Rotary Socket Accessory Notched Spring Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rotating electrical socket mechanisms experience uneven wear and torque sensations due to notches and teeth interactions, leading to user discomfort and accelerated wear, and require complex lubrication for ball-bearing systems, increasing production costs.
Innovation Solution
A notched elastic rotation mechanism using a spring blade with complementary notches on a cylindrical part, allowing the active part to rotate relative to the support, which reduces wear and eliminates the need for lubrication, providing a balanced rotational feel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a rotary accessory is provided separately from the socket body, then the socket structure becomes more modular and easier to manufacture, but the assembly complexity increases and may create gaps between components
Solution Approach 1:
The rotary accessory is nested within the socket body such that it rotates inside the recessed cavity. The accessory fits tightly within the socket body with minimal clearance, creating a compact integrated assembly that reduces overall complexity while maintaining modular manufacturing benefits
Solution Approach 2:
The design transitions from a flat two-dimensional socket face to a three-dimensional structure with a recessed cavity that accommodates the rotary accessory. This vertical dimension allows the accessory to be housed within the socket body, eliminating gaps and creating a more integrated appearance while preserving modular assembly advantages
2Shape
If the accessory fits tightly within the socket body, then the aesthetic appearance improves and gap formation is reduced, but the manufacturing precision requirements increase
Solution Approach 1:
The socket body features a specifically designed recessed cavity with controlled dimensions and tolerance zones that accommodate the rotary accessory. The local geometry of the cavity is optimized to provide tight clearance fits in critical areas while maintaining manufacturability, achieving good aesthetic appearance without requiring extreme precision across the entire assembly
Solution Approach 2:
The design specifies particular dimensional parameters and tolerance ranges for the recessed cavity and accessory interface. By carefully selecting and controlling these geometric parameters, the design achieves tight fitting for aesthetic purposes while remaining within achievable manufacturing precision limits through proper tolerance stacking and tolerance zone selection
