Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wiper is designed to fit specific vehicle specifications, then wiping performance is improved, but manufacturing complexity increases due to producing various wipers in small quantity
Solution Approach 1:
The wiper blade is designed with a universal adaptor mechanism that can accommodate multiple wiper arm types and vehicle specifications through a single standardized interface, eliminating the need to manufacture separate wiper models for different vehicles
2Reliability
If the wiper blade is made disposable and replaced regularly, then wiping performance is maintained, but production cost increases due to manufacturing various specifications
Solution Approach 1:
By standardizing the adaptor interface, the same wiper blade design can be produced in large quantities for multiple vehicle types, significantly improving production efficiency while maintaining the disposable replacement model
3Adaptability or versatility
If the wiper blade is made adjustable with rotatable body and connector, then adaptability to different windshield shapes is improved, but device complexity increases
Solution Approach 1:
The adaptor incorporates a rotatable body and hinge-connected connector that enable dynamic adjustment of the wiper blade angle and position, allowing the same basic structure to adapt to different windshield shapes and wiper arm types without increasing overall device complexity

AI summary
Wiper device is disclosed. a wiper device includes a wiper blade tightly contacted to a windshield and configured to wipe a foreign substance and an adaptor connecting the wiper blade to a wiper arm, wherein the adaptor includes a body rotatably connected to the wiper blade about an axle formed in a traverse direction of the wiper blade, and a connector extended in a lengthwise direction of the wiper blade and having one end that is connected to the wiper arm and the other end that is hinge-connected to the body. Since it is possible to adjust the wiper arm and the wiper blade in various angles, the wiper blade can be tightly contacted to the windshield and thus have a superior wiping performance.
