Retractable Power Plug With Nested Insulation Layers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional power plugs with sharp pins occupy space and are inconvenient to carry due to their exposed design, making them cumbersome for daily use.
Innovation Solution
A power plug design featuring a plug body with insulation layers and conducting strips, where the conducting strips are sandwiched between insulation layers and extend into a handle, forming conducting contact points that can be exposed or retracted, and include a connector with electrical connecting strips to form a power port, allowing for secure attachment and easy handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional power plugs use sharp exposed pins, then electrical connectivity is achieved, but the plug occupies more space and is inconvenient to carry
Solution Approach 1:
The plug body is inserted into the handle, with the plug body having a cross-section that matches the handle's insertion opening. The conducting strips are nested between insulation layers within the plug body structure, creating a compact nested arrangement that reduces overall volume while maintaining functionality
Solution Approach 2:
The conducting contact points are designed to be retractable, allowing them to extend when needed for electrical connection and retract when not in use. This dynamic feature reduces the exposed volume and improves portability while maintaining electrical connectivity capability
2Reliability
If conducting strips are exposed to provide contact points, then electrical connectivity is maintained, but safety is reduced due to exposed conducting elements
Solution Approach 1:
Different parts of the plug have different properties: the plug body contains conducting strips sandwiched between insulation layers for safe containment, while specific localized areas have conducting contact points that are either protected by the insulation layers or retractable, providing electrical connectivity only where needed and when needed
Solution Approach 2:
The conducting contact points are retractable, allowing them to be exposed for electrical connection and retracted for safety. This dynamic feature ensures that conducting elements are only exposed when necessary for functionality, reducing safety hazards during storage and transport
3Ease of operation
If the plug design is simplified for portability, then ease of carrying is improved, but manufacturing complexity may increase
Solution Approach 1:
The power plug is divided into distinct segments: a handle with wiring path and a separate plug body with conducting strips and insulation layers. These segments can be manufactured separately and then assembled through the insertion opening, allowing for specialized manufacturing of each component while maintaining overall portability
Solution Approach 2:
The plug body serves multiple functions: it provides structural support, contains the conducting strips between insulation layers, provides wiring pathways, and houses the retractable conducting contact points. This multi-functionality reduces the need for additional separate components, simplifying the overall design while maintaining portability

AI summary
A power plug is provided. The power plug may include a plug insert having a handle, and a plug body including a plurality of insulation layers and a plurality of conducting strips sandwiched between the pluralities of insulation layers. Each of the plurality of conducting strips may have an end extending into the handle and the other end forming or electrically connected to a conducting contact point exposed on a surface of the plug body.
