Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional measuring instruments for irregular objects are cumbersome, prone to measurement errors due to offset issues, and require multiple rulers or replacements, making them difficult to use and store.
Innovation Solution
An intelligent electronic measuring instrument with a first fixing seat, mounting flanges, a shaft sleeve, main board, angle sensor, and swivel mechanism, featuring multiple shaft sleeves for stable and accurate length measurement, with a display screen for intuitive output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a measuring ruler is used to wrap around irregular objects, then the measurement can be performed, but the starting point is prone to offset resulting in measurement errors and the operation becomes troublesome
Solution Approach 1:
The patent replaces the traditional mechanical measuring ruler with an electronic measuring instrument that uses electronic components (angle sensor, gear, shaft sleeve) to automatically measure and calculate the length of irregular objects, eliminating manual wrapping and starting point alignment issues
Solution Approach 2:
The measuring instrument automatically performs measurement and calculation functions without requiring user intervention for starting point alignment or multiple markings, with the electronic system self-correcting and computing the final length directly
2Adaptability or versatility
If the measurement range exceeds the length of the ruler, then multiple markings or ruler replacements are needed, but this increases operation complexity and storage difficulty
Solution Approach 1:
The electronic measuring instrument is designed with a universal measurement capability that can handle various measurement ranges through electronic scaling and calculation, eliminating the need for multiple physical rulers or marking operations
Solution Approach 2:
The instrument features a rotatable shaft sleeve mechanism that can dynamically adjust to different measurement scenarios, with the angle sensor and gear system adapting the measurement scale electronically rather than requiring physical ruler changes
