Solution Overview

Problem

Existing packaging for windshield wiper blades is non-environmentally friendly and lacks visibility of the wiper blade, often using non-biodegradable materials and complete enclosure which hinders inspection.

Innovation Solution

A packaging design featuring a box with a viewing opening and a transparent cellulose viewing window, supported by a cardboard frame, allowing partial visibility and biodegradability, with specific dimensions and stiffness to maintain structural integrity under spring bias forces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the box is made completely enclosed to protect the wiper blade, then the protection and structural integrity is improved, but the visibility of the wiper blade for inspection deteriorates

Engineering Contradiction:

Improveprotection of wiper bladeVSAvoidvisibility of wiper blade

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The box is segmented into enclosed sections and a transparent viewing window section, allowing most of the box to remain enclosed for protection while a specific segment provides visibility without compromising overall structural integrity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The box has different material properties in different locations: most of the box is made from opaque cardboard material for protection, while a specific local area (viewing window) is made from transparent cellulose material to provide visibility, allowing each region to serve its specific function optimally

Inventive Principle:

Principle #3Local quality

2Strength

If non-biodegradable materials are used for packaging durability, then the structural strength and longevity is improved, but the environmental friendliness deteriorates

Engineering Contradiction:

Improvepackaging durabilityVSAvoidenvironmental impact

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

The material is changed from conventional non-biodegradable plastics to biodegradable cellulose material, changing the chemical composition and degradation properties while maintaining the functional properties of transparency and structural support

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The packaging uses composite construction combining cardboard material for the box structure with transparent cellulose material for the viewing window, where both materials are biodegradable, creating an environmentally friendly composite packaging system that maintains structural integrity

Inventive Principle:

Principle #40Composite materials

3Stability of the object's composition

If the viewing window is made from thick rigid material for self-support, then the structural stability is improved, but the biodegradability and environmental friendliness deteriorates

Engineering Contradiction:

Improveviewing window stabilityVSAvoidbiodegradability

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The viewing window is extracted from the requirement to be self-supporting by relying on the box frame for structural support, allowing the viewing window material to be thin and flexible while still maintaining overall stability, thus enabling use of biodegradable cellulose material

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The box frame acts as an intermediary structural element that provides support to the viewing window, allowing the viewing window material itself to be thin and non-structural while the frame承担s the structural load, enabling use of biodegradable materials

Inventive Principle:

Principle #24Intermediary (Mediator)

4Loss of information

If the viewing opening is made large for better visibility, then the visibility of wiper blade is improved, but the stiffness and structural integrity of the box deteriorates

Engineering Contradiction:

Improvevisibility of wiper bladeVSAvoidbox stiffness

Core Design Contradiction:

Loss of informationVSStrength

Solution Approach 1:

Inventive Principle:

Principle #3Local quality

AI summary

A packaging for a wiper blade (10) and a windshield wiper includes a box (20) having at least one viewing opening (22), at least one viewing window (30), and an insert (30). The viewing window (30) is formed from an at least partially transparent cellulose material and closes the viewing opening (22) of the box (20). The box (20) is configured as a support frame for the viewing window (30). The insert (40) has external dimensions, which substantially correspond to an interior volume of the box (20) and the insert (40) is arranged to receive the wiper blade (10) with an internal shape corresponding to the wiper blade (10) and to be inserted into the box (20) together with the wiper blade (10).
