Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote manipulation systems for elastic collars are complex and costly to manufacture, with delicate assembly and maintenance requirements, and do not allow for easy replacement or prefabrication of sheath-cable assemblies.
Innovation Solution
A remote manipulator with a fixed jaw and mobile jaw, actuated via a cable and flexible sheath, featuring interchangeable sleeves that allow easy clipping and sliding of the cable or sheath ends, enabling simpler assembly and maintenance, and allowing prefabrication of the sheath-cable assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cable is fixed to one arm and slides inside a flexible sheath with one end abutting on the fixed jaw, then remote actuation of the mobile jaw is achieved, but the assembly and maintenance of the sheath-cable assembly become delicate and complicated
Solution Approach 1:
The invention divides the sheath-cable assembly into separable components: the sheath is divided into two portions that can be independently assembled to each arm, and the cable is divided into two ends that can be separately secured. This segmentation allows each component to be independently replaced or maintained without affecting the entire assembly, thereby reducing assembly complexity while preserving remote actuation capability.
Solution Approach 2:
The sheath portions and cable ends are pre-configured with securing mechanisms (such as eyes, loops, or attachment points) that enable preliminary assembly before final installation. This preliminary preparation simplifies the overall assembly process and facilitates quick replacement during maintenance, addressing the complexity issue while maintaining operational capability.
2Ease of operation
If the cable is fixed to one arm and slides inside a flexible sheath, then remote manipulation is enabled, but quick replacement of damaged cable or sheath is not possible
Solution Approach 1:
By dividing the sheath into two separate portions and the cable into two ends, the invention enables independent replacement of damaged components. If one portion of the sheath or one end of the cable is damaged, only that specific component needs to be replaced rather than the entire assembly, significantly improving ease of repair while maintaining remote manipulation functionality.
Solution Approach 2:
The invention introduces dynamic, reversible connection mechanisms between the sheath portions and cable ends to the arms, allowing for quick attachment and detachment. This dynamic connection system enables rapid replacement of damaged components without complex disassembly procedures, thereby improving ease of repair while preserving the remote manipulation capability.
3Ease of operation
If the cable is fixed to one arm and slides inside a flexible sheath, then actuation is achieved, but prefabricated sheath-cable assemblies cannot be easily marketed
Solution Approach 1:
The invention segments the sheath-cable system into independent, interchangeable portions that can be pre-assembled and tested separately before final installation. This segmentation allows manufacturers to produce standardized, prefabricated sheath portions and cable ends that can be库存ed and quickly assembled into complete remote manipulator systems, thereby enabling easier marketing of prefabricated assemblies while maintaining actuation functionality.
Solution Approach 2:
The invention creates universal connection interfaces between the sheath portions, cable ends, and arms that can accommodate different configurations and applications. This universality allows a single design of prefabricated sheath-cable assemblies to serve multiple purposes and be easily marketed across different use cases while preserving the core actuation functionality.
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
Facilitates easier and less expensive manufacturing, allows for quick replacement of damaged components, and enables the use of prefabricated sheath-cable assemblies, improving maintenance and reducing assembly complexity.
Implementation Method 1
a cable (2) secured to one end of said slider (6) and sliding inside a flexible sheath (3)
Implementation Method 2
Said ring is naturally capable of deforming by separating its two ends which creates an elastic return torque used as clamping
