Solution Overview
Problem
Existing outdoor gas heaters face challenges in convenience of use and safety, particularly with manual operation being inconvenient due to high switch placement and limited application scope when relying on AC power, which restricts their usage.
Innovation Solution
The design incorporates a rectangular hollow body box with four ceramic burners, a solenoid valve, signal processor, battery box, and remote control receiver, allowing for remote operation and energy-efficient long-term power supply, with a solenoid valve connected to a long open flame component for continuous ignition and automatic gas cutoff in case of flame loss, enhancing usability and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual operation is used with high-position switches, then installation is simple and safe, but ease of operation deteriorates
Solution Approach 1:
A remote control device is introduced as an intermediary between the user and the heater system. The remote control transmits signals wirelessly to the control box, enabling operation without direct physical contact with high-position switches. This resolves the contradiction by maintaining the simple installation structure while dramatically improving ease of operation through the intermediary remote control device.
2Ease of operation
If AC power supply is used, then ease of operation improves with remote control, but adaptability deteriorates due to limited application scope
Solution Approach 1:
The heater system is designed with dual power supply capability, incorporating both AC power input and battery power input. The control box can automatically or manually switch between power sources, making the device universally applicable in various environments. This resolves the contradiction by enabling remote control operation via AC power while also maintaining adaptability to locations without AC power through battery operation.
Solution Approach 2:
The power supply system is designed to be dynamic and adaptable, allowing the heater to switch between different power sources based on availability. The control circuitry can detect power source status and automatically adjust operation mode, enabling the same device to function optimally in both AC-powered and battery-powered environments, thus expanding application scope while maintaining ease of operation.
3Adaptability or versatility
If batteries are used for power supply, then adaptability improves for locations without AC power, but duration of action deteriorates due to limited battery life
Solution Approach 1:
The power supply system is designed to be dynamic and adaptable, allowing the heater to switch between different power sources based on availability. The control circuitry can detect power source status and automatically adjust operation mode, enabling the same device to function optimally in both AC-powered and battery-powered environments, thus expanding application scope while maintaining ease of operation.
4Ease of operation
If remote control receiver, signal processor, and solenoid valve are continuously powered, then ease of operation improves, but use of energy deteriorates
Solution Approach 1:
The control system employs periodic action by entering sleep mode after a period of inactivity. The microcontroller and related components are powered down or placed in low-power state after detecting no remote control signals for a predetermined time period. When a signal is received, the system activates and returns to normal operation. This periodic on-off cycling maintains full remote control functionality while dramatically reducing power consumption during idle periods.
Solution Approach 2:
The control system includes automatic power management that monitors its own power consumption and operational state. The microcontroller detects idle conditions and automatically transitions the system to sleep mode, then self-activates upon receiving remote control signals. This self-service power management maintains ease of operation while minimizing energy use without requiring manual intervention from the user.
