Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dispensers lack a simple and interchangeable locking mechanism that can switch between a push button and a key operation, often requiring complex solutions and interchangeable parts, which complicates dual-use locking functionality.
Innovation Solution
A locking assembly that includes a locking component and a barrel capable of rotating between two positions, allowing for either key or push button operation, enabling easy switching between locking methods without the need for complex mechanical solutions or interchangeable parts, utilizing a simple mechanical design with reduced operating parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional dispensers use a locking mechanism that switches between push button and key operation, then the locking functionality is secure and reliable, but the device complexity increases due to requiring interchangeable parts and complex mechanical solutions
Solution Approach 1:
The patent combines the push button mechanism and key operation into a single integrated locking assembly. The barrel serves dual purposes: it acts as a push button when pressed directly, and as a key receptacle when a key is inserted. This merging eliminates the need for separate locking mechanisms and interchangeable parts, reducing device complexity while maintaining secure locking functionality through a unified mechanical design
Solution Approach 2:
The locking assembly is designed with multi-functionality where the barrel can operate in two modes: as a push button for simple access and as a key-operated lock for secure access. The same mechanical components serve multiple functions, allowing the system to adapt to different security requirements without requiring separate mechanisms, thereby reducing overall device complexity while maintaining reliability
2Adaptability or versatility
If conventional dispensers use interchangeable parts for dual-use locking, then the adaptability is improved, but the ease of manufacture decreases due to requiring multiple components
Solution Approach 1:
The patent merges the push button and key lock into a single integrated assembly where the barrel serves both functions. This eliminates the need for multiple interchangeable parts, simplifying manufacturing processes while maintaining the adaptability to provide either push button or key-operated locking. The unified design reduces component count and assembly steps, improving ease of manufacture
Solution Approach 2:
The locking assembly is designed as a universal mechanism that can perform both push button and key-operated functions using the same components. This multi-functionality is achieved through a single design that accommodates both operating modes, eliminating the need for separate parts and simplifying manufacturing while maintaining versatility in locking options
3Ease of manufacture
If a locking assembly uses a simple mechanical design with reduced operating parts, then the ease of manufacture is improved, but the reliability of locking may be compromised
Solution Approach 1:
The patent achieves reliable locking with a simple mechanical design by merging the push button and key lock functions into a single assembly. The barrel's dual functionality provides secure locking when a key is used, while the integrated spring mechanism ensures reliable engagement and disengagement. This unified design maintains reliability through proper mechanical engineering of the combined system while achieving ease of manufacture by eliminating interchangeable parts

AI summary
A locking assembly for a dispenser may include a locking component and a barrel. The locking component is movable between (i) a first position configured to lock a cover of the dispenser, and (ii) a second position configured to unlock the cover. The barrel is rotatable between (i) a first barrel position configured to resist movement of the locking component, and (ii) a second barrel position configured to permit movement of the locking component. The barrel defines a barrel opening configured to receive a key or a push button. A dispenser including a dispenser plate and a cover may further include the locking assembly. The dispenser defines an interior closable with the cover. The cover is movably coupled to the dispenser plate. The locking assembly releasably secures the cover to the dispenser plate.
