Pole Roller Wear Ring for Angled Sewer Hose Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pole rollers fail to efficiently advance a sewer hose and nozzle through pipelines that veer off at angles due to increased surface friction and drag, leading to reduced hose advancement and faster wear.
Innovation Solution
A lightweight, compact pole roller assembly with a protection wear ring and rotating roller design that minimizes friction and drag on angled pipeline surfaces, allowing the hose and nozzle to advance more efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current pole rollers are used in pipelines that veer off at angles, then the roller hits and rubs against the side surface of the pipeline, but this causes the roller to break and the hose to advance a shorter distance due to increased friction and drag
Solution Approach 1:
A protection wear ring is introduced as an intermediary component between the roller and the pipeline side surface. This wear ring absorbs the contact and friction when the roller hits the pipeline wall during angled veers, preventing direct damage to the roller while allowing the hose to continue advancing without significant friction increase
Solution Approach 2:
The protection wear ring serves as a pre-installed cushioning element that anticipates and absorbs the impact and friction forces that occur when the roller contacts the pipeline side surface during angled turns, preventing roller breakage before it happens
2Device complexity
If current pole rollers are used without protection wear rings, then the structure is simpler, but the roller breaks when hitting the side surface of angled pipelines
Solution Approach 1:
The protection wear ring is added as a relatively simple intermediary component that sits between the roller and the pipeline wall, providing durability enhancement without significantly complicating the overall pole roller structure
Solution Approach 2:
The protection wear ring is designed as a sacrificial, replaceable component that can wear out and be replaced independently of the main roller assembly, providing an economical solution to extend roller life in abrasive conditions
3Productivity
If the hose is propelled forward through the sewer pipeline, then cleaning is achieved, but more energy is required to continuously advance it forward due to friction, drag, weight, and gravity
Solution Approach 1:
The pole roller is designed with a rotating roller mechanism that dynamically adapts to the pipeline surface. The roller rotates freely as the hose is pulled forward, reducing static friction and allowing the hose to advance with minimal resistance along the pipeline bottom and side surfaces
Solution Approach 2:
The rotating roller mechanism replaces direct hose-pipeline surface contact that would create high friction. By introducing the roller as a mechanical intermediary that rotates rather than slides, the system reduces the energy required to propel the hose forward
4Adaptability or versatility
If the hose advances through pipelines that veer off at angles, then complete coverage is achieved, but the roller hits the side surface causing increased friction and faster hose wear
Solution Approach 1:
The protection wear ring acts as a mediator that absorbs the contact forces when navigating angled pipeline veers, preventing direct damage to the hose from roller-induced friction and allowing the system to maintain adaptability across various pipeline configurations
Solution Approach 2:
The wear ring provides pre-positioned cushioning at the roller-pipeline interface, protecting the hose from wear before contact occurs during angled turns, thereby extending hose lifespan while maintaining the ability to navigate complex pipeline layouts
