Solution Overview
Problem
Conventional pacifier clips are complex to assemble, costly, and prone to deformation when sanitized, leading to structural weaknesses and increased production costs, while also posing challenges in securely clipping and releasing the pacifier.
Innovation Solution
A pacifier clip design featuring a base sheet with sheet columns and a mobile clipping member with a step-shaped structure, a pulling member with angled flanges, and a tying tool, allowing for secure clipping and easy release through an eccentric action mechanism, simplifying assembly and reducing production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a clamping member is added to secure the flanges, then the structural strength and anti-loosening performance are improved, but the assembling difficulty and production cost increase
Solution Approach 1:
The patent merges the clamping function and latching function into a single integrated clamping member structure. The clamping member includes both the clamping portion that secures the flanges and the latching portion that engages with the latching member, eliminating the need for separate components and simplifying assembly while maintaining structural strength
Solution Approach 2:
The clamping member is designed to perform multiple functions simultaneously: it clips the flanges together, latches to prevent release, and provides structural support. This multi-functional design reduces the number of components needed and simplifies the overall assembly process
2Reliability
If a clamping member is used to secure flanges, then anti-loosening performance is improved, but the production cost increases
Solution Approach 1:
By combining the clamping and latching functions into one member, the patent reduces the total number of components that need to be manufactured, stored, and assembled, thereby reducing production costs while maintaining reliable anti-loosening performance through the integrated design
3Strength
If the clamping member is made rigid for strong clamping, then the clipping effect is improved, but the structure becomes prone to deformation during high temperature sanitization
Solution Approach 1:
The patent employs elastic material properties and geometric design to achieve the required clipping effect without excessive rigidity. The clamping member is designed with appropriate thickness and width dimensions that provide sufficient clamping force while maintaining flexibility to withstand thermal stress during sanitization without deforming
4Ease of operation
If the pulling member is made long for easy operation, then the ease of use is improved, but the device complexity increases
Solution Approach 1:
The pulling member is designed as a separate, independent component that can be easily attached and detached from the base sheet. This segmentation allows for simple assembly while providing a long handle for easy operation, and the modular design keeps the overall device complexity manageable

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 ensures secure clipping and anti-loosening, reduces assembly complexity, and maintains structural integrity, while being cost-effective and compliant with safety regulations, including those of the European Union.
Implementation Method 1
the connecting sheet and the first and the second flanges of the latching member are buckled and clamped by an elastic clamping member
Implementation Method 2
two ends of an oblique support arm formed with a hook-like shape in the mid portion thereof are respectively connected to a pivotal shaft received in the shaft slot

AI summary
The present invention relates to a pacifier clip, which comprises a base sheet, a mobile clipping member, a pulling member and a tying tool. When the pulling member is pulled, in the rotating motion, an angled flange of the pulling member utilizes an eccentric action to optionally allow an angled part or an inclined cutting plane of the angled flange to be abutted against or adjacent to an oblique support arm of the mobile clipping member, so a passive sheet of the mobile clipping member is downwardly moved or upwardly raised, and tooth rows of the passive sheet and tooth lines of the base sheet are engaged for forming a clipping status or forming a gap in between for forming a releasing status.
