Dispenser Lid Biasing Pin Mechanism for Flexible Sheet Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible sheet containers require a design that balances easy access to stored sheets with a compact and aesthetically pleasing appearance, while ensuring convenient dispensing of flexible sheets, particularly in portable and household settings.
Innovation Solution
A container design featuring a primary lid with a pivotally attached dispenser lid and a biasing pin mechanism that urges the dispenser lid towards an open position, allowing easy access while maintaining a compact form when closed, utilizing a flexible biasing pin anchored on both the dispenser and primary lids to facilitate effortless sheet dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a dispenser lid is added to provide easy access to flexible sheets, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The lid is divided into two functional segments: a primary lid that closes the storage cavity and a dispenser lid that provides access to flexible sheets. This segmentation allows each lid to perform its specific function independently, improving ease of operation while maintaining manageable structural complexity through modular design
Solution Approach 2:
The dispenser lid is nested within or integrated with the primary lid structure, allowing the smaller dispenser lid to be part of the larger lid assembly. This nesting approach provides easy access functionality while avoiding the need for completely separate components, thus controlling overall device complexity
2Ease of operation
If a biasing pin mechanism is added to urge the dispenser lid towards the open position, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The biasing pin mechanism provides self-service by automatically urging the dispenser lid towards the open position without requiring user intervention. The mechanical biasing force operates autonomously to assist lid opening, improving ease of operation while maintaining relatively simple mechanism complexity through passive mechanical action
Solution Approach 2:
The biasing pin replaces more complex actuation mechanisms (such as springs, motors, or cam systems) with a simpler mechanical biasing element. This substitution achieves effortless lid opening while minimizing the complexity of the overall mechanical system through a straightforward pinned connection
3Volume of moving object
If the container is designed to be compact for storage, then volume is reduced, but ease of access to dispenser opening is worsened
Solution Approach 1:
The lid system is segmented into a primary lid for overall closure and a smaller integrated dispenser lid for sheet access. This segmentation allows the container to maintain a compact form while providing a dedicated, easily accessible dispenser opening that does not require opening the entire primary lid
Solution Approach 2:
The dispenser lid provides localized access functionality at the specific location where sheets need to be dispensed. This local quality approach allows the majority of the container to remain compact while creating a focused access point that is optimally positioned and sized for its specific function
