Dental X-ray Sensor Holder With Spring Arm Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dental X-ray sensor holders are often bulky and require time-consuming adhesive application, and some adhesives are not suitable for use in the oral cavity, necessitating a compact, inexpensive, and adhesive-free solution for securely holding X-ray detectors during procedures.
Innovation Solution
A dental X-ray sensor holder with a backing plate and sheath system that uses spring arms and a strap to removably secure the sensor, eliminating the need for adhesives and allowing for easy alignment and secure positioning of sensors for X-ray acquisition, with the strap tightening around the sensor to maintain its position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional adhesive methods are used to secure X-ray sensors to holders, then the sensor can be held in position, but the process becomes time-consuming and requires materials not suitable for oral cavity use
Solution Approach 1:
The invention extracts and eliminates the adhesive component from the sensor securing system, replacing it with a purely mechanical retention mechanism using spring arms and a retention member that physically holds the sensor in place without chemical bonding
Solution Approach 2:
The invention replaces the chemical bonding mechanism (adhesive) with a mechanical retention system consisting of spring arms and a retention member that uses elastic deformation and physical constraint to secure the sensor, thereby eliminating the need for adhesive application
2Reliability
If conventional holder designs are used, then sensors can be secured, but the holders become bulky and complex
Solution Approach 1:
The holder is segmented into distinct functional components: a bite block for patient comfort and positioning, spring arms for sensor retention, and a retention member for securing the sensor, allowing each component to be optimized independently and simplifying the overall structure
Solution Approach 2:
The spring arms provide dynamic retention through elastic deformation, allowing the holder to adapt to different sensor sizes and positions while maintaining secure retention, replacing rigid complex structures with flexible simple mechanisms
3Reliability
If adhesive-based securing methods are used, then sensors can be held securely, but the system becomes expensive and requires materials unsuitable for oral cavity
Solution Approach 1:
The retention member appears to be a simple, potentially disposable component that can be easily manufactured and replaced, eliminating the need for expensive adhesive materials and simplifying the manufacturing process while maintaining sensor security
