Rotatable Mast Locking Assembly for Safe Single-Tech Service
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mast structures for wireless signal reception and transmission are costly to install and maintain due to their heavy and bulky construction, requiring multiple technicians and specialized tools to prevent accidental collapse during service, which poses risks to technicians and equipment.
Innovation Solution
A mast assembly with a rotatable hub and receiver system that allows the mast to be securely locked in a deployed position and easily lowered to a service position, featuring a base with a hub and receiver configuration that prevents unwanted rotation, enabling single-technician operation and reducing installation and maintenance costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional heavy and bulky mast construction is used, then structural strength and stability are improved, but installation and maintenance costs increase, and multiple technicians are required
Solution Approach 1:
The mast is divided into multiple sections that can be assembled in a telescopic configuration. Each section is supported by independent struts that can be individually adjusted and locked, allowing the mast to achieve full structural strength only when needed while reducing weight and complexity during installation and maintenance phases.
Solution Approach 2:
The mast structure transitions from a static heavy framework to a dynamic telescopic system where struts and support members can be extended or retracted based on operational requirements. This allows the structure to provide full strength during operation while minimizing material usage during installation and service.
2Stability of the object's composition
If traditional antenna mast mechanisms are used, then vertical positioning is achieved, but ancillary means such as additional service technicians or purpose built tools are required to prevent sudden dropping
Solution Approach 1:
The mast incorporates self-locking mechanisms in its telescopic sections and strut support systems that automatically engage when sections are extended or positioned. These mechanisms provide inherent stability and prevent accidental collapse without requiring additional technicians or specialized tools to maintain the structure during service operations.
Solution Approach 2:
The design includes pre-positioned locking mechanisms and support struts that are engaged before the mast is fully assembled or before service operations begin. This preparatory locking provides inherent stability and prevents sudden dropping during installation or maintenance, eliminating the need for ancillary safety measures.
3Stability of the object's composition
If heavy metal support trusses are used, then mast stability is improved, but the mast becomes costly to install and maintain
Solution Approach 1:
Instead of using heavy metal trusses throughout the entire mast structure, the invention applies structural support elements (struts, braces, and locking mechanisms) only at critical locations where stability is needed. The telescopic sections between these support points use lighter materials, reducing overall material quantity while maintaining mast stability through strategically placed reinforcement.
