Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing helmets with electrically heated visors for preventing condensation do not allow users to control the amount of heat generated, leading to inefficient power usage and discomfort due to constant power supply.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If an electrically heated visor is used to prevent condensation, then condensation is eliminated, but power consumption increases and cannot be controlled
Solution Approach 1:
The patent applies dynamics by making the heating element controllable through multiple switches that allow the user to select different power levels (first, second, and third positions). This transforms the static, constant-power heating system into a dynamic, adjustable system where power consumption can be optimized based on actual condensation conditions, resolving the contradiction between effective condensation prevention and excessive power usage.
Solution Approach 2:
The patent changes the electrical parameter (power level) of the heating element by providing multiple selectable positions through switches. The controller can select from different power levels delivered to the heating element, allowing the system to adapt power consumption to actual needs while maintaining effective condensation prevention when required.
2Reliability
If constant electrical power is supplied to the heating element, then condensation is consistently prevented, but power source is drained even when heating is not needed
Solution Approach 1:
The patent applies partial action by allowing the user to select from different power levels (first, second, third positions) rather than always using maximum power. The controller can deliver partial power (second position) or reduced power (third position) when full heating is not required, reducing energy loss while still maintaining sufficient heating to prevent condensation under varying conditions.
Solution Approach 2:
The patent enables periodic adjustment of power levels through controllable switches that allow the user to change heating intensity based on varying environmental conditions. The system can alternate between different power levels or turn heating off when not needed, rather than maintaining constant power supply, thus reducing overall energy consumption while maintaining reliability when required.
3Object-affected harmful factors
If the visor is heated continuously, then condensation is prevented, but user comfort decreases due to excessive heat
Solution Approach 1:
The patent applies dynamics by providing multiple controllable positions for the heating element power levels. Users can adjust the heating intensity to match actual environmental conditions, selecting lower power levels when mild heating suffices for condensation prevention, thereby maintaining user comfort while still preventing condensation effectively.
4Device complexity
If a simple heating element is used, then the device is simple, but the user cannot control the heat output
Solution Approach 1:
The patent applies multi-functionality by integrating multiple switches and a controller that can select from different power levels within a single heating system. This allows the basic heating element to perform multiple functions at different intensity levels, providing user control and adaptability without requiring separate heating devices for different conditions.
