Webbing Sling Support for Tractor Trailer Conduit Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for securing and supporting tractor-trailer conduit lines are inadequate, leading to damage from uncontrolled movement, restricted fluid flow, and frequent maintenance needs, as they are not effectively held in a stationary position, causing potential system failures and safety concerns.
Innovation Solution
A hose and cable sling support device comprising upper and lower portions with polyester webbing and a metal D-ring, providing secure, adjustable support loops that encircle conduit lines to prevent movement and exposure, ensuring optimal positioning and reducing wear, made from 100% polyester webbing with a 6,000-pound breaking strength and self-extinguishing properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If plastic injection molded clips are used to secure conduit lines, then the conduit lines are held in position, but the clips are rigid and line-size specific which limits functionality and can restrict fluid flow
Solution Approach 1:
The webbing-based support device is designed to be universally compatible with conduit lines of various sizes. The webbing material can accommodate different diameters through adjustment, eliminating the need for size-specific clips while maintaining secure positioning and preventing fluid flow restriction.
Solution Approach 2:
The support device utilizes webbing with adjustable parameters (width, length, tension) to adapt to different conduit line sizes. This allows the same device to effectively support various conduit diameters without restricting fluid flow, unlike rigid plastic clips that are fixed in size.
2Reliability
If plastic injection molded clips are used to secure conduit lines, then the conduit lines are held in position, but the clips can slide up and down during operation causing damage
Solution Approach 1:
The webbing material provides a cushioning effect between the support device and the conduit line. This cushioning prevents the harmful sliding and rubbing motions that occur with rigid clips, thereby protecting the conduit line from damage while maintaining positional stability during operation.
3Reliability
If molded clips grip conduit lines tightly to prevent movement, then positioning stability is improved, but pneumatic and hydraulic fluid flow is restricted
Solution Approach 1:
The webbing-based support device uses flexible thin film material to support conduit lines. This flexible construction provides positioning stability without the rigid constriction that restricts fluid flow in plastic clips, thereby preventing energy loss in pneumatic and hydraulic systems.
4Reliability
If metal clips with rubber grommets are used, then conduit lines are supported, but the rubber grommet fails and metal cuts into conduit lines
Solution Approach 1:
The webbing-based support device replaces the metal clip with a disposable webbing construction that lacks the cutting hazard. While webbing may wear over time, it provides continuous support without the risk of sudden metal exposure and cutting damage that occurs when rubber grommets fail on metal clips.
Solution Approach 2:
The support device utilizes composite material properties of webbing (combining strength, flexibility, and non-cutting characteristics) to provide conduit line support without the harmful metal cutting effect. This composite approach eliminates the need for metal components that could cut into conduit lines.
5Reliability
If existing connection options are used, then conduit lines are secured, but regular preventative maintenance and constant adjustment are required
Solution Approach 1:
The webbing-based support device is designed to be self-adjusting and self-maintaining. The flexible webbing automatically adapts to conduit line movement and positioning requirements without requiring manual adjustment or frequent maintenance, thereby reducing the time loss associated with regular preventative maintenance.
