Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the misting fan is connected to a small battery pack, then the portability and ease of operation are improved, but the power output and battery life are insufficient for large-scale applications

Engineering Contradiction:
ImproveportabilityVSAvoidpower output
Core Design Contradiction:
Ease of operationVSPower

Solution Approach 1:

The power supply system is segmented into multiple battery packs that can be independently connected in series or parallel configurations. This allows the system to be scaled from small portable units to large high-power applications by simply adding or reconfiguring battery modules, resolving the contradiction between portability and power output.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The battery configuration is made dynamic and adjustable, allowing users to change the electrical connection mode (series/parallel) based on operational needs. This enables the same physical battery packs to provide different power levels and voltage outputs, adapting to both portable and large-scale applications.

Inventive Principle:
Principle #15Dynamics

2Area of stationary object

If the misting fan is designed for large-scale high flow rate applications, then the cooling coverage area is improved, but the battery life and power consumption become problematic

Engineering Contradiction:
Improvecooling coverage areaVSAvoidbattery life
Core Design Contradiction:
Area of stationary objectVSDuration of action of moving object

Solution Approach 1:

The misting fan operates in periodic cycles with adjustable duty ratios, alternating between high-power misting mode and lower-power fan-only mode. This periodic operation reduces average power consumption while maintaining effective cooling coverage, thereby extending battery life for large-scale applications.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system dynamically changes operational parameters including misting intensity, fan speed, and duty cycle based on detected environmental conditions and power availability. This allows optimization of the balance between cooling coverage area and battery consumption duration.

Inventive Principle:
Principle #35Parameter changes

3Power

If the misting fan uses commercial power, then the power output and continuous operation capability are improved, but the adaptability to remote locations without sockets is reduced

Engineering Contradiction:
Improvepower outputVSAvoidadaptability to remote locations
Core Design Contradiction:
PowerVSAdaptability or versatility

Solution Approach 1:

The misting fan is designed with universal power supply capability, accepting both commercial AC power and DC battery pack inputs. The system can automatically or manually switch between power sources, making it universally adaptable to both fixed installations with electrical outlets and remote locations requiring portable battery operation.

Inventive Principle:
Principle #6Universality (Multi-functionality)
