Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Robotic arm assemblies are often cost-prohibitive and overly complex for certain applications, making it difficult to efficiently reach remote or hazardous locations within environments.
Innovation Solution
A selectively flexible extension tool with a plurality of sequentially arranged links and a support member, featuring bends and windows, allowing for controlled insertion and communication between internal and external environments, reducing friction and enabling access to remote locations with improved inspection and maintenance capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a robotic arm assembly is used to reach remote locations, then access capability is improved, but cost and device complexity increase
Solution Approach 1:
The extension tool is divided into multiple sequentially arranged links that can move relative to one another, allowing the tool to navigate complex geometries while maintaining a simple overall structure. Each link is a basic component that can be easily manufactured and replaced.
Solution Approach 2:
The links are designed to be moveable relative to one another, enabling the extension tool to dynamically adapt its shape to reach remote locations. The tool transitions from a flexible insertion state to a more rigid operational state as needed.
2Ease of operation
If control wires are used in robotic arm assemblies, then movement control is improved, but device complexity and cost increase
Solution Approach 1:
The patent removes the complex control wire and motor system from the base and instead provides simple manual operation capability, extracting the essential control function while eliminating unnecessary complexity and cost.
3Stability of the object's composition
If a rigid extension tool is used, then structural stability is improved, but insertion difficulty and surface damage risk increase
Solution Approach 1:
The extension tool uses moveable links that allow the tool to flex during insertion to navigate complex geometries, then maintain structural stability when positioned for operation. The dynamic structure adapts to insertion requirements while preserving operational rigidity.
Solution Approach 2:
The tool incorporates bends and curved geometries in the link arrangements, allowing it to follow curved insertion paths and navigate around obstacles without requiring excessive force, thereby reducing surface damage risk while maintaining stability.
4Measurement precision
If windows are added to links for communication, then inspection capability is improved, but device complexity increases
Solution Approach 1:
Windows are added only to specific links where inspection or communication with the external environment is needed, rather than making the entire tool complex. Each link maintains its simple basic structure with localized modifications only where required.
