Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional wiper blade packing cases require complex and costly manufacturing processes, result in large packing volumes, and are prone to space inefficiencies during transportation and storage due to separate inner and outer containers that can easily shift during transit.

Innovation Solution

A wiper blade packing case design featuring a plate-shaped lower and upper panel with elliptical cross-sections, covered by elliptical covers with engaging protrusions and slots, and an assistant cover to securely encase the wiper blade, reducing material usage and simplifying assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate inner and outer packing containers are used, then the wiper blade is securely protected, but the packing volume increases and transportation space efficiency decreases

Engineering Contradiction:

Improveprotection of wiper bladeVSAvoidpacking volume

Core Design Contradiction:

ReliabilityVSVolume of stationary object

Solution Approach 1:

The patent merges the inner packing container and outer case into a single integrated packing case structure. The single packing case incorporates both protective functions while eliminating the need for separate containers, thereby reducing packing volume and improving space efficiency during transportation and storage.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The wiper blade is nested within the packing case structure, with the blade holder positioned inside the case body. This nesting arrangement ensures secure protection of the wiper blade while minimizing the overall packing volume by utilizing the internal space efficiently.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Reliability

If separate inner and outer packing containers are used, then the wiper blade is securely protected, but the manufacturing processes and material usage increase

Engineering Contradiction:

Improveprotection of wiper bladeVSAvoidmanufacturing processes

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple manufacturing processes into a single integrated structure. Instead of separately manufacturing inner containers and outer cases, the single packing case is manufactured as one unit, simplifying the manufacturing process and reducing the number of assembly steps required.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

While the overall structure is integrated, the packing case is segmented into functional portions (case body, blade holder, cover) that can be manufactured separately and then assembled. This segmentation allows for efficient manufacturing of individual components while still achieving the benefit of an integrated final product.

Inventive Principle:

Principle #1Segmentation

3Reliability

If conventional packing case structure is used, then the wiper blade is protected, but the exhibit space increases

Engineering Contradiction:

Improveprotection of wiper bladeVSAvoidexhibit space

Core Design Contradiction:

ReliabilityVSArea of stationary object

Solution Approach 1:

The patent merges the protective packaging function with the product display function into a single integrated structure. The transparent or openable cover design allows the wiper blade to be exhibited while remaining protected, eliminating the need for additional display space or separate packaging layers.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The packing case utilizes a sleek, compact shell design that provides protection while maintaining a space-efficient profile. The thin-walled construction reduces the overall footprint of the packing case, thereby decreasing the exhibit space required.

Inventive Principle:

Principle #30Flexible shells and thin films

4Adaptability or versatility

If inner packing container and outer case are separately manufactured, then manufacturing flexibility is maintained, but the manufacture cost increases

Engineering Contradiction:

Improvemanufacturing flexibilityVSAvoidmanufacture cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent combines multiple manufacturing operations into a single molding or fabrication process for the integrated packing case. This merging reduces the total manufacturing cost by eliminating separate material purchases, multiple manufacturing setups, and additional assembly labor, while still maintaining design flexibility.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The single packing case structure serves multiple functions (protection, display, storage, transportation) simultaneously, making it a universal solution that replaces multiple separate components. This multi-functionality reduces the overall cost by consolidating what would otherwise require multiple specialized parts.

Inventive Principle:

Principle #6Universality (Multi-functionality)
