Rugged Plug Sliding Sheath for Easy Hook Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Common rugged plugs are difficult to plug and unplug due to their locked structure, which requires complex actions to release and disconnect.
Innovation Solution
A rugged plug design featuring an elastic inner sheath with a hook and a slidable rigid sheath, allowing for easy unplugging by moving the slidable rigid sheath away from the socket, which pushes the elastic arm and recedes the hook into the sheath, loosening the socket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rugged plug uses a locked structure (latch or hook) to prevent falling off, then connection reliability is improved, but unplugging complexity increases
Solution Approach 1:
The patent applies the dynamics principle by making the sheath movable rather than fixed. The sheath can slide between a first position (locked state with hook engaged) and a second position (unlocked state with hook retracted), enabling dynamic transition between connected and disconnected states. This resolves the contradiction by allowing reliable connection when needed while enabling easy unplugging through simple sheath movement.
Solution Approach 2:
The patent applies the nesting principle by placing the hook inside the sheath. The hook is disposed inside the sheath in the first position and can be retracted into the sheath when the sheath moves to the second position. This nested configuration allows the locking mechanism to be compact while still providing secure connection, and enables easy release by simply moving the sheath without complex manual manipulation.
2Strength
If a rugged plug uses a latch or hook structure to prevent falling, then structural strength is improved, but device complexity increases
Solution Approach 1:
The patent applies the merging principle by combining the sheath and hook into a single integrated component rather than separate parts. The hook is formed as part of the sheath structure itself, eliminating the need for additional latch mechanisms or separate locking components. This reduces device complexity while maintaining structural strength through the integrated design.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy and efficient unplugging of the rugged plug by simplifying the process, allowing users to unlock the hook and retract the plug by pulling the slidable rigid sheath away from the socket.
Implementation Method 1
The elastic inner sheath has an elastic arm, and a hook is protruded from one lateral side of the elastic arm... the actuating structure abuts against the actuating slope... moving the slidable rigid sheath in a direction away from the socket, such that the actuating structure pushes the actuating slope and biases the elastic arm

AI summary
This disclosure is directed to a rugged plug having a connector, an elastic inner sheath and a slidable rigid sheath. The connector has a coupling end. The elastic inner sheath sleeves the connector. The elastic inner sheath has an elastic arm, and a hook is protruded from one lateral side of the elastic arm. The hook protrudes from the side of the elastic inner sheath and a tip of the hook is a curved surface, an actuating slope is defined on the elastic arm, and a direction normal to the actuating slope is biased toward the coupling end of the connector. The slidable rigid sheath movably sleeves the elastic inner sheath, the slidable rigid sheath cover the actuating slope and the hook is located outside the slidable rigid sheath, the slidable rigid sheath has an actuating structure and the actuating structure abuts against the actuating slope.
