Electrical Socket Rotary Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electrical sockets fail to securely lock electrical plugs, leading to easy detachment and potential safety hazards and equipment damage.
Innovation Solution
An electrical socket design featuring a main body with socket openings, a detachable cover member, and a rotary member that rotates to prevent contact blades from sliding out, using conductor pieces with extending pieces and grooves for secure locking, and a threaded shaft for stable connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional electrical socket without locking mechanism is used, then the device complexity is low, but the electrical plug can detach easily affecting safety and normal use
Solution Approach 1:
The rotary member is designed to rotate between a first position (locked state) and a second position (unlocked state), transforming a static socket into a dynamic locking system. This dynamic mechanism provides reliable locking while maintaining operational simplicity through rotational movement.
Solution Approach 2:
The rotary member is disposed within the main body of the socket, with its end inserting into the main body. The conductor piece with extending piece is nested within the socket structure, creating a compact integrated design that adds locking functionality without significantly increasing overall device complexity.
2Reliability
If a rotary member with conductor piece is added to create locking mechanism, then the electrical plug is securely locked, but the device complexity increases
Solution Approach 1:
The conductor piece is integrated with the extending piece that directly interacts with the rotary member's end. The cover member is merged with the inserting part that connects to the main body. These merged components reduce the number of separate parts while maintaining the locking functionality and structural integrity.
Solution Approach 2:
The conductor piece serves dual functions: electrical conduction and mechanical locking engagement with the rotary member. The rotary member provides both rotational movement for operation and positioning for locking. This multi-functionality reduces the need for separate dedicated components.
3Reliability
If the end of rotary member abuts the conductor piece to prevent sliding out, then the contact blade is securely locked, but the manufacturing precision requirements increase
Solution Approach 1:
The extending piece of the conductor piece has a specific localized structure that engages with the end of the rotary member. This localized engagement point concentrates the locking action at a specific area, requiring precision only at that critical interface rather than throughout the entire component assembly.
Solution Approach 2:
The rotary member is able to rotate relative to the main body around a central axis, maintaining equipotential rotational movement. This ensures consistent engagement between the end of the rotary member and the conductor piece throughout the rotation range, reducing sensitivity to manufacturing variations.
4Ease of manufacture
If the cover member is made detachable from the main body, then the ease of manufacture and repair is improved, but the reliability of connection may be affected
Solution Approach 1:
The cover member is segmented from the main body, allowing separate manufacturing and assembly. The inserting part of the cover member can be independently manufactured and then assembled into the main body, simplifying production and enabling replacement without replacing the entire socket.
Solution Approach 2:
The inserting part acts as an intermediary component between the cover member and the main body. This intermediate element provides a standardized connection interface that ensures reliable assembly while maintaining the detachable nature of the cover member for ease of manufacture and repair.
