Solution Overview

Problem

The exposure of wiper blades on vehicles leads to aesthetic degradation, excessive wind noise, and aerodynamic performance issues due to their mounting location.

Innovation Solution

A wiper covering system with a movable wiper cover and a drive mechanism using a link structure, which can be stored inside the hood and extended to cover the wiper blades, minimizing exposure and incorporating a washer fluid nozzle and hose for efficient operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If the wiper blade is mounted exposed outside the vehicle to satisfy wiping area regulations, then the wiping coverage is maximized, but the aesthetic appearance deteriorates and wind noise increases

Engineering Contradiction:

Improvewiping areaVSAvoidwind noise and aesthetic degradation

Core Design Contradiction:

Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The wiper blade is extracted from its conventional exposed position and relocated to a hidden position within the hood cavity. The blade can be deployed when needed and retracted when not in use, separating the wiping function from the visible exterior area, thus eliminating the aesthetic and wind noise problems while preserving the wiping capability.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The wiper blade is transformed from a static exposed component to a dynamic movable component that can change position between hidden (stored in hood) and visible (deployed on windshield) states. This dynamic positioning allows the system to optimize both aesthetics (when hidden) and functionality (when deployed).

Inventive Principle:

Principle #15Dynamics

2Stability of the object's composition

If the wiper blade mounting location is constrained by windshield and hood mounting conditions, then the structural integration is improved, but the wiper blade exposure and resulting wind noise increase

Engineering Contradiction:

Improvestructural integrationVSAvoidwind noise

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The wiper blade storage location is moved from the traditional side-mounted or front-mounted position to a previously underutilized space dimension - the hood cavity. This spatial reconfiguration allows the blade to be integrated into the vehicle structure while remaining hidden from the exterior, resolving the conflict between structural integration and wind noise reduction.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
