Angled Oral Cavity Measuring Device with Digital Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional oral cavity restoration space measuring devices face challenges in accurately measuring narrow spaces due to vision obscuration and limited flexibility, leading to measurement failures and inaccuracies, especially in the posterior region and lingual side of the anterior region.
Innovation Solution
The device features a shell with a combined transverse and longitudinal section connected at an included angle, allowing for flexible adjustment of the measuring end into the oral cavity and incorporating a digital display meter for precise measurements, eliminating subjective judgment and visual acuity errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional straight measuring device is used, then the device structure is simple, but the measuring end cannot reach narrow oral cavity spaces or be properly observed due to vision obscuration
Solution Approach 1:
The measuring device is divided into multiple sections: a longitudinal section and a transverse section connected at an included angle. This segmentation allows the measuring end to be extended into narrow oral cavity spaces while maintaining structural simplicity through modular design.
Solution Approach 2:
The device transitions from a straight one-dimensional structure to a two-dimensional angular structure by connecting the longitudinal and transverse sections at an included angle. This dimensional change enables the measuring end to access previously unreachable areas of the oral cavity.
2Adaptability or versatility
If the measuring end is extended into narrow oral cavity spaces, then measurement coverage is improved, but reading the measurement data becomes difficult due to vision obscuration
Solution Approach 1:
By positioning the display screen on the transverse section rather than along the longitudinal axis, the reading interface is moved to a different spatial dimension that is accessible to the operator's line of sight, eliminating vision obscuration issues.
3Measurement precision
If traditional measurement methods are used, then the device is simple to manufacture, but measurement accuracy is affected by subjective judgment and visual acuity errors
Solution Approach 1:
The patent replaces traditional mechanical scale reading with a digital display system that electronically presents measurement data. This substitution eliminates subjective judgment and visual acuity errors by providing objective digital readings.
Solution Approach 2:
The measurement data is copied from the physical measurement interface to a digital display screen, creating a separate representation that can be read without direct visual contact with the measurement point, thereby eliminating vision-related errors.

AI summary
An oral cavity restoration space measuring device and method. A depth measuring rod(6) and a main scale(5) are configured to be rigidly connected to each other; a gripping end and a measuring end are connected at a certain angle to reduce a measuring dead angle; a first detachable measuring claw(10) and a second detachable measuring claw(11) are used, and measurements of depth, width and length are integrated; and a digital display meter(4) can rotate around the axis of a connecting rod(9) so as to facilitate the viewing of displayed measurement data.
