X-ray Detector Buffer Beams for Shock Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing X-ray imaging apparatuses face issues with shock resistance and external environment stability due to the direct transmission of shocks to the X-ray detector assembly when it is rigidly fixed, and the use of cushions for shock absorption complicates precise positioning and reliability.
Innovation Solution
A portable detector panel with a buffer member made of hard, flexible material is integrated between the case and the X-ray detector assembly, featuring cantilever beams or straddle-mounted beams that absorb shocks and vibrations, maintaining precise positioning and stability without the need for cushions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the X-ray detector assembly is rigidly fixed to the case via a hard material spacer, then the positioning precision is improved, but the shock resistance deteriorates as shocks are directly transmitted to the detector
Solution Approach 1:
The buffer member is divided into multiple beam structures (first beam, second beam, third beam, fourth beam) arranged at different positions. Each beam can independently absorb shock energy through elastic deformation, providing distributed shock protection while maintaining positioning precision through the structured arrangement of these segments.
Solution Approach 2:
The buffer member utilizes elastic deformation of beam structures to dynamically absorb shock energy. The beams can flex and deform elastically under impact forces, converting kinetic energy from shocks into elastic potential energy, thereby protecting the detector assembly from direct shock transmission while returning to their original position to maintain positioning accuracy.
2Object-affected harmful factors
If a cushion is arranged below the spacer to absorb shock, then the shock resistance is improved, but the reliability deteriorates due to temperature characteristics and external vibration affects
Solution Approach 1:
The patent replaces the traditional soft cushion material with a hard material buffer member consisting of beam structures. This substitution eliminates the reliability issues associated with cushion materials (temperature sensitivity, vibration effects) while maintaining shock absorption capability through the elastic deformation mechanism of the beam structures.
Solution Approach 2:
The buffer member is constructed using hard material that combines rigidity with elastic deformation capability. This composite approach uses the inherent elastic properties of the hard material to provide both shock absorption and environmental stability, eliminating the need for separate soft cushioning materials that are sensitive to temperature and vibration.
3Object-affected harmful factors
If a cushion is interposed between the case and detector assembly, then the shock resistance is improved, but the manufacturing precision deteriorates due to difficulty in precise positioning
Solution Approach 1:
The buffer member is segmented into multiple beams positioned at specific locations (first beam at first position, second beam at second position, etc.). This segmentation allows each beam to be precisely positioned and fixed at predetermined locations, ensuring accurate positioning of the detector assembly while collectively providing shock absorption through elastic deformation of individual beams.
