Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiant heaters are inefficient in heating large areas and lack stability, with manual ash removal being hazardous due to hot ash and embers, and they often require complex handling and electrical connections.
Innovation Solution
A mobile radiant heater design with a burner unit and conveyor system where the solid fuel tank is located below the burner for stability, featuring a detachable burner unit for easy ash removal, air supply for efficient combustion, and a power supply unit for cordless operation, including a foot unit for support and cable management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the solid fuel tank is located below the burner unit, then the stability of the radiant heater is improved, but the device complexity increases due to the need for a conveyor system
Solution Approach 1:
The radiant heater is divided into separate functional modules: a solid fuel tank, a conveyor unit, a burner unit, and a control unit. This segmentation allows the fuel tank to be positioned low for stability while the conveyor system automatically manages fuel delivery, resolving the contradiction between stability and device complexity.
Solution Approach 2:
The conveyor unit automatically conveys solid fuel from the tank to the burner unit without manual intervention. The control unit manages the conveyor operation, creating a self-service system that eliminates the need for complex manual fuel handling while maintaining stable operation.
2Ease of operation
If the burner unit is detachably fastened in the housing, then the ease of operation for ash removal is improved, but the reliability of the connection decreases
Solution Approach 1:
The burner unit features a dynamic connection system with detachable fastening elements that can be easily engaged and disengaged. This allows the burner to be removed for ash removal while maintaining a reliable connection during operation, resolving the contradiction between ease of operation and reliability.
3Adaptability or versatility
If the radiant heater is designed for manual transport, then the adaptability increases for mobile use, but the weight becomes a limiting factor for heating large areas
Solution Approach 1:
The radiant heater employs a transparent radiant unit that radiates heat in multiple directions (360 degrees) rather than in a single direction. This dimensional change in heat distribution allows the lighter, mobile heater to effectively heat larger areas by utilizing spatial radiation patterns, resolving the contradiction between portability and heating capacity.
