Sliding Hinged Blade Dispenser to Prevent Accidental Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blade dispensers with hinged chambers are prone to accidental opening, making blades accessible and posing safety risks.
Innovation Solution
A blade dispenser with a sliding structure that includes a body portion and a lid portion, where the lid is slidable relative to the body, and a hinge mechanism that allows the dispenser to transition between closed, extended, and open configurations, enabling secure storage and easy access to blades.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hinged chamber design is used for blade storage, then easy access to blades is achieved, but safety is compromised due to accidental opening
Solution Approach 1:
The dispenser is divided into three distinct segments: a body portion, a slidable lid portion, and a hinged chamber portion. This segmentation allows each component to perform its specific function - the lid provides secure closure, while the hinged chamber enables controlled access - thereby resolving the contradiction between safety and ease of access.
Solution Approach 2:
The mechanism transitions from a static hinged design to a dynamic two-stage system. The lid portion slides to extend the dispenser, and only then can the hinged chamber open. This dynamic sequence ensures that the chamber is only accessible when intentionally opened after the lid is moved, preventing accidental opening while maintaining easy access when needed.
2Object-affected harmful factors
If a sliding lid structure is added to prevent accidental opening, then safety is improved, but device complexity increases
Solution Approach 1:
The sliding lid mechanism and hinged chamber are merged into a coordinated system where the lid's extension motion naturally positions the chamber for opening. This integration means the safety feature (sliding lid) and access feature (hinged chamber) work together as a unified mechanism rather than separate complex systems, minimizing overall complexity while maintaining safety.
3Object-affected harmful factors
If the lid is kept closed to ensure safety, then blade accessibility is reduced, but safety is maintained
Solution Approach 1:
The user must first perform the preliminary action of sliding the lid portion to extend the dispenser before accessing the blades. This preliminary action serves as an intentional activation step that distinguishes deliberate access from accidental opening, thereby maintaining safety while enabling easy access when needed.

AI summary
The present invention provides a blade dispenser (10) which includes a body portion (20); and a lid portion (30) slidable relative to the body portion to move the blade dispenser between a closed configuration and an extended configuration. The lid portion comprises a first lid portion (110) having a first blade chamber (170) and a second lid portion (120) having a second blade chamber (180). The first lid portion and the second lid portion are coupled by a hinge portion (130) configured to permit the first lid portion to pivot relative to the second lid portion to move the blade dispenser from the extended configuration to an open configuration. In the open configuration blades may be removed from or inserted into both the first blade chamber and the second blade chamber.
