Wiper Blade Heating Element Vertebra Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing windscreen wiper blade heating devices often expose electrical connectors to excessive heat, risking damage and reducing their lifespan due to direct heat radiation, especially when used frequently.
Innovation Solution
The heating element is positioned on the lower face of the vertebra, with electrical conduction means passing through crossings in the vertebra, which are strategically located to avoid direct heat exposure and ensure connectivity to the electrical connector, while maintaining effective heat distribution to the wiper blade.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the heating element is positioned on the upper face of the vertebra, then heat distribution to the wiper blade is improved, but the electrical connector is exposed to excessive heat which reduces its lifespan
Solution Approach 1:
The heating element is repositioned from the upper face to the lower face of the vertebra, utilizing the third dimension (vertical positioning) to resolve the contradiction. This spatial reconfiguration allows heat to be distributed effectively to the wiper blade while the vertebra structure itself shields the electrical connector from direct heat exposure, thus extending connector lifespan
2Reliability
If the heating element is positioned on the lower face of the vertebra, then the electrical connector is protected from heat, but the heat distribution efficiency to the wiper blade may be reduced
Solution Approach 1:
The vertebra acts as an intermediary structure that facilitates heat transfer from the heating element on its lower face to the wiper blade above. The vertebra's material properties and geometric structure enable it to conduct and distribute heat effectively while simultaneously serving as a thermal barrier that protects the electrical connector from excessive heat exposure

AI summary
The heating device is adapted to be assembled to a support element (3) of a wiper blade and includes a longitudinal main axis element (4) adapted to be mounted inside a housing (5) of the support element (3) so as to form a vertebra. A heating element (13) is disposed on an underside face of the vertebra-forming element (4). The vertebra-forming element (4) includes at least one through-hole (20) for the passage of electrical conduction means (19) for supplying power to the heating element (13).
