Flush-Mounted Junction Box Insert for Compact Socket Spacing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing installation sockets for electrical devices face challenges in achieving a stable connection between neighboring units and maintaining a prescribed distance, especially when the distance is less than the diameter of the socket, making it difficult to arrange multiple sockets side by side effectively.
Innovation Solution
The design features a recessed flattened wall part on one of the installation sockets, allowing for a second socket to be inserted closely, creating a stable and compact unit with complementary guide elements and locking mechanisms to ensure secure attachment without compromising stability or visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If installation boxes are arranged in series with minimal distance, then the distance between adjacent boxes is reduced, but the connection stability between boxes deteriorates
Solution Approach 1:
The installation box is divided into a main body and a separate insert that can be removed. The insert contains guide elements that facilitate precise positioning when boxes are arranged in series, while the main body provides structural stability. This segmentation allows the box to function as a single unit during installation and as a modular component when arranged in series with minimal spacing.
Solution Approach 2:
A recess is introduced as an intermediary structure on the flattened wall part, which receives the insert containing guide elements. This recess acts as a mediator that enables the second installation box to be positioned at minimal distance while maintaining connection stability through the guide elements that ensure proper alignment and engagement between adjacent boxes.
2Ease of operation
If a recess is provided on both flattened wall parts, then symmetry and ease of insertion are improved, but the ability to maintain compact series arrangement deteriorates
Solution Approach 1:
The recess is provided on only one of the two flattened wall parts, creating an asymmetric design. This asymmetry is intentional and functional: it allows the insert to be inserted from one side only, which enables the second installation box to be positioned closely against the first box. The asymmetric placement of the recess optimizes the series arrangement by allowing minimal spacing while maintaining ease of insert insertion through the designated opening.
3Stability of the object's composition
If the insert is permanently fixed, then connection stability is improved, but ease of disassembly and reconfiguration deteriorates
Solution Approach 1:
The connection between the insert and the main body is designed to be dynamic rather than static. The insert can be firmly retained during normal operation through friction and geometric interlocking, providing stability. However, when needed, the insert can be easily removed by applying slight force or using a tool to overcome the retention mechanism. This dynamic design allows the system to switch between stable connection and easy disassembly based on operational requirements.
