Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wet tissue flap covers suffer from connection failures due to repeated use, leading to separation of the upper and lower flap covers, compromising tightness, hygiene, and safety by allowing moisture loss and bacteria breeding.
Innovation Solution
A quick-detachable and replaceable design featuring a hinge structure with a clamping slot at the joint between the upper and lower flap covers, utilizing an elastic clamping mechanism to ensure reversible opening and closing, preventing breakage and enabling easy replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the upper flap cover and lower withdrawal cover are integrated to form a collapsible connection, then the structure is simple, but the connection breaks after repeated turnover or pull
Solution Approach 1:
The connection structure is divided into separate components: a hinge structure with support portions and hinge shaft, and a separate clamping slot component. This segmentation allows each part to perform its specific function - the hinge provides rotational movement while the clamping slot provides secure attachment, together resolving the contradiction between simplicity and reliability.
Solution Approach 2:
The connection structure incorporates dynamic elements including the hinge shaft that rotates within the clamping slot, and the elastic material that provides flexible clamping force. This dynamic design allows the connection to accommodate repeated opening and closing movements while maintaining secure attachment, preventing breakage after repeated use.
2Stability of the object's composition
If the upper flap cover and lower flap cover are connected by a connecting shaft or connecting rod, then the connection is stable, but the connecting shaft or connecting rod breaks easily after repeated use
Solution Approach 1:
The rigid connecting shaft or rod is replaced with a dynamic hinge structure that includes an elastic material. The elastic material allows the hinge shaft to flex and absorb stress during repeated opening and closing operations, maintaining connection stability while preventing breakage through flexible stress distribution.
Solution Approach 2:
The material properties of the connection structure are changed by introducing elastic material into the clamping slot. This changes the mechanical parameters from rigid to flexible, allowing the connection to maintain stability through elastic deformation rather than rigid resistance, thereby preventing breakage after repeated use.
3Reliability
If the connection between upper and lower flap covers is fixed, then the tightness is maintained, but the replacement is difficult
Solution Approach 1:
The connection structure is segmented into detachable components - the hinge structure and the clamping slot - that can be easily separated. The clamping slot is designed to release the hinge shaft with simple upward movement, enabling easy replacement while maintaining tightness during closed operation. This segmentation resolves the contradiction between fixed connection for tightness and ease of replacement.
