Survey Rod Boot Cantilever Invert Level Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing survey rods are ineffective in accurately measuring the inner diameter of pipes, particularly those recessed within a ground surface or in water, due to difficulty in determining the invert level, leading to measurement errors and inability to measure outer diameters.
Innovation Solution
A survey rod boot assembly with a deformably resilient rod support body, cantilever members, and ribs that securely attach to the survey rod, allowing for precise measurement of pipe dimensions by resting on the pipe's internal surface, enabling accurate invert level determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional survey rod is used to measure pipe dimensions, then the rod can be inserted into the pipe, but the user cannot accurately determine when the distal end has reached the bottom inner surface (invert level), resulting in measurement errors
Solution Approach 1:
The patent introduces an intermediary component (the boot assembly with cantilever members) that mediates between the survey rod and the pipe invert surface. The cantilever members extend beyond the rod's distal end and make contact with the invert level, providing a visual indicator when the rod has reached the correct depth, thus solving the problem of determining invert level accurately
Solution Approach 2:
The patent utilizes visual indicators (color changes or visual markings) on the cantilever members or boot assembly to indicate when the distal end of the survey rod has reached the invert level. This allows the user to easily determine the correct measurement depth through visual observation rather than tactile feedback alone
2Adaptability or versatility
If a conventional survey rod is used, then the rod structure is simple, but the user is prevented from utilizing the rod for its conventional purpose and measuring outer diameter of pipes
Solution Approach 1:
The patent segments the measurement device into distinct functional components: the survey rod itself and the boot assembly with cantilever members. This segmentation allows the rod to maintain its conventional simplicity while the boot assembly provides additional functionality for measuring both inner and outer pipe dimensions, thereby increasing adaptability without significantly complicating the core rod structure
Solution Approach 2:
The boot assembly with cantilever members is designed to provide multiple functions: it enables measurement of the invert level (inner dimension), allows measurement of outer pipe diameter, and maintains compatibility with conventional survey rods. This multi-functionality increases the adaptability of the overall measurement system
3Measurement precision
If the survey rod distal end is inserted deep into recessed pipes or water bodies, then measurements can be obtained, but the operation becomes unsafe and inefficient
Solution Approach 1:
The boot assembly acts as an intermediary that extends the measurement capability beyond the rod's distal end. The cantilever members reach the invert level while the user can observe the measurement from a safer distance, eliminating the need for the user to manually insert the rod deep into hazardous environments while maintaining measurement accuracy

AI summary
A survey rod boot utilized with a survey rod, wherein the survey rod includes a rod support body defining a receiving aperture disposed on an upper surface of the rod support body, defining, with an enclosed inner sidewall of the rod support body, a receiving channel spanning from the receiving aperture into the rod support body, wherein the survey rod is disposed therein and frictionally retained by, and selectively, removably, and directly coupled to, the enclosed inner sidewall of the rod support body. The boot also has at least one cantilever member projecting in a direction outwardly from a sidewall of the rod support body and has a lower surface opposing an upper surface of the at least one cantilever member and defining a body resting plane so a user can obtain a measurement from the survey rod boot.
