Modular Bore Gage with Universal Set-Master
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bore gages are limited in their ability to accurately measure large and deep bore diameters, as they require multiple tools and lack versatility for varying diameters and depths, and do not provide direct measurement capabilities.
Innovation Solution
A modular large bore gage system combining analog and digital instruments with a retractable centralizer and interchangeable adapters, along with a universal set-master, allows for easy assembly and adjustment to measure a wide range of diameters and extend reachability to deep bores, enabling precise comparison to a known reference dimension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single bore gage is used to measure multiple bore diameters, then versatility is improved, but measurement precision deteriorates due to lack of dedicated reference for each diameter
Solution Approach 1:
The patent implements a universal set-master that can be configured with different master rings corresponding to various bore diameters. This single multi-functional device replaces the need for multiple dedicated bore gages, allowing measurement of different bore sizes while maintaining precision through the use of appropriate master rings for each specific diameter range.
Solution Approach 2:
The set-master is divided into interchangeable master ring components, each calibrated for specific diameter ranges. This segmentation allows the user to select the appropriate master ring for each measurement task, ensuring measurement precision is maintained across different bore diameters while preserving versatility.
2Measurement precision
If multiple dedicated bore gages are used for different diameters, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple dedicated bore gage functions into a single universal set-master device. By integrating multiple master rings and adapters into one system, it reduces the number of separate tools needed while maintaining the measurement precision of dedicated instruments through proper selection of master ring components.
Solution Approach 2:
The universal set-master serves multiple measurement functions that would otherwise require separate dedicated gages. The device can be configured for different bore diameters and depths through interchangeable components, reducing device complexity while preserving measurement accuracy.
3Ease of operation
If standard bore gage reachability is used, then ease of operation is improved, but adaptability to deep bores deteriorates
Solution Approach 1:
The patent employs a telescoping reach rod with adjustable length that can be extended or retracted based on bore depth requirements. This dynamic adjustment capability allows the gage to easily adapt to both shallow and deep bores while maintaining ease of operation through a simple extension mechanism.
Solution Approach 2:
The reach rod is segmented into telescoping sections that can be extended as needed. This segmentation allows the device to maintain a compact form for easy handling while providing extended reach capability for deep bore measurements when required.

AI summary
A large bore measuring system includes a modular and extendable bore gage with analog and digital readouts, also includes a settable set-master. The modular bore gage is designed to measure two sets of large bore diameters. A first set of large bores is accomplished by using a modular bore gage design described in this disclosure. The second set of larger bores is accomplished by adding attachments therein extending the gage for the larger range of bore diameters. A set-master is used for both sets of large bores.
