Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional center point locating tools are limited in measuring from irregularly configured objects, markings, and openings, and struggle to accurately locate and mark the center point from various shaped objects, both internally and externally.
Innovation Solution
A center point marking tool device featuring a pair of carriage assemblies with arm shafts, guide holes, and a gear assembly that allows for adjustable positioning and alignment, enabling precise center point location and marking on objects with orthogonal guide holes and post members for versatile use on different shapes and sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional center point locating tools are used, then the tool structure is simple, but the tool cannot accurately locate center points from irregularly shaped objects, markings, or openings
Solution Approach 1:
The device incorporates multiple measurement modes including outside calipers for external measurements, inside calipers for internal measurements, and a scribe point for marking center points on surfaces. This multi-functional design allows the same device to accurately locate center points across various object shapes and configurations, resolving the contradiction between measurement precision and adaptability.
Solution Approach 2:
The caliper arms are designed to be adjustable and movable, allowing the measurement points to be positioned flexibly on irregularly shaped objects. The arms can be extended or repositioned to accommodate different geometries, enabling accurate center point location while maintaining adaptability to various object forms.
2Adaptability or versatility
If conventional center point tools are used, then the device complexity is low, but the tool cannot measure from multiple reference points simultaneously
Solution Approach 1:
The device merges multiple measurement functions into a single integrated tool. The carriage assembly combines outside calipers, inside calipers, and a scribe point on one unified structure, allowing simultaneous or sequential use of multiple reference points without requiring separate tools, thus increasing versatility while controlling overall device complexity.
Solution Approach 2:
The device is segmented into functional modules including the carriage assembly with movable caliper arms and a gear assembly. This modular segmentation allows each component to perform specific measurement tasks while the overall system integrates them for versatile multi-point measurement capability.
3Adaptability or versatility
If adjustable arm shafts are used for extension and contraction, then the device can adapt to various object sizes, but the mechanism complexity increases
Solution Approach 1:
The arm shafts incorporate a telescopic or extendable mechanism that allows dynamic adjustment of the caliper arm length. This dynamic structure enables the device to adapt to various object sizes by extending or contracting the arms as needed, providing size adaptability while using a relatively simple mechanical extension mechanism.

AI summary
The present invention is a tool for locating and marking center points on various objects configured with a geared carriage assembly having guide holes for insertion of posts and a counterpunch centered automatically when posts are inserted into an interior and/or exterior surface of an object such as a square, rectangular, polygon, circle or other circular shapes. The tool is particularly novel to quickly and accurately locate the center point from a hole, aperture, and/or a prick mark made in the surface of the object such as, for example, paper, sheet metal, etc.
