Universal Wiper Adapter with Cylindrical Rod Cowling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current windscreen wiper adapters are not universal and require multiple varieties to accommodate different types of end pieces, making them impractical and uneconomical.
Innovation Solution
A universal adapter design featuring a longitudinal body with parallel lateral walls and a cowling that can accommodate cylindrical rods, allowing it to connect wiper blades to various end pieces, including those with U-shaped sections, through a single configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple varieties of adapters are produced to accommodate different types of end pieces, then compatibility with various end pieces is improved, but device complexity and production costs increase
Solution Approach 1:
The adapter body is designed with a universal structure featuring a longitudinal cavity that can accommodate different types of end pieces including U-shaped sections and laterally locking types. The cowling with transverse orifice receives cylindrical rods from various end piece configurations, allowing a single adapter design to interface with multiple end piece varieties without requiring multiple specialized adapters.
2Adaptability or versatility
If multiple varieties of adapters are produced to accommodate different types of end pieces, then compatibility with various end pieces is improved, but manufacturing costs increase
Solution Approach 1:
The adapter design consolidates multiple functions into a single component. The longitudinal body with its cavity structure and the cowling with transverse orifice create a universal interface that accommodates U-shaped end pieces, laterally locking end pieces, and other configurations, thereby eliminating the need to manufacture and inventory multiple specialized adapter varieties.
3Device complexity
If a universal adapter design is implemented to accommodate multiple end piece types, then the number of adapter varieties is reduced, but adaptability may be compromised
Solution Approach 1:
The adapter is divided into functional segments: the longitudinal body with cavity for receiving end piece variants, the connection means for the blade, and the cowling with transverse orifice for cylindrical rods. This segmentation allows each component to be optimized for its specific function while the overall structure maintains universality.
Solution Approach 2:
The adapter acts as an intermediary component between the wiper blade and various end piece types. The longitudinal cavity and transverse orifice serve as mediating structures that accommodate different geometries, allowing the blade connection system to interface with diverse end piece configurations through a single standardized adapter design.
