Wiper Blade Packaging Case with Integrated Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wiper blade packaging cases are prone to separation during delivery, leading to damage of the wiper blades and increased distribution costs due to inefficient design, which fails to securely hold the wiper blades and occupies excessive volume.
Innovation Solution
A packaging case with a body featuring securing protrusions and a cover with through-holes and elastic connecting parts, allowing the wiper blade to be maintained in an unfolded state, securely held by projections and clips, reducing contact with the inner surface and preventing damage, while being compact and easy to assemble.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional packaging cases use separate inner and outer cases, then the wiper blade can be packaged, but the packaging case is prone to separation during delivery and the inner case may escape from the outer case
Solution Approach 1:
The patent merges the inner case and outer case into a single integrated packaging case structure. The locking section with protrusions and recesses creates a unified design where the cover and body form one cohesive unit, eliminating the separation issues between inner and outer cases while maintaining protective functionality.
Solution Approach 2:
The packaging case is segmented into functional sections: a body with locking section, a cover with connecting parts, and an accommodating space. The locking section is further divided into protrusions on the body and corresponding recesses on the cover, creating modular components that work together to prevent separation while maintaining structural integrity.
2Object-affected harmful factors
If conventional packaging cases lack secure holding means, then the structure is simple, but the wiper blade is likely to experience scratching, peeling-off of paint, and damage during delivery
Solution Approach 1:
The packaging case applies local quality by creating specific securing zones within the accommodating space. The locking section with protrusions and recesses is strategically positioned to contact and secure the wiper blade at critical points, providing protection exactly where needed without requiring complex structures throughout the entire case.
Solution Approach 2:
The packaging case design incorporates preliminary action by pre-configuring the locking section with protrusions and recesses that automatically engage to secure the wiper blade in place. This pre-established securing mechanism prevents damage before delivery begins, rather than requiring additional securing steps during packaging.
3Adaptability or versatility
If the wiper blade is accommodated in a curved shape, then it corresponds to the windshield shape, but the packaging case occupies large volume and increases delivery costs
Solution Approach 1:
The packaging case utilizes dimensionality change by allowing the wiper blade to be accommodated in a flattened or compacted state within the accommodating space, rather than maintaining its full curved windshield shape. The locking section secures the blade in this compressed configuration, reducing volume while still allowing the blade to function on curved windshields when installed.

AI summary
Disclosed herein is a packaging case (60) of a wiper blade (50) used to wipe a windscreen of automobiles. The wiper blade includes a wiper strip (52) to wipe a windshield of an automobile. The packaging case comprises a body (70) having an accommodating space to accommodate the wiper blade (50) and an opening to open the accommodating space, a cover (80) connected pivotally to one side of the body (70) via a first connecting part (76) to cover the opening, and a locking section (90) connected pivotally to the other side of the body via a second connecting part (78) to be engaged with the body with one end of the cover interposed between the locking section and the body. The packaging case can protect the wiper blade from external force and prevent damage of the wiper blade during delivery and distribution, and can ensure simple, compact and tight packaging of the wiper blade.
