Portable Radiation Generator With Guide Light for Intra-Oral Targeting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable radiation generators face challenges in accurately targeting the imaging area due to difficulty in aligning the X-ray radiation direction with the imaging point within the oral cavity, especially for unskilled users, leading to imprecise intra-oral X-ray imaging.
Innovation Solution
A portable radiation generator with a collimating unit and a light radiating unit that emits guide light to indicate the radiation center and range, using a radiolucent radiating plate to ensure precise targeting, and a control unit to manage the radiation and light operations, including multiple guide light colors for different device states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a portable radiation generator is used for intra-oral X-ray imaging, then ease of operation is improved, but precision of radiation targeting deteriorates
Solution Approach 1:
A guide light is introduced as an intermediary visual indicator between the radiation source and the imaging area. The guide light emits visible light that coincides with the radiation beam path, allowing users to visually identify and accurately target the imaging area without requiring complex alignment mechanisms or skilled operation
Solution Approach 2:
The guide light utilizes visible light emission to provide visual feedback on the radiation beam path. By making the invisible radiation beam visible through the guide light, users can easily identify the precise imaging area and adjust positioning accordingly, resolving the contradiction between ease of operation and targeting precision
2Weight of moving object
If the imaging range is made small for portable use, then portability is improved, but difficulty of detecting and measuring the imaging point increases
Solution Approach 1:
The guide light serves as a visual intermediary that makes the small imaging area detectable. By emitting visible light that overlaps with the radiation beam, the guide light amplifies the visibility of the imaging point, allowing users to easily locate and measure the precise imaging area even when the range is limited for portable use
