Modular Conduit Heater Assembly for Fast Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric heater systems for fluid conduits, such as heat trace cables, are time-consuming to install and replace, especially in continuous manufacturing processes, and require custom-made prefabricated heat-traced pipes that increase inventory and maintenance costs.
Innovation Solution
A modular heater system comprising a carrier member with a heating element and a thermal insulation jacket, featuring self-locking upper and lower portions with mating features, air gaps, and shims for easy assembly and alignment, along with a terminal box for electrical connection, allowing for scalable and cost-effective heating solutions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If heat trace cables are fastened to conduits with bands or retaining straps, then the heating function is achieved, but the installation time and labor burden increase significantly
Solution Approach 1:
The patent combines the heating element, mounting structure, and electrical connection components into a single integrated heat trace cable assembly. This merging eliminates the need for separate bands, retaining straps, and connection hardware, allowing the entire heating system to be installed as one unit, thereby dramatically reducing installation time and labor while maintaining reliable heating function
Solution Approach 2:
The heat trace cable is designed with multi-functional capabilities: it provides heating through resistive elements, self-mounting through integrated clips or adhesion features, and electrical connection through built-in terminals. This universal design allows a single component to perform multiple functions that previously required separate parts, reducing installation complexity and time
2Loss of time
If prefabricated heat-traced pipes are custom-made, then replacement time is reduced, but inventory space and manufacturing costs increase
Solution Approach 1:
The patent segments the heating system into modular heat trace cable units that can be produced as standardized components. These modular segments can be manufactured in advance and stored in inventory, then quickly assembled onto conduits or pipes as needed. This segmentation allows for standardization of manufacturing processes, reducing costs while enabling rapid replacement through pre-fabricated modules
Solution Approach 2:
The heat trace cable assemblies are designed to be pre-assembled with all necessary components (heating elements, mounting features, electrical connections) before field installation. This preliminary preparation of complete assemblies eliminates the need for custom fabrication during replacement operations, allowing standard inventory items to be quickly deployed while reducing both manufacturing complexity and on-site installation time
