Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Robotic arm assemblies are often cost-prohibitive and overly complex for certain applications, making it difficult to reach remote or hazardous locations efficiently.
Innovation Solution
A selectively flexible extension tool with a plurality of sequentially arranged links that can move between a slacked and tensioned position, featuring separate fluid flow passages and a line assembly to facilitate movement and fluid flow, allowing for rigid fixation and fluid isolation when tensioned, enabling efficient access to remote locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If robotic arm assemblies are used to reach remote locations, then the ability to access remote or hazardous locations is improved, but the cost and device complexity increase significantly
Solution Approach 1:
The extension tool is divided into multiple sequentially arranged links that can be individually controlled to move between extended and retracted positions. This segmentation allows the tool to reach remote locations while maintaining a simpler, more cost-effective structure compared to traditional robotic arms.
2Length of moving object
If robotic arm assemblies are used to reach remote locations, then the ability to access remote or hazardous locations is improved, but the cost increases significantly
Solution Approach 1:
The tool uses segmented links with simple mechanical actuation mechanisms that are easier and less expensive to manufacture compared to complex robotic arm assemblies. Each link can be produced independently using standard manufacturing processes.
Solution Approach 2:
The extension tool utilizes self-contained actuators within each link that operate independently, eliminating the need for complex external control systems and reducing overall manufacturing costs while maintaining the ability to reach remote locations.
3Length of moving object
If the extension tool uses multiple sequentially arranged links, then the ability to reach remote locations is improved, but the device complexity increases
Solution Approach 1:
The extension tool employs a segmented link structure where each link is a self-contained module with integrated actuation. This modular segmentation achieves extended reach while keeping each individual component simple and the overall system manageable in complexity.
Solution Approach 2:
The links are designed to be movable relative to one another, transitioning between extended and retracted positions as needed. This dynamic configuration allows the tool to adapt its length and shape to reach remote locations without requiring a permanently complex mechanical structure.
4Adaptability or versatility
If the extension tool maintains flexibility through movable links, then the ability to navigate complex paths is improved, but the structural stability decreases
Solution Approach 1:
The extension tool utilizes dynamically movable links that can transition between flexible and rigid configurations. When extended, the links maintain relative movement capability for navigation; when retracted, they form a stable, rigid structure for operational stability.
Solution Approach 2:
The structural parameters of the extension tool change based on the position of the links. In the extended position, the system prioritizes flexibility for navigation; in the retracted position, it prioritizes structural stability for operations, achieving both requirements through parameter variation.
