Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional X-ray imaging apparatuses generate noise due to contact between guide rails and magnetic bodies during holding operations of the X-ray generator or detector.
Innovation Solution
An X-ray imaging apparatus with a holding unit that includes a contact pad to contact the guide rail, a magnetic body to move the contact pad using magnetic force, and a holding plate with layers of magnetic and rubber materials to absorb noise and vibration, allowing the contact pad to switch between holding and releasing positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a magnetic body directly contacts the guide rail to hold the moving carriage, then the holding force is sufficient, but noise and vibration are generated
Solution Approach 1:
A contact pad made of elastic material is introduced as an intermediary between the magnetic body and the guide rail. The contact pad deforms elastically under magnetic attraction, providing continuous contact force to hold the moving carriage while absorbing impact and reducing noise. This mediator allows the system to maintain reliable holding force without the harmful direct contact noise.
Solution Approach 2:
The holding unit employs a composite structure combining magnetic material (for attraction force) and elastic material (for noise absorption). The magnetic body generates the holding force while the elastic contact pad provides cushioning, creating a composite system that simultaneously achieves strong holding capability and noise reduction.
2Stability of the object's composition
If the contact pad continuously contacts the guide rail, then the holding position is stable, but wear and noise occur
Solution Approach 1:
The elastic contact pad serves as a pre-installed cushioning element between the moving carriage and guide rail. Before any potential impact or wear occurs, the elastic material is already in place to absorb shocks and distribute contact forces, preventing direct metal-to-metal contact and reducing both wear and noise during operation.
Solution Approach 2:
The contact pad changes its physical parameters (deformation, contact area, stiffness) in response to operational conditions. Under normal holding conditions, it maintains stable elastic deformation for position stability. During movement or impact, it increases deformation to absorb energy, dynamically adjusting its properties to balance stability with wear and noise reduction.
