Double Binder Clip with Curled Edges and Spring Bias
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing binder clips lack a double structure with a single continuous clip body that effectively secures and organizes multiple folders and packets of paper, as they do not incorporate spring-biased panels and pivotally engageable levers for enhanced usability.
Innovation Solution
A double binder clip with a single continuous clip body featuring spring-biased outer panels, U-shaped inner panels, curled bottom edges, and pivotally engageable semi-flexible looped wire levers, allowing for secure organization of multiple packets of paper by lifting the curled edges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single continuous clip body is used, then manufacturing simplicity is improved, but the ability to securely hold multiple packets of paper deteriorates
Solution Approach 1:
The single continuous clip body is segmented into multiple functional panels including a U-shaped inner panel and two outer panels, each serving specific purposes. The inner panel forms the basic clipping structure while the outer panels provide additional securing mechanisms with curled bottom edges, enabling the clip to hold multiple packets securely despite being made from one continuous piece of material
Solution Approach 2:
The patent introduces a third dimension by creating curled bottom edges on the outer panels that extend downward from the main clip body. This vertical dimension allows the curled edges to engage with the bottom of packets of paper, adding a layer of securing capability that goes beyond the traditional two-dimensional clipping action, thereby enabling secure holding of multiple packets
2Reliability
If spring-biased outer panels are added, then the security of holding packets is improved, but the device complexity increases
Solution Approach 1:
The spring mechanism is merged directly into the continuous clip body structure rather than being a separate component. The outer panels are formed as integral parts of the continuous material, with the spring action built into the panel itself through its formation and positioning, combining the securing function with the structural element to minimize additional complexity
Solution Approach 2:
The spring-biased outer panels automatically adjust and adapt to the packets being clipped. The spring mechanism provides self-regulating pressure that maintains secure holding without requiring external adjustment or complex control systems, allowing the clip to serve itself in maintaining optimal clipping force
3Ease of operation
If pivotally engageable levers are added, then ease of operation is improved, but the device complexity increases
Solution Approach 1:
The levers are designed to be pivotally engageable, transforming from static structures to dynamic components that can rotate and adjust. This allows the levers to move between engaged and disengaged positions, providing operational flexibility and ease of use when loading and unloading packets, while the pivot mechanism remains integrated into the existing panel structure

Function Achieved in This Case
The double binder clip effectively secures and organizes multiple packets of paper by allowing users to lift the curled edges, providing improved organization and security through its unique structural design.
Implementation Method 1

AI summary
A double binder clip including a single continuous clip body. The single continuous clip body includes a right outer panel, a left outer panel, a substantially U-shaped inner panel, a right top panel disposed between the right outer panel and the substantially U-shaped inner panel, a left top panel disposed between the left outer panel and the substantially U-shaped inner panel, a right curled bottom edge disposed on a bottom surface of the right outer panel, and a left curled bottom edge disposed on a bottom area of the left outer panel. The right outer panel and the left outer panel are spring-biased toward one another. Each of a right lever and a left lever of a pair of looped wire levers is pivotally engageable within each of the right curled bottom edge and the left curled bottom edge, respectively, of the single continuous clip body.
