Solution Overview

Problem

Existing high-place observation devices face instability when extending poles to great heights, as they can bend and oscillate due to gusts and air currents, making fixed-point observation challenging, especially at heights of several tens of meters.

Innovation Solution

A high-place observation device featuring a long rod-shaped body with a floating force generating means, such as a rotorcraft or gas balloon, and a maintaining mechanism like a winding mechanism with a reel, allows for stable positioning and fixation of the rod-shaped body at desired heights, suppressing bending and swinging.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If the pole is extended to a height position of several tens of meters to image the target object, then the observation height is improved, but the pole bends and oscillates due to gusts and air currents, making stable observation difficult

Engineering Contradiction:
Improvepole heightVSAvoidpole stability
Core Design Contradiction:
Length of moving objectVSStability of the object's composition

Solution Approach 1:

The pole is divided into multiple pole pieces that can be extended and contracted independently. This segmentation allows the pole to achieve greater height while maintaining structural stability, as each segment can be managed separately to reduce oscillation and bending at extreme heights.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The pole structure is designed to be dynamically extendable and contractible, allowing it to adapt its length based on observation requirements. The pole can be extended to reach high positions for imaging and then contracted or adjusted to minimize the effects of wind and air currents, thereby maintaining stability during operation.

Inventive Principle:
Principle #15Dynamics

2Stability of the object's composition

If the pole diameter is increased to reduce bending and oscillation, then the stability is improved, but the device complexity and weight increase

Engineering Contradiction:
Improvepole stabilityVSAvoidpole structure complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

Instead of using a single thick pole, the structure is segmented into multiple pole pieces of varying diameters. This allows optimization of each segment's thickness based on its specific structural requirements, achieving necessary stability without uniformly increasing the overall device complexity and weight.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different pole pieces have different diameters optimized for their specific positions and functional requirements. The pole pieces closer to the base can be thicker for structural support, while upper sections can be thinner, reducing overall weight and complexity while maintaining stability where most critical.

Inventive Principle:
Principle #3Local quality
