Fastening structure for electric heating panels of electric heater, and electric heater
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electric heating plate fixing structures for electric heaters require complex assembly processes, high labor costs, and inefficient wire fixation methods, often necessitating multiple operators and leading to potential wire damage due to sheet metal burrs.
Innovation Solution
A simplified electric heating plate fixing structure that omits ceramic base assemblies, using a cross beam, outer support, and first support with snap-fit or threaded connections, along with insulating structures, to facilitate easy assembly and efficient wire management, reducing labor costs and preventing wire damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ceramic base assemblies and bolt assemblies are used to fix electric heating plates, then the heating plates can be securely fixed, but the assembly process becomes complex and labor-intensive
Solution Approach 1:
The patent combines the ceramic base assembly and bolt assembly into an integrated fixing structure where the ceramic base is directly mounted on the cross beam with built-in positioning and fixing features, eliminating the need for separate bolt assemblies and reducing the total number of parts
Solution Approach 2:
The patent extracts and eliminates unnecessary intermediate components from the fixing system, removing the bolt assembly entirely and using a simplified ceramic base design that directly engages with the cross beam through integrated positioning holes and fixing mechanisms
2Reliability
If multiple ceramic base assemblies and bolt assemblies are used for each heating plate, then secure fixing is achieved, but the number of parts increases and assembly efficiency decreases
Solution Approach 1:
The patent merges multiple fixing functions into a single integrated ceramic base assembly that includes positioning holes, mounting features, and fixing mechanisms, reducing the part count from multiple ceramic bases and bolts to a simplified integrated component
Solution Approach 2:
The ceramic base assembly is pre-assembled with positioning holes and fixing features before installation, allowing for quick alignment and attachment to the cross beam without requiring complex on-site assembly operations
3Reliability
If wires are fixed by buckles of the lower cross beam, then wire fixation is achieved, but the wire fixing method becomes complex and creates hidden troubles of sheet metal burrs scratching the wire
Solution Approach 1:
The patent introduces a plastic support as an intermediary component between the wire and the metal cross beam, which provides a burr-free surface for wire attachment and eliminates direct contact between wires and sharp metal edges
Solution Approach 2:
The patent uses a simple plastic support structure that is easy to manufacture and replace, providing a cost-effective solution to protect wires from damage by sheet metal burrs without requiring complex protective mechanisms
