Wiper Standby Position Switching for Small Mobility Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wiping devices for small-sized mobility vehicles lack the ability to change the standby position of the wiper blade, limiting usability during maintenance and operation.
Innovation Solution
A wiping device with a drive part powered by a motor and an operation part, such as an automatic return type toggle switch, that outputs an operation signal to change the wiper blade's standby position based on specified operation times, allowing the wiper blade to switch between two predefined positions near the left and right ends of the windshield.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the standby position of the wiper blade is fixed in advance, then the device structure is simple, but the adaptability and usability are limited
Solution Approach 1:
The patent applies the dynamics principle by making the standby position of the wiper blade changeable rather than fixed. The control unit receives operation signals from the operation part and dynamically adjusts the standby position based on the number of operation times, allowing the system to adapt to different user needs while maintaining a relatively simple overall structure.
Solution Approach 2:
The patent implements parameter changes by varying the standby position parameter based on the count of operation signals. The control unit modifies the standby position parameter (first standby position or second standby position) according to the operation times, enabling flexible adaptation without requiring complex structural changes to the wiper mechanism itself.
2Ease of operation
If the standby position is fixed near the left or right end of the windshield, then the device is simple to operate, but it cannot meet maintenance requirements where position changes are needed
Solution Approach 1:
The system maintains ease of operation through a simple operation part (such as a switch or button) that the user can easily operate. The dynamics principle is applied in the control unit, which automatically determines the new standby position based on the operation signal count, eliminating the need for complex user adjustments while providing position change capability.
Solution Approach 2:
The control unit performs self-service by automatically determining and switching between standby positions based on the number of operation signals received. This eliminates the need for the user to manually configure or remember position settings, as the system autonomously manages the standby position changes based on simple user inputs.

AI summary
Provide is a wiping device that wipes off rainwater from a wiped surface by reciprocating a wiper blade by a power source. The wiping device includes a drive part that drives a power source; and an operation part that outputs an operation signal specifying a standby position of the wiper blade to the drive part.
