Double Socket Outlet Asymmetric Angular Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fixed double socket-outlets cannot fit into standard mounting boxes designed for single sockets, leading to issues with cable overlap and reduced durability due to symmetric designs that restrict flexible assembly.
Innovation Solution
A fixed double socket-outlet design featuring socket-contact openings arranged at an angle between 38 and 42 degrees, allowing for parallel insertion of angled plugs and cables, with asymmetric links for earthing contacts to maintain structural integrity and prevent deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a double socket-outlet is designed with symmetric structure to retain form and prevent deformation, then reliability is improved, but the device cannot fit into a mounting box designed for single socket-outlet
Solution Approach 1:
The patent applies asymmetry by arranging the two socket-outlet openings at an angle of 38-42 degrees relative to the sides of the rectangular cover-plate, rather than using a symmetric arrangement. This asymmetric angular configuration allows the double socket-outlet to fit into a mounting box designed for single sockets while maintaining structural integrity through the fixed links that connect the socket-contacts in parallel between the two openings.
2Device complexity
If socket-outlet outlets are arranged on the same axis to simplify structure, then device complexity is reduced, but cable overlap occurs causing plugs to not fit properly
Solution Approach 1:
The patent resolves the cable overlap issue by arranging the socket-outlet openings at an asymmetric angle of 38-42 degrees relative to the cover-plate sides, which prevents the angled cables from overlapping when plugs are inserted, unlike traditional same-axis arrangements.
Solution Approach 2:
The patent changes the angular parameter of the socket openings from the conventional 0 degrees (same axis) to 38-42 degrees, which optimizes the cable routing and prevents overlap, allowing both angled plugs to be inserted simultaneously without interference.
3Quantity of substance
If extension leads and portable socket-outlets are used to increase socket availability, then the number of available sockets is increased, but device complexity and loss of substance increase
Solution Approach 1:
The patent merges two separate socket-outlets into a single fixed double socket-outlet unit that fits into one mounting box, eliminating the need for extension leads or multiple portable sockets. This integration increases the number of available sockets while reducing device complexity and eliminating unnecessary components.
Solution Approach 2:
The patent creates a universal double socket-outlet that provides multiple functions (two sockets) within a single mounting box footprint, replacing the need for multiple separate socket solutions and extension leads, thereby simplifying the overall electrical infrastructure.
