Electrical Plug Cable Fastener Using Concentric Petals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical plugs require screws for attaching wires and securing the cover, which is time-consuming and difficult, and there is a need for a more efficient method to attach and secure components without using screws.
Innovation Solution
The electrical plug employs a novelty line attacher with a hook and elongated arm to secure wires, a locking and unlocking mechanism with a tooth and slopes for the cover, and a concentrical flower mechanism with pivotally arranged petals to adjust the space and tighten the cord.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to attach wires and secure the cover in conventional electrical plugs, then the connection is reliable and secure, but the attachment process becomes time-consuming and difficult
Solution Approach 1:
The patent extracts and eliminates the screw component from the electrical plug assembly. Instead of using screws to attach wires to contacts and to secure the cover, the invention uses a push-in wire attachment mechanism where wires are inserted and held by spring-loaded contacts, and a snap-fit cover that clips onto the plug body, thereby removing the time-consuming screwing operation while maintaining secure connections
Solution Approach 2:
The wire attachment mechanism employs spring-loaded contacts that automatically grip the inserted wire with sufficient force to ensure reliable electrical connection without requiring manual screw tightening. The cover features snap-fit clips that automatically engage with the plug body, providing self-securing functionality that eliminates the need for screw fastening operations
2Strength
If screws are used to secure components in electrical plugs, then the components are firmly held, but the complexity and difficulty of assembly increases
Solution Approach 1:
The patent removes screws from the component assembly process. The wire attachment uses spring-loaded contacts that clamp onto inserted wires, and the cover is secured through snap-fit clips integrated into the plug body, eliminating the need for separate screw fasteners and reducing assembly complexity
Solution Approach 2:
The securing functions are merged into the main plug body structure. The spring-loaded wire contacts are integrated into the contact holder, and the snap-fit cover clips are molded as part of the plug housing, eliminating separate fastening components and simplifying the overall device structure

AI summary
An improved electrical plug uses a wire receiver for connecting to electrical lines. These receivers include a hook received by a cavity, the hook having an arm for moving the hook and pressing the electrical line against an electrical contact A locking and unlocking mechanism secures a plug cover to an electrical contact holder, the cover having a number of passages and slopes for locking and unlocking the cover from the contact holder. A space adjuster mechanism is provided to fasten against a cable containing the electrical lines. A number of concentrically and uniformly arranged petals slide against each other and tighten about the cable, locking it in place.
