Segmented Cable Protector with Flexible Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cable protectors are expensive due to the need for interlocking joints in shorter polyurethane sections to conform to curved road surfaces, while softer materials like rubber and PVC offer longer lengths but are costlier for longer sections.
Innovation Solution
The apparatus consists of double-ended protector members with slanting tire engagement surfaces and a flexible high-friction backing that allows bending to conform to road surfaces, using low-cost materials like synthetic lumber for durability and weather resistance, and flexible connectors to maintain alignment without the need for interlocking joints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If polyurethane material is used for cable protectors, then strength and rigidity are improved, but the protector must be divided into shorter sections to conform to curved road surfaces, increasing device complexity and cost
Solution Approach 1:
The cable protector is divided into multiple modular sections that can be connected together. Each section has a standardized shape with connection features at the ends, allowing multiple sections to be assembled to cover different lengths and conform to curved road surfaces without requiring complex custom-shaped protectors.
Solution Approach 2:
The connector joining polyurethane sections incorporates a flexible material element (such as a rubber or elastomeric component) that provides flexibility to accommodate curved surfaces while the rigid polyurethane sections provide structural strength. This composite approach combines the advantages of both rigid and flexible materials.
2Adaptability or versatility
If rubber or PVC material is used for cable protectors, then flexibility and ability to conform to curved surfaces are improved, but cost increases for longer sections
Solution Approach 1:
The protector is segmented into multiple standardized sections rather than manufactured as one long continuous piece. This reduces the cost of manufacturing each section while the flexible connector material allows the assembled protector to conform to curved road surfaces, maintaining adaptability at lower cost.
Solution Approach 2:
The connector between rigid polyurethane sections incorporates a flexible material shell or film that allows the assembled protector to bend and conform to curved surfaces. This flexible element enables adaptability without requiring the entire protector to be made from expensive flexible materials like rubber or PVC.
3Length of stationary object
If interlocking joints are built into protector sections, then the ability to assemble longer protectors is improved, but manufacturing cost significantly increases
Solution Approach 1:
The protector is divided into standardized modular sections that can be assembled to achieve various lengths. Each section has simple connection features at the ends that allow straightforward assembly without complex interlocking joints, reducing manufacturing cost while enabling flexible length configuration.
Solution Approach 2:
The connector design serves multiple functions: it joins sections together to achieve desired length, provides flexibility to conform to curved surfaces, and simplifies assembly operations. This multi-functional connector reduces the need for complex specialized joints for each function.
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
This design provides a cost-effective solution for protecting cables from traffic damage by increasing friction and stability, reducing material costs through the use of flexible connectors and durable yet affordable materials, suitable for various traffic loads and road conditions.
Implementation Method 1
The force vector of a moving tire engaging a tire engagement surface will exert a downward force on the protector member urging the protector member in the direction of the support surface and increasing frictional force between the support surface and the protector member to resist slidable movement
Implementation Method 2
flexible connector structure attached to the plurality of protector members and extending between adjacent ends thereof to maintain the protector members disposed end to end while enabling bending to occur between adjacent protector members
