Solution Overview

Problem

Existing transportable masts are either heavy, complex, and expensive to manufacture, or they lack stability and ease of setup due to their design, which complicates their rotation and alignment during antenna or equipment support.

Innovation Solution

A mast assembly with a guide shaft comprising a tubular pipe and multiple leg attachment collars made of optimized materials for strength and low friction, allowing for easy sliding and alignment of mast sections, and a guy control assembly for stabilization, enabling quick setup and retraction by a single person.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a single casted block is used for the supporting structure, then strength and stability are improved, but weight and manufacturing difficulty increase

Engineering Contradiction:
ImprovestrengthVSAvoidweight
Core Design Contradiction:
StrengthVSWeight of stationary object

Solution Approach 1:

The supporting structure is divided into multiple components: a base plate, vertical support elements, and connection elements. This segmentation allows each part to be manufactured separately using lighter materials and assembled together to achieve the required strength, eliminating the need for a heavy single casted block while maintaining structural integrity.

Inventive Principle:
Principle #1Segmentation

2Stability of the object's composition

If a single casted block is used for the supporting structure, then stability is improved, but manufacturing complexity increases

Engineering Contradiction:
ImprovestabilityVSAvoidmanufacturing complexity
Core Design Contradiction:
Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The structure is segmented into standardized components that can be manufactured using common fabrication processes and assembled through simple connections, greatly reducing manufacturing complexity compared to a single casted block while maintaining stability through proper structural design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple functional elements are merged into integrated components where possible, such as combining mounting surfaces, support functions, and connection features into unified elements, simplifying the overall structure while maintaining stability.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If friction reducing material is added to guide displacement, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improveease of operationVSAvoidcomplexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

Friction-reducing properties are applied locally at specific contact surfaces where guidance and sliding occur, such as using low-friction coatings or materials only on the guiding surfaces, rather than adding complex mechanical friction-reducing components throughout the structure.

Inventive Principle:
Principle #3Local quality
