Telescopic Suspension Arm Damping for Shock-Resistant Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical imaging suspension devices experience high stress and rapid deterioration due to repeated shocks and oscillations when moving display screens, leading to a risk of the telescopic arm breaking and screens falling, especially when the screens are heavy.
Innovation Solution
Incorporation of a shock-absorbing or damping element between the telescopic arm and the mobile carriage to absorb vibrations and reduce bending stresses, using a combination of expanded polymer blocks and a ball-and-socket joint to dissipate energy and limit movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the size of component parts is increased to limit damage risks, then the reliability of the device is improved, but the device becomes costly and bulky
Solution Approach 1:
The patent introduces a damping element positioned between the mobile carriage and the telescopic arm that absorbs shocks before they can damage the arm. This cushioning element is designed to deform under impact forces, dissipating energy and protecting the structural components from damage without requiring oversized parts throughout the entire device.
2Reliability
If damping elements are added to absorb shocks, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The damping element serves as an intermediary component between the mobile carriage and the telescopic arm. It specifically targets the shock transmission path, absorbing impacts locally at the connection point rather than requiring complex protection throughout the entire arm structure. This localized approach adds minimal complexity while effectively protecting the critical arm component.

Function Achieved in This Case
The damping system effectively reduces stress on the telescopic arm, preventing damage and ensuring the stability of the display screens during operation, while maintaining a compact and cost-effective design.
Implementation Method 1
a shock-absorbing or damping element designed to damp any movement of the arm in relation to the mobile carriage
Implementation Method 2
the damping element limits the generation of bending stresses in the arm of the device
