Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The slip ring in radiographic inspection apparatuses of vehicle-mounted security systems can rotate due to vibrations during vehicle travel, potentially damaging the scanning device components.
Innovation Solution
A locking mechanism with a driving mechanism and contact portion is used to prevent the slip ring from rotating relative to the upright framework, featuring a resilient pad and buffer device to ensure stable contact and prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the radiographic inspection apparatus is provided in the box of the vehicle without a locking mechanism, then the device complexity is reduced, but the slip ring may rotate due to vibration during vehicle travel, causing damage to the scanning device components
Solution Approach 1:
The locking mechanism is activated before the vehicle starts moving to prevent the slip ring from rotating due to vibration. The driving mechanism drives the contact portion to contact the outer ring of the slip ring in advance, establishing a locked state that prevents subsequent rotation during vehicle travel.
Solution Approach 2:
The contact portion acts as an intermediary element between the driving mechanism and the slip ring. It transmits the locking force from the driving mechanism to the slip ring's outer ring, enabling the locking function while maintaining a simple overall structure.
2Reliability
If a locking mechanism with contact portion is added to prevent slip ring rotation, then the reliability of the scanning device is improved, but the device complexity increases due to additional components
Solution Approach 1:
The locking mechanism is segmented into distinct functional components: the driving mechanism for generating locking force, the contact portion for transmitting force to the slip ring, and the resilient pad for cushioning. This segmentation allows each component to be optimized for its specific function while maintaining overall simplicity.
Solution Approach 2:
The resilient pad is applied locally at the contact point between the contact portion and the slip ring's outer ring. This localized cushioning element provides vibration absorption and shock protection only where needed, without requiring complex damping systems throughout the entire装置.
3Device complexity
If the contact portion directly contacts the slip ring without a resilient pad, then the device complexity is reduced, but the risk of damage to the slip ring due to vibration and shock is increased
Solution Approach 1:
The resilient pad is installed in advance between the contact portion and the slip ring's outer ring to provide cushioning protection. This pre-installed damping element absorbs vibration and shock forces before they can reach and damage the slip ring, preventing harmful effects before they occur.
4Object-affected harmful factors
If the locking mechanism is designed with a resilient pad and buffer device, then the protection against vibration damage is improved, but the manufacturing complexity and cost increase
Solution Approach 1:
The resilient pad and buffer device change the mechanical parameters of the locking mechanism by introducing elasticity and damping characteristics. This allows the system to absorb vibration and shock through material properties rather than complex mechanical structures, simplifying manufacturing while improving protection.
