifiers have a predetermined code associated with one of the lock-in positions. The surveying pole also includes a coded-identifier reader for reading the code of a respective coded identifier associated with the respective lock-in position, a communication device configured for transmitting a signal to a surveying instrument, wherein the signal is based at least on the read code.
