Patch Antenna Cushioning Structure Against Shock and Vibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When an antenna device receives shock or vibrations, the patch antenna may contact the inner wall surface of the exterior body, leading to potential damage.
Innovation Solution
The antenna device incorporates an elastic body disposed between the exterior body and the patch antenna, acting as a cushion to absorb shocks and vibrations, thereby preventing damage to the patch antenna.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the patch antenna is accommodated in the exterior body without additional protective structures, then the device complexity is reduced, but the reliability deteriorates due to potential damage from shock or vibrations
Solution Approach 1:
The patent applies beforehand cushioning by introducing an elastic body between the patch antenna and the exterior body before shock or vibration occurs. This elastic body acts as a pre-positioned protective element that absorbs impact energy, preventing direct contact between the antenna and the hard exterior body surface, thereby resolving the contradiction between simple structure and damage resistance.
Solution Approach 2:
The elastic body serves as an intermediary element between the patch antenna and the exterior body. It mediates the interaction during shock or vibration events, providing a compliant interface that protects the antenna while maintaining structural integrity. This intermediary approach allows the simple structure to achieve enhanced reliability.
2Reliability
If an elastic body is added between the exterior body and the patch antenna, then the reliability improves by suppressing damage from shock or vibrations, but the device complexity increases
Solution Approach 1:
The elastic body is positioned in advance between the antenna and exterior body to provide protective cushioning before impact occurs. This simple protective addition enhances reliability without requiring complex active protection systems, achieving damage resistance with minimal structural complexity.
Solution Approach 2:
The elastic body functions as a flexible protective element that deforms under shock or vibration to absorb energy. This flexible component provides effective protection while maintaining a simple overall structure, avoiding the need for complex rigid protection mechanisms.
