Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional medication containers with automatic pop-up lids require multiple components and complex assembly processes, leading to high production costs and reduced efficiency.
Innovation Solution
A medication container design featuring a lid with an integrally formed cover plate and elastic soft rubber insert, which pivots relative to the container body through elastic deformation, eliminating the need for a pivot shaft and simplifying the structure, while ensuring an automatic pop-up function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a torsion spring and pivot shaft are used to achieve automatic lid pop-up, then the automatic pop-up function is achieved, but the number of components increases and assembly complexity increases
Solution Approach 1:
The patent merges the pivot shaft and torsion spring into a single integrated pivot structure. The pivot structure includes a pivot column and pivot arm that work together to provide both the rotational axis and the elastic restoring force, eliminating the need for separate torsion spring and pivot shaft components while maintaining the automatic pop-up function.
Solution Approach 2:
The pivot structure serves multiple functions simultaneously: it acts as the rotational axis (pivot shaft function), provides the elastic restoring force (torsion spring function), and serves as a structural connector between the lid and container body. This multi-functionality reduces the overall component count while maintaining all necessary functionalities.
2Ease of operation
If a torsion spring and pivot shaft are used to achieve automatic lid pop-up, then the automatic pop-up function is achieved, but assembly steps become cumbersome and production cost increases
Solution Approach 1:
The pivot structure integrates the pivot column and pivot arm into a single component that can be installed in one assembly step. The elastic deformation portion is formed as an integral part of the pivot structure, eliminating the need for separate assembly steps for installing torsion springs and securing pivot shafts, thereby improving assembly efficiency and reducing labor costs.
3Ease of operation
If the lid is connected via a pivot shaft with torsion spring, then automatic pop-up is achieved, but the structure becomes complex
Solution Approach 1:
The lid connection structure is simplified by merging the pivot shaft and torsion spring into a single pivot structure. The pivot column provides the rotational axis while the pivot arm with elastic deformation portion provides both the connection to the lid and the elastic restoring force, creating a more compact and simpler overall structure.
Solution Approach 2:
The pivot arm incorporates an elastic deformation portion that functions as a flexible element. This elastic portion can bend and store energy, providing the necessary restoring force for automatic pop-up without requiring a separate coil spring, thus simplifying the mechanical structure.

Function Achieved in This Case
Reduces production costs and enhances assembly efficiency by minimizing components to two parts, while maintaining user-friendly access to medication through the automatic lid mechanism.
Implementation Method 1
the elastic insert is deformed in response to being pulled by the rear end of the cover plate
Implementation Method 2
the elastic insert recovers from deformation and drives the cover plate to pivot to an open state
