Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the wiper blade is designed to be inclined laterally with elasticity for ease of operation, then the ease of operation is improved, but the cleaning force deteriorates because the blade cannot maintain a right angle with the cleaning surface
Solution Approach 1:
The wiper blade is segmented into three functional parts: a mounting part, an angle maintaining bendable part with 4-link structure, and a contacting edge. This segmentation allows the mounting part to incline for ease of operation while the angle maintaining part ensures the contacting edge stays perpendicular to the cleaning surface for optimal cleaning force.
Solution Approach 2:
Different parts of the wiper blade have different functional qualities: the mounting part is designed for elastic inclination to facilitate operation, while the contacting edge is designed to maintain a fixed perpendicular angle for effective cleaning. The angle maintaining bendable part transitions between these two requirements.
2Force
If the wiper blade maintains a right angle with the cleaning surface for optimal cleaning force, then the cleaning force is improved, but the ease of operation deteriorates because the blade cannot incline laterally during movement
Solution Approach 1:
The wiper blade is segmented into three functional parts: a mounting part, an angle maintaining bendable part with 4-link structure, and a contacting edge. This segmentation allows the mounting part to incline for ease of operation while the angle maintaining part ensures the contacting edge stays perpendicular to the cleaning surface for optimal cleaning force.
Solution Approach 2:
The angle maintaining bendable part is designed to be dynamically adaptable: it allows lateral inclination of the mounting part during operation for ease of use, while simultaneously maintaining the perpendicular angle of the contacting edge for optimal cleaning force through its elastic material properties and 4-link structure.
3Ease of manufacture
If the wiper blade uses a simple structure for ease of manufacture, then the ease of manufacture is improved, but the ability to maintain angle and provide line contact deteriorates
Solution Approach 1:
The angle maintaining bendable part is made of elastic material that can be molded into a 4-link structure, combining manufacturing simplicity with functional precision. This flexible structure naturally maintains the perpendicular angle through its elastic properties while allowing lateral inclination during operation.
