Pill Box Cover Elastic Buckle Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pill boxes have an upper cover that is integrally connected with the main body, leading to insufficient opening angle and ease of damage due to constant deformation, making it inconvenient to access pills and reducing the device's service life.
Innovation Solution
A pill box design featuring a buckled elastic piece with a bending portion that elastically deforms to securely close the box and a pressing portion to easily open it, allowing for complete opening and reducing the force required for operation, along with a transparent window for pill observation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the upper cover is integrally connected with the main body to ensure structural integrity, then the structural strength is improved, but the opening angle becomes insufficient and the cover is prone to damage due to constant deformation
Solution Approach 1:
The pill box is divided into separate components: a main body and a removable box cover that can be completely separated. This segmentation allows the cover to open to a full 180 degrees without being constrained by integral connection, while maintaining structural integrity through dedicated connecting mechanisms like hinges or snap-fits.
Solution Approach 2:
The connecting mechanism between the box cover and main body is designed to be dynamic rather than rigid. The hinge or snap-fit connection allows the cover to rotate and move freely during opening and closing operations, enabling complete opening while the elastic piece provides controlled resistance to prevent accidental opening.
2Ease of operation
If the upper cover is deformed and bent at the closed position to enable automatic opening, then the ease of operation is improved, but the upper cover becomes easily damaged due to long-term deformation
Solution Approach 1:
An elastic piece is introduced as an intermediary component between the box cover and main body. This elastic piece deforms during closing to provide automatic locking, while the box cover itself remains rigid and undamaged. The elastic piece absorbs the deformation stress, protecting the main structural components from fatigue and damage.
Solution Approach 2:
The elastic piece undergoes controlled parameter changes (deformation) during operation to achieve automatic locking and opening functions. By concentrating the deformation in a replaceable elastic component rather than the permanent box cover structure, the service life of the main components is significantly extended.
3Reliability
If the box cover is completely closed to ensure secure storage, then the protection of pills is improved, but the force required to open the box increases
Solution Approach 1:
The elastic piece is designed to automatically engage with the box cover when the box is closed, providing self-locking without requiring additional force. This self-service mechanism ensures secure storage while minimizing the force needed for opening, as the elastic piece naturally releases when the box is opened.
Solution Approach 2:
The elastic piece provides slightly more closing force than necessary for secure storage, ensuring reliable sealing. However, this excessive force is distributed over the elastic deformation rather than concentrating stress on the box cover, making opening easier while maintaining secure closure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enhances the ease of opening and closing the pill box, increases its service life by reducing pressing force, and allows for quick access to pills while maintaining a secure closed state, addressing the limitations of conventional designs.
Implementation Method 1
the bending portion of the elastic piece is squeezed by force and elastically deforms and tightly engages with an abutment surface of the box cover
Implementation Method 2
by pressing the pressing portion, the bending portion of the elastic piece is restored to an original shape and the box cover connected with the box body is opened

AI summary
A pill box includes a box body. The box body includes an accommodating chamber defining an opening and receiving pills. A box closing the accommodating chamber is arranged on the accommodating chamber. A connecting end of the box cover is hinged to a rear end of the box body. An elastic piece and a limiting groove are disposed on the rear end of the box body. A clamping seat is arranged on the connecting end of the box cover. A bending portion is arranged on one end of the elastic piece. A fixing portion is arranged on another end of the elastic piece. The bending portion passes through the clamping seat and is exposed. When the box cover is buckled with the box body, the bending portion is deformed by being squeezed and tightly engages with the box cover, and the fixing portion extends downward into the limiting groove.
