Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vertical surface drones face limitations in mobility on surfaces where vacuum generation is impossible or difficult, such as rough or hollow structures, and they consume excessive power due to motor-driven vacuum systems.
Innovation Solution
A drone that uses compressed air from a reservoir or compressor to generate force against vertical surfaces via adjustable nozzles, eliminating the need for vacuum and reducing power consumption by decentralizing the motor system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If vacuum-based systems are used to attach the device to the wall, then the device can stabilize on vertical surfaces, but it cannot move on surfaces that are too rough or hollow where vacuum generation is impossible
Solution Approach 1:
The patent replaces vacuum-based attachment with a pneumatic system that uses compressed air delivered through hoses to the device. The compressed air is discharged through nozzles oriented against the wall surface, creating a pressure force that presses the device against the wall. This pneumatic approach works on all surface types including rough or hollow surfaces where vacuum generation fails, as it directly applies pressure rather than attempting to create a vacuum seal.
2Reliability
If motor-driven vacuum systems are used to generate suction, then the device can attach to vertical surfaces, but power consumption becomes excessive
Solution Approach 1:
The patent uses a pneumatic system with compressed air delivered through hoses, which consumes significantly less power than motor-driven vacuum systems. The compressed air can be supplied from external sources such as building ventilation systems, allowing the device to attach to vertical surfaces without requiring high-power motors, thus reducing overall power consumption while maintaining attachment stability.
3Ease of operation
If vacuum systems are used to move the device along the wall, then the device can maintain attachment, but it cannot operate on surfaces where vacuum generation is impossible
Solution Approach 1:
The patent employs a pneumatic propulsion system where compressed air is delivered through hoses to the device, and nozzles are oriented to discharge air against the wall surface. This creates a pressure force that propels the device along the wall while maintaining attachment. This system operates on all surface types including rough or hollow surfaces, providing both mobility and surface compatibility where vacuum systems fail.
