Segmented Skate Truck for Cable Guide Flexion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional skate trucks are rigid and unable to adapt to vertical and horizontal flexions of cable guides, leading to excessive force and potential damage to the cable guide and skate truck.
Innovation Solution
A skate truck comprising a plurality of interconnected skate units with rollers and connectors that allow vertical articulating and lateral movement, enabling the truck to accommodate flexions and snaking movements of the cable guide, thereby preventing damage and facilitating maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional rigid skate trucks are used, then structural strength is maintained, but the cable guide cannot adapt to vertical and horizontal flexions, leading to excessive force and potential damage
Solution Approach 1:
The skate truck is divided into multiple skate units (first skate unit, second skate unit, third skate unit, etc.) connected by connectors. Each skate unit can move independently, allowing the overall structure to adapt to vertical and horizontal flexions while maintaining structural integrity through the interconnected design
Solution Approach 2:
The connectors are designed to allow dynamic movement between skate units. The first connector permits vertical articulating movement, while the second connector permits horizontal lateral movement. This dynamic capability enables the rigid skate truck structure to accommodate cable guide flexions without compromising structural strength
2Adaptability or versatility
If rigid connections are used between skate units, then structural stability is maintained, but the skate truck cannot accommodate cable guide flexions, resulting in excessive force
Solution Approach 1:
The connectors are designed with specific movement capabilities: the first connector allows vertical articulating movement between skate units, and the second connector allows horizontal lateral movement. This dynamic design provides flexibility to accommodate cable guide flexions while maintaining structural stability through controlled movement paths
Solution Approach 2:
The connectors act as intermediaries between adjacent skate units, mediating the forces generated by cable guide flexions. They transmit necessary forces while allowing appropriate movements, preventing excessive force transmission to the cable guide and maintaining overall structural stability
3Reliability
If the skate truck is made flexible to accommodate flexions, then damage prevention is improved, but the structure becomes more complex
Solution Approach 1:
The skate truck is segmented into multiple skate units connected by specialized connectors. This segmentation allows each unit to remain relatively simple in structure while the collective system achieves the flexibility needed for damage prevention through coordinated movement of individual units
Solution Approach 2:
The dynamic connectors add movement capability without significantly increasing overall complexity. Each connector has a specific function (vertical articulation or horizontal lateral movement), and the modular design allows these dynamic elements to be integrated systematically across multiple skate units
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
The flexible skate truck effectively reduces strain on the cable guide and itself, preventing deformation and damage, while allowing for smooth movement and easier maintenance by accommodating vertical and horizontal flexions.
Implementation Method 1
The rollers are rotatably mounted on the frame on parallel horizontal axes for rolling contact with mutually facing parts of a cable guide

AI summary
A skate truck for interposition between two mutually facing parts of a flexible cable guide is composed of plural skate units interconnected to one another by interconnecting members that allow both vertical articulation and lateral movement of the skate units relative to the interconnecting members and relative to adjacent skate units.
