Pivoting Wiper Blade Packaging Case with Projection-Aperture Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional packaging cases for windshield wiper blades lack a secure and easy-to-close design, which can lead to damage and improper storage of the wiper blades.
Innovation Solution
A packaging case with an elongated wiper blade receiving section and a pivotally coupled cover section, featuring retaining elements and apertures/projections for secure closure, allowing the case to be easily opened and closed while maintaining the wiper blade's optimal state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional packaging cases are used for windshield wiper blades, then the structure is simple, but the closure is not secure and easy-to-close
Solution Approach 1:
The cover section is designed to pivot between open and closed states, providing dynamic movement for easy operation. The pivotable connection allows the cover to be easily opened and closed while the projection-aperture locking mechanism ensures secure closure when closed.
Solution Approach 2:
The projection-aperture mechanism automatically locks when the cover is closed, providing self-securing functionality. The retaining elements and apertures are positioned such that closure automatically engages the locking feature without requiring additional user action.
2Reliability
If conventional packaging cases are used for windshield wiper blades, then the design is simple, but the wiper blade may be damaged or improperly stored
Solution Approach 1:
The packaging case is divided into a base section and a separate cover section that pivots independently. This segmentation allows the cover to provide protective enclosure while maintaining a relatively simple overall structure through the use of a hinge connection rather than a complex locking mechanism.
Solution Approach 2:
The cover section fits over the base section in a nested arrangement, with the cover compartment enclosing the wiper blade receiving section. This nesting provides protection while using simple geometric forms without requiring complex structural elements.
3Ease of operation
If the cover section is pivotally coupled to the base section, then the case can be easily opened and closed, but the closure mechanism must be sufficiently secure
Solution Approach 1:
The pivotable connection enables dynamic opening and closing motion for ease of operation, while the projection-aperture locking feature provides static retention strength when closed. The system transitions from a purely dynamic hinge to a combined dynamic-static locking mechanism.
Solution Approach 2:
The invention merges the pivotable connection (for ease of operation) with the projection-aperture locking mechanism (for closure retention). These two features work together in a unified closure system that provides both easy opening/closing and secure retention.

AI summary
A packaging case for a windshield wiper blade includes an elongated wiper blade receiving section including a perimeter wall defining a blade-retaining channel. The perimeter wall includes inner and outer wall segments. At least one aperture is formed within the outer wall segment of the perimeter wall. An elongated cover section is pivotally coupled to wiper blade receiving section and configured to pivot between an open state and a closed state. The elongated cover section includes first and second lateral walls and first and second end walls defining a cover compartment that fits over the elongated wiper blade receiving section. At least one projection is formed on an inner surface of the first lateral wall for engaging the at least one aperture formed within the outer wall segment of the contoured wall, thereby retaining the cover section over the wiper blade receiving section.
