Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing closure devices, such as buttons and diskettes, face limitations in practicality and security due to the need for rotation to achieve a secure seal, and they lack versatility for easy part interchangeability and multiple anchoring points, making them inconvenient for domestic and industrial use.
Innovation Solution
A mechanical device with a housing composed of three superimposed plates, featuring a central lever and spring mechanism that allows for locking without part rotation, enabling a secure clamping closure and easy interchangeability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rotation of parts is required to achieve secure seal, then sealing reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The device is divided into two independent parts: a stationary housing and a removable plate with pin. The housing contains three superimposed plates (fixed, central, and third plate) that form a complete housing when assembled. This segmentation allows the plate to be simply superimposed without rotation, while the internal lever mechanism provides the locking action for secure sealing.
Solution Approach 2:
The lever (4) connected to the central plate (2B) automatically performs the locking function when the plate is superimposed. The lever rotates up to the stop and engages with the pin (1A) to create the locking closure, eliminating the need for manual rotation operations by the user while ensuring reliable sealing.
2Ease of operation
If pressure fit is used to join parts, then ease of operation is improved, but sealing reliability deteriorates
Solution Approach 1:
The lever (4) is pre-positioned in the housing and the pin (1A) is pre-positioned on the plate. When the plate is superimposed, the lever automatically engages with the pin to create the locking closure before any pressure fit occurs. This preliminary locking action ensures sealing reliability while maintaining ease of operation.
Solution Approach 2:
The lever (4) acts as an intermediary mechanism between the plate and the housing. It translates the simple superimposition action into a secure locking closure by rotating up to the stop and engaging with the pin, thereby mediating between the ease of operation and sealing reliability requirements.
3Reliability
If part rotation is required for closure, then locking reliability is improved, but adaptability deteriorates
Solution Approach 1:
The device is designed with universal applicability for multiple anchoring points and various objects. The simple superimposition mechanism without rotation requirements allows the same device to be used on different surfaces and objects (domestic and industrial use), while the internal lever-pin locking mechanism ensures reliable locking for each application.
4Reliability
If complex locking mechanism is used, then sealing reliability is improved, but device complexity increases
Solution Approach 1:
The lever (4) and central plate (2B) are merged into a single integrated component. The lever is directly connected to the central plate, which is superimposed with the fixed and third plates to form the housing. This merging reduces the number of separate parts and simplifies the manufacturing process while maintaining the reliable locking closure function through the lever-pin engagement mechanism.

AI summary
A mechanical closure and fastening device, having a first part (1), made of a plate with a pin (1A) extending therefrom, the pin having first and second shaped sections in registry alignment and a narrower engaging section therebetween; and a second part (2), made of three plates (2A), (2B) and (2C), joined together, each having an opening in registry alignment and shaped to receive the first and second shaped sections when the pin is inserted thereinto; wherein plate (2B) has a rotatable plate within a fixed housing and having a lever (3) with which the rotatable plate may be rotated between an open position and a tightened, locked position within the housing, wherein in the tightened, locked position the opening in the rotatable plate is rotated out of registry alignment with the openings in plates (2A) and (2C); and wherein when the rotatable plate is in the open position, and the pin (1A) is inserted into the openings, the first and second shaped sections of pin (1A) are fixedly engaged by the openings in plates (2A) and (2C), and the engaging section therebetween is aligned with the opening in plate (2B), the rotatable plate may be rotated with the lever (3) about the engaging section to the tightened, locked position to thereby capture the first shaped section and lock the first and second parts (1) and (2) together.
