Imaging Apparatus Movable Arm Mechanism Collision Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging apparatuses are difficult to move and often collide with walls or obstacles due to their fixed imaging elements, which limits their mobility and usability in various surgical and medical imaging applications.
Innovation Solution
A movable wheeled platform with a swingable arm mechanism and a sub-arm that can shift the imaging element between the front and rear sides of the platform, preventing collisions and elongation of the arm members, allowing for flexible positioning and safe movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the imaging element is fixed in the front side of the wheeled platform, then the imaging apparatus can be moved to arbitrary locations, but the imaging element collides with walls and obstacles during movement
Solution Approach 1:
The imaging element is made movable relative to the wheeled platform through a swingable arm mechanism. The arm can swing between a horizontal position (for imaging) and a vertical position (for movement), allowing the system to adapt its configuration based on whether it is being moved or used for imaging, thus preventing collisions while maintaining mobility.
2Adaptability or versatility
If the arm mechanism is extended to reach imaging positions, then imaging at arbitrary locations is enabled, but the arm members become vulnerable to collision and damage
Solution Approach 1:
The arm mechanism is designed to swing between horizontal and vertical positions. During movement, the arm is retracted to a vertical position close to the platform, protecting it from collision. During imaging, the arm extends to the horizontal position to reach the required imaging locations, thus balancing reach and protection.
Solution Approach 2:
The arm mechanism is preliminarily positioned in a protected vertical state during movement phases, preventing potential collision damage before it can occur. This preliminary protective positioning is maintained until the imaging operation actually requires the arm to extend.
3Reliability
If the imaging element is made movable to prevent collisions, then the apparatus can be safely moved, but the structural complexity increases
Solution Approach 1:
A swingable arm mechanism is introduced that can rotate between horizontal and vertical positions. This dynamic configuration allows the imaging element to be protected during movement while remaining accessible for imaging, resolving the contradiction between safety and complexity through a relatively simple rotational joint.

AI summary
An imaging apparatus that is easily moved between locations protects an imaging element in motion and provides a first arm member and a proximate movable second arm member. A lighting-imaging element is movably positionable proximate an arm mechanism and also proximate a rear-side location of a wheeled platform relative to a traveling direction thereby preventing damage. The first and second arm are relatively surrounded with a sub-arm and lighting-imaging element, thereby preventing further unintended movement. Accordingly, an elongating (separation) of the first and second arm members are prevented.
