Solution Overview

Problem

Existing wiper blade packaging devices are inefficient in terms of component usage, weight, assembly effort, and manufacturing costs while maintaining stability, particularly in open storage configurations where less than 90% of the wiper blade's longitudinal extent is radially enclosed.

Innovation Solution

The wiper blade packaging device incorporates a support body with a counter-abutment surface and connecting elements, such as retaining clips, which couple the bearing surfaces to absorb forces, and a wiper lip receiving body formed as an elongated groove-forming rail, allowing for secure mounting and reduced material usage by being radially incompletely enclosed and featuring varying wall thicknesses.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a wiper blade packaging device uses traditional enclosed storage structure, then the wiper blade is well protected, but the device complexity and manufacturing costs increase

Engineering Contradiction:
Improvewiper blade protectionVSAvoidstorage structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The packaging device is divided into a wiper lip receiving body and a separate support body that couples together. This segmentation allows each component to be optimized independently, reducing overall complexity while maintaining protection functionality through the modular assembly approach.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The support body serves multiple functions: it provides structural support, couples the wiper lip receiving body to the mounting surface, and enables open storage configuration. This multi-functionality reduces the need for additional components, simplifying the overall device structure.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If the wiper lip receiving body is completely radially enclosed, then the wiper blade is securely protected, but the weight and material usage increase

Engineering Contradiction:
Improvewiper blade securityVSAvoidpackaging device weight
Core Design Contradiction:
ReliabilityVSWeight of stationary object

Solution Approach 1:

The invention extracts the essential protective function from the complete enclosed structure and implements it through a selective open storage design. The wiper lip receiving body is radially incompletely enclosed, removing unnecessary material while the support body provides the critical securing function through its coupling mechanism.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of uniformly enclosing the entire wiper blade, the design provides localized protection where needed - the wiper lip receiving body encloses the wiper lip area while leaving other areas open. This local quality approach reduces material usage and weight while maintaining security for the critical wiper lip component.

Inventive Principle:
Principle #3Local quality

3Adaptability or versatility

If multiple separate components are used for mounting, then the assembly is more flexible, but the assembly effort and manufacturing costs increase

Engineering Contradiction:
Improvemounting flexibilityVSAvoidassembly effort
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The support body and wiper lip receiving body are designed to couple together as an integrated assembly unit. This merging reduces the number of separate components that need to be handled during assembly, simplifying the manufacturing process while maintaining the flexibility to mount on various surfaces through the coupling mechanism.

Inventive Principle:
Principle #5Merging (Combining)
