Solution Overview

Problem

Conventional heaters have complex and inefficient manufacturing processes due to individually manufactured and assembled components, leading to product quality and stability issues.

Innovation Solution

An integrated air heating and blowing arrangement where a fan assembly and a Positive Temperature Coefficient (PTC) heating apparatus are coupled to form a detachable structure within an outer casing, simplifying the manufacturing process and enhancing product quality and stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional heaters use individually manufactured and assembled components, then each component can be produced by specialized manufacturers, but the manufacturing process becomes complicated and product quality stability deteriorates

Engineering Contradiction:
Improvecomponent specializationVSAvoidmanufacturing process complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the fan assembly and heating apparatus into a single integrated structure that is pre-assembled as one unit. This merging of components resolves the contradiction by maintaining component specialization (each part can still be manufactured separately and then pre-assembled) while eliminating the complexity of final assembly at the heater manufacturing stage, thereby improving product quality stability.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of manufacture

If conventional heaters use individually assembled components, then manufacturing flexibility is maintained, but assembly efficiency and product quality stability worsen

Engineering Contradiction:
Improvemanufacturing flexibilityVSAvoidproduct quality stability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The fan assembly and heating apparatus are pre-assembled into an integrated structure before being installed in the heater. This preliminary assembly action allows manufacturers to maintain flexibility in producing different components separately, while ensuring consistent assembly quality through controlled pre-assembly processes, thereby improving product quality stability without sacrificing manufacturing flexibility.

Inventive Principle:
Principle #10Preliminary action

3Ease of repair

If components are individually mounted in the outer casing, then each component can be independently replaced, but the assembly process becomes time-consuming and costly

Engineering Contradiction:
Improvecomponent replaceabilityVSAvoidassembly efficiency
Core Design Contradiction:
Ease of repairVSProductivity

Solution Approach 1:

The integrated structure of the fan assembly and heating apparatus is designed as a detachable module that can be easily removed and replaced as a single unit. This segmentation approach maintains ease of repair (the entire heating module can be quickly replaced) while dramatically improving assembly efficiency (pre-assembled modules are installed as one unit rather than individual components), resolving the contradiction between replaceability and assembly speed.

Inventive Principle:
Principle #1Segmentation

AI summary

A heater includes an outer casing having an air inlet, an air outlet, and a receiving cavity defined between the air inlet and the air outlet, and an integrated air heating and blowing arrangement. The integrated air heating and blowing arrangement includes a fan assembly mounted in the receiving cavity for drawing air from ambient environment to pass through the air inlet and the air outlet, and a heating apparatus arranged to heat up the air drawn by the fan assembly. The heating apparatus is coupled with the fan assembly to form an integrated structure for being detachably mounted in the receiving cavity of the outer casing.
