Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple specific wiper adapters are manufactured for different wiper arm types, then compatibility with various wiper arms is achieved, but manufacturing costs increase and resources are wasted

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSLoss of substance

Solution Approach 1:

The patent designs a universal wiper adapter base with multiple L-shaped structures that can accommodate different wiper arm types through a single standardized interface. The base includes receiving slots and positioning structures that work with various wiper arm configurations, eliminating the need for multiple specialized adapters for different car manufacturers.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple specific wiper adapters are manufactured for different wiper arm types, then compatibility with various wiper arms is achieved, but manufacturing costs increase

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If multiple specific wiper adapters are manufactured for different wiper arm types, then compatibility with various wiper arms is achieved, but environmental protection trends are not met

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Loss of substance

If a single universal wiper adapter is designed, then resource efficiency and environmental protection are improved, but compatibility with various wiper arm types may be compromised

Engineering Contradiction:

Core Design Contradiction:

Loss of substanceVSAdaptability or versatility

Solution Approach 1:

The adapter is divided into a base portion with universal compatibility features and a cover portion that can be configured for specific wiper types. The base includes standardized L-shaped structures and receiving slots, while the cover can be adjusted or replaced to match different wiper arm configurations, maintaining both universality and specificity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The adapter incorporates adjustable or interchangeable components that allow it to dynamically adapt to different wiper arm types. The positioning structures can be reconfigured or adjusted to accommodate various wiper geometries, enabling a single adapter design to serve multiple functions across different vehicle models.

Inventive Principle:

Principle #15Dynamics

AI summary

A wiper adapter includes a base and a shielding cover. The base has a top wall, a pair of side walls, and a pair of bottom walls. Two sides of the top wall respectively include a limiting wall extending upward. A width of the lateral L-shaped structure along a transverse direction is smaller than a width of one of the bottom walls along the transverse direction. The at least one lateral L-shaped structure is configured to stop a displacement of a wiper arm. Each bottom wall has at least one lower L-shaped structure that is configured to stop a displacement of another wiper arm. A receiving slot is formed between the shielding cover and the base, and is configured to receive yet another wiper arm. The shielding cover is connected to a front end of the pair of side walls to stop a displacement of the wiper arm.
