Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As-built surveys face challenges in achieving accurate measurements due to difficulties in locating the center of anchor bolts and maintaining the survey pole's position, leading to potential inaccuracies in dimensional measurements.
Innovation Solution
A survey tool featuring a conical receiver with a narrow and wide end for centering on stationary fasteners, coupled with a connector and a rod equipped with a level for improved accuracy and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a steel point footer is used to locate the survey pole on the surface, then the pole can be positioned on various surface conditions, but it becomes difficult to accurately locate and maintain the center of the anchor bolt during measurements
Solution Approach 1:
The survey pole is divided into separate functional components: a footer for surface adaptation and a conical receiver for precise bolt centering. This segmentation allows each component to optimize its specific function without compromising the other.
Solution Approach 2:
The conical receiver acts as an intermediary between the survey pole and the anchor bolt. Its tapered geometry provides a self-centering mechanism that mediates the positioning challenge, automatically aligning the pole with the bolt center regardless of initial placement variations.
2Stability of the object's composition
If a T-shaped steel footer is used to increase contact area and avoid deformation, then the footer can distribute load on soft surfaces, but it still cannot ensure accurate centering on the anchor bolt
Solution Approach 1:
The footer and centering mechanism are separated into distinct components. The T-shaped footer provides stable surface contact while the conical receiver handles the centering function, allowing each to be optimized for its specific purpose.
Solution Approach 2:
The conical receiver uses a curved, tapered surface geometry to achieve self-centering. The conical shape guides the positioning process, naturally directing the pole to the center of the anchor bolt through its geometric properties rather than requiring precise manual alignment.
3Device complexity
If manual centering of the survey pole on the anchor bolt is attempted, then the equipment remains simple, but accuracy is compromised due to difficulty in locating and maintaining the center position
Solution Approach 1:
The conical receiver enables the survey pole to self-center on the anchor bolt through its geometric design. The tapered cones automatically guide the pole to the correct position without requiring the operator to manually calculate or precisely locate the bolt center, making the system self-aligning.
Solution Approach 2:
The conical receiver is pre-positioned on the anchor bolt before the survey pole is attached. This preliminary placement establishes the correct centering geometry in advance, so that when the pole is attached, it is already properly aligned with the bolt center.
