Adjustable Prism Corner Stand for Surveying Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional prism poles face inaccuracies when measuring corners, especially chamfered or beveled corners, and angled shots, due to the need for manual positioning and compensation for non-standard angles, leading to measurement inaccuracies.
Innovation Solution
An adjustable prism corner stand that allows for translational and rotational adjustments to accurately position a prism relative to a distance measuring device, enabling precise measurements by fitting over or inside corners and compensating for angle discrepancies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a round pole is used for corner measurements, then the pole can be easily manufactured and handled, but the surveyor must manually position the pole which causes measurement inaccuracies
Solution Approach 1:
The prism support is made adjustable relative to the pole, allowing it to be positioned at different locations along the pole length. This dynamic positioning capability enables the prism to be placed at the optimal location for accurate corner measurements while keeping the pole structure simple and easy to manufacture.
Solution Approach 2:
The pole is divided into multiple sections that can be adjusted relative to each other, and the prism support is segmented as a separate adjustable component. This segmentation allows independent optimization of the pole structure for ease of manufacture while the adjustable support provides the precision positioning needed for accurate measurements.
2Device complexity
If the surveyor manually positions the pole at the corner, then the equipment remains simple, but inaccuracies occur where the pole is not accurately located
Solution Approach 1:
The prism support transitions from a fixed to an adjustable position relative to the pole, enabling dynamic positioning that adapts to different measurement scenarios. This provides accurate pole positioning without requiring complex automated positioning systems, maintaining simplicity while improving precision.
3Device complexity
If the prism position is fixed on the pole, then the structure remains simple, but the prism cannot be accurately positioned relative to a spaced apart measuring device
Solution Approach 1:
The prism support is designed with adjustable positioning mechanisms that allow the prism to be moved to different locations along the pole. This dynamic adjustment capability enables accurate positioning relative to spaced apart measuring devices while keeping the adjustment mechanism relatively simple through the use of sliding or telescoping components.
Solution Approach 2:
The pole structure is segmented into adjustable sections with the prism support as a separate movable component. This segmentation allows the prism to be independently positioned at various locations without complicating the overall structure, as each segment can be adjusted independently to achieve the desired precision.
