Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flying robots face limitations in flight duration, weight capacity, and human-machine interaction due to high power consumption and noise, as well as restricted movement range and interaction capabilities compared to ground robots.
Innovation Solution
A flying robot with a distributed design featuring a movable end and a fixed end in wireless communication, where the movable end uses a spherical body filled with gas for buoyancy and a lift system with fans to generate lift, and incorporates projectors for human-machine interaction, reducing weight and power consumption while enabling long flight durations and enhanced interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the flying robot carries additional apparatus such as display and interaction devices, then the interaction capability is improved, but the weight increases and flight duration is shortened
Solution Approach 1:
The system is divided into a flying robot portion and a ground station portion. The flying robot carries only essential lightweight components (projector, basic controllers), while heavier equipment (display devices, complex processing units, communication apparatus) are placed on the ground station. This segmentation allows the flying robot to maintain long flight duration while still providing comprehensive interaction capabilities through the distributed system.
2Force
If the propellers rotate at high speed to generate sufficient power, then the lift capability is improved, but the noise increases and safety deteriorates
Solution Approach 1:
The patent employs buoyancy as a counterweight force to offset part of the flying robot's weight. By using a gas-filled buoyant structure, the system reduces the net weight that propellers need to lift, thereby allowing slower propeller rotation speeds that generate less noise and reduce safety hazards while maintaining adequate lift capability.
3Ease of operation
If the flying robot is designed with small volume to move close to ground, then the movement flexibility is improved, but the display size is limited and visual angle is reduced
Solution Approach 1:
The display function is extended from the flying robot to the ground station, utilizing the two-dimensional space of the ground-based display device. This allows the display size to be much larger than what could be mounted on the flying robot, while the flying robot maintains its small volume and movement flexibility by focusing on flight and basic interaction functions.
4Quantity of substance
If the power system is increased to carry heavier load, then the load capacity is improved, but the power consumption increases and flight time is reduced
Solution Approach 1:
Heavy equipment and power-consuming components are extracted from the flying robot and placed on the ground station. The flying robot retains only essential lightweight components, significantly reducing its weight and power consumption requirements. This allows the system to maintain adequate load capacity for interaction devices while extending flight time by eliminating the need to power heavy equipment on the flying robot.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for extended flight times, reduced noise, and improved human-machine interaction through efficient power management and the use of projectors for large-area display, addressing the limitations of existing flying robots.
Implementation Method 1
The interior of the main body is filled with a gas having a density less than that of the air, and the gas therein maintains a certain pressure to keep the surface of the main body smooth. As such, when the main body is full of the gas, the main body is applied a certain buoyant force in the air.
Implementation Method 2
the top comprises a lift system for providing a lift force needed when the movable end is flying
Implementation Method 3
the projector is configured to project images to the main body that visible from outside
