Gas Infrared Heater with Multi-Level Radiant Heat Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current gas infrared heaters lack flexibility in heat settings, leading to uneven heating and inefficiency, as they typically have only one heat level setting, requiring multiple units for different areas and failing to adjust heat output to match environmental needs, and do not protect the operating system from heat after usage.
Innovation Solution
A gas infrared heater with multiple heat level settings, utilizing ceramic plaques with raised surfaces and a dual-stage control valve, where all plaques are active at all times, and a separate operating system compartment with insulation and a flue kicker to prevent heat exposure, allowing operation with natural gas or liquid propane and powered by battery or standard outlet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple heaters are used for different heat levels, then heat flexibility is improved, but device complexity and space requirements increase
Solution Approach 1:
The heater is divided into multiple independent burner assemblies (first burner assembly with first plaque, second burner assembly with second plaque, etc.), each capable of independent operation. This segmentation allows selective activation of individual burners to achieve different heat levels within a single heater unit, eliminating the need for multiple separate heaters.
Solution Approach 2:
The heater incorporates a control system that dynamically adjusts which burners are active based on heating requirements. The system can transition between different operational states (all burners off, one burner on, multiple burners on, all burners on) providing flexible heat level adjustment without requiring multiple fixed-capacity heater units.
2Adaptability or versatility
If burner selection system is used to control heat levels, then heat output flexibility is improved, but heating uniformity deteriorates
Solution Approach 1:
The heating system is segmented into multiple independent burner-plaque assemblies arranged in a sequence. Each assembly can be independently controlled, allowing the system to maintain uniform heating by selecting appropriate combinations of burners rather than partially activating a single large burner, thereby preserving heating uniformity while achieving heat level flexibility.
3Device complexity
If operating system compartment is exposed to burner heat, then device simplicity is improved, but component reliability deteriorates
Solution Approach 1:
The heater is divided into distinct functional compartments: a burner compartment housing the burner assemblies and plaques, and a separate operating system compartment housing electronic controls and power supply. This segmentation physically isolates heat-generating components from heat-sensitive components, protecting reliability while maintaining structural simplicity.
Solution Approach 2:
A heat shield or thermal barrier is positioned between the burner compartment and the operating system compartment, acting as an intermediary that blocks or reduces heat transfer to sensitive components. This allows the operating system to remain protected without requiring complete isolation or complex cooling systems.

AI summary
An indoor-outdoor gas infrared heater having one or more heat level settings. The heater includes a burner having ceramic plaques with a plurality of perforations and raised surfaces tapering into an apex between the perforations and an operating system having a control module electrically connected to a control valve, a power source and an activator for triggering the heater. The control valve has multiple pathways with each pathway supplying gas to the burner at a flow rate for a designated heat level setting. The heater has compartments for protecting the components from the heat coming from the burner.
