Wiper Blade Spray Channel Heating Loop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiper blade systems face challenges in simplified electrical contacting and efficient heating of spray channels and supply lines to prevent icing and enhance cleaning effectiveness.
Innovation Solution
The wiper blade integrates a heating element in the form of a heating loop within the spray channel, which extends along the longitudinal side of the wiper blade, allowing direct heating of the washing liquid and supply lines, with optional additional heating sections for the supply lines, and automatic control based on environmental and operational parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a heating element is integrated into the spray channel of the wiper blade, then the heating effectiveness and cleaning performance are improved, but the device complexity and constructive effort increase
Solution Approach 1:
The heating element is integrated directly into the spray channel structure of the wiper blade, merging the heating function with the existing spray channel. This combination eliminates the need for separate heating components and reduces constructive effort while maintaining heating effectiveness.
Solution Approach 2:
The spray channel structure is designed to serve dual purposes: as a fluid conduit for washing liquid and as a housing for the heating element. This multi-functionality reduces the number of separate components needed, simplifying the overall device structure.
2Temperature
If the heating element is placed inside the spray channel, then direct heating of washing liquid is achieved, but the electrical contacting becomes more complex
Solution Approach 1:
The electrical connection points of the heating element are extracted and positioned at accessible locations on the wiper blade body, separate from the internal spray channel. This allows for simplified electrical contacting while the heating element remains positioned for optimal heating of the washing liquid.
Solution Approach 2:
Electrical connection elements are introduced as intermediaries between the power source and the heating element inside the spray channel. These intermediaries facilitate electrical contact while allowing the heating element to remain positioned for direct heating effectiveness.
3Reliability
If additional heating sections are added for supply lines, then icing prevention is improved, but the device complexity increases
Solution Approach 1:
The heating system is segmented into distinct heating sections: one integrated into the spray channel for direct heating of washing liquid, and additional heating sections integrated into the supply lines for icing prevention. This segmentation allows targeted heating where needed without requiring a single complex heating system.
Solution Approach 2:
The heating elements for the supply lines are integrated directly into the supply line structure, merging the heating function with the fluid conduit. This integration prevents icing of the supply lines without requiring separate external heating components.
