Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cover opening devices for cigarette cases, primarily relying on button switches and rotating springs, lack durability and do not provide a satisfying sliding mechanism for opening, which can be cumbersome and less user-friendly compared to sliding-cover devices used in other applications.
Innovation Solution
A sliding cover-opening device featuring a top support with sliding grooves, a cylindrical spring cap, a cover pushing spring, and a rotatable pushing cover with a rotating torsional spring, allowing for a 90-degree automatic rotation and enhanced durability through a sliding-resistant mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a button switch and rotating spring mechanism is used for cover opening, then the device structure is simple, but the durability is poor and user experience is unsatisfying
Solution Approach 1:
The cover opening device is segmented into multiple functional components: a button switch assembly, a rotating spring mechanism, and a sliding-resistant device with cylindrical spring cap. This segmentation allows each component to perform its specific function independently, improving overall durability while maintaining reasonable structural complexity
Solution Approach 2:
The device incorporates dynamic elements including a rotating spring that can twist and store energy, and a sliding-resistant device that allows controlled movement. These dynamic components enhance the durability and user experience by providing smooth, reliable operation over extended use periods
2Ease of operation
If a traditional button switch mechanism is used, then the device structure is simple, but the sliding mechanism is lacking and operation is cumbersome
Solution Approach 1:
The invention merges the button switch function with a sliding-resistant mechanism. The button switch is integrated with a cylindrical spring cap that slides within the top support, combining two functions into one unified structure. This provides a smooth sliding action that enhances ease of operation
Solution Approach 2:
The cylindrical spring cap acts as an intermediary element between the button switch and the cover. It provides a sliding surface that mediates the force application, making the opening action smoother and more user-friendly while adding controlled complexity to the mechanism
3Adaptability or versatility
If the cover rotation angle is limited, then the device structure is simple, but the rotation angle is not maximized and functionality is reduced
Solution Approach 1:
The rotating spring is pre-loaded in a compressed state when the cover is closed. This preliminary action stores energy that is released during opening, enabling the cover to rotate through a larger angle (up to 90 degrees or more) without requiring additional complex mechanisms during operation
