Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telescopic rods, such as those using hydraulic pressure, face issues with weight increase due to pressure oil leakage and difficulty in extension, which complicates their use for applications like photography from high places.
Innovation Solution
A telescopic rod that extends axially by forcibly fed gas, incorporating a posture control means such as gas discharge mechanisms, counterweights, or rotary blades, allowing for easy extension and stabilization, and can be equipped with detachable flight vehicles for posture control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If hydraulic pressure is used to extend the telescopic rod, then the extension force is sufficient, but the weight increases due to pressure oil leakage mechanisms
Solution Approach 1:
The patent replaces the hydraulic pressure system with a pneumatic system that uses gas pressure to extend the telescopic rod. This eliminates the need for heavy pressure oil leakage mechanisms while maintaining sufficient extension force. The gas pressure system is inherently lighter and avoids the complexity of hydraulic fluid containment.
Solution Approach 2:
The patent changes the physical state parameter from liquid (hydraulic oil) to gas (compressed air or other gases) to achieve the same extension function. This parameter change reduces the weight of the system while maintaining the necessary force for extension, as gases can be stored in lighter containers and do not require the same level of containment precision as hydraulic systems.
2Ease of operation
If hydraulic pressure mechanism is added to the telescopic rod, then the extension capability is improved, but the device complexity increases
Solution Approach 1:
The patent simplifies the extension mechanism by using a pneumatic system with gas pressure instead of a complex hydraulic system. The gas pressure can be directly applied to extend the telescopic rod without requiring complex valves, pumps, and fluid management systems, thereby reducing device complexity while maintaining ease of operation.
Solution Approach 2:
The telescopic rod design allows the gas pressure system to self-regulate the extension process. The compressed gas naturally expands to provide the necessary extension force without requiring complex control mechanisms, and the system can automatically manage the pressure distribution across multiple telescopic sections.
3Device complexity
If the telescopic rod is extended using conventional methods, then the structure is simple, but the ease of extension is reduced
Solution Approach 1:
The patent introduces a gas pressure system that provides automatic extension capability. When gas is supplied to the telescopic rod, the pressure automatically drives the sections to extend without requiring manual manipulation or complex mechanical triggers, significantly improving ease of extension while maintaining relatively simple structure.
Solution Approach 2:
The telescopic rod incorporates a dynamic extension mechanism where the gas pressure system allows the structure to transition from a static, manually-operated system to a dynamically responsive system that can extend quickly and easily upon gas supply, improving operational ease without excessive structural complexity.
