Rotatable Antenna Mounting for Vehicle Maintenance Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for fixing antennas to vehicle chassis are time-consuming and require frequent repositioning during maintenance, hindering efficient communication and increasing downtime in public transport systems.
Innovation Solution
A rotatable antenna support system that allows access behind the antenna without dismantling it, enabling precise repositioning without repeating tedious test and adjustment phases, by pivoting the antenna on its support and maintaining optimal communication alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the antenna is fixed to the vehicle chassis, then optimal communication positioning is achieved, but access to equipment behind the antenna is restricted
Solution Approach 1:
The support structure is made rotatable relative to the base, transforming a static antenna mounting into a dynamic system. This allows the antenna to be rotated between different positions (first position for communication, second position for equipment access) while maintaining stable mounting through the rotatable connection between support and base.
2Ease of repair
If the antenna is removed to access equipment behind it, then equipment maintenance is enabled, but the antenna must be repositioned requiring time-consuming testing
Solution Approach 1:
The rotatable support structure is prepared in advance with multiple fixing positions. When equipment maintenance is needed, the antenna can be quickly rotated to the second position without removal. After maintenance, the antenna is rotated back to the first position, eliminating the need for time-consuming repositioning tests since the pre-configured rotational mechanism preserves positioning accuracy.
3Reliability
If the antenna is positioned on the exterior of the vehicle, then communication with ground-based devices is optimized, but access to nearby equipment is difficult
Solution Approach 1:
The antenna mounting system incorporates a rotatable support that enables the antenna to be dynamically repositioned. In the first position, the antenna extends outward for optimal communication. In the second position, the antenna is rotated to allow access to equipment behind it, thus resolving the contradiction between communication optimization and equipment accessibility.
4Ease of repair
If frequent antenna repositioning is performed during maintenance, then equipment servicing is enabled, but communication reliability deteriorates due to repeated testing requirements
Solution Approach 1:
The rotatable support with pre-configured fixing positions allows the antenna to be quickly repositioned during maintenance without compromising its mounting precision. The multiple second holes and corresponding first holes enable the antenna to be secured at different positions while maintaining optimal alignment, thus preserving communication reliability even during frequent maintenance operations.
