Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional junction boxes face challenges in multidirectional wire insertion due to narrow spaces and require cumbersome screw operations, leading to unreliable wire connections that can detach under environmental shock.
Innovation Solution
The elastic-clip junction box structure features a case body with multiple direction wire sockets and conductive clips that allow for easy wire insertion and secure holding without tools, using elastic clips to maintain contact and simplify the structure, reducing the risk of detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screw and washer are used to lock the wire on the contact terminal, then the wire can be securely held, but the operation becomes cumbersome and time-consuming in narrow spaces
Solution Approach 1:
The patent replaces the screw-washer mechanical fastening system with an elastic clip mechanism. The elastic clip uses spring force to clamp the wire onto the contact terminal, eliminating the need for screws and washers. This substitution maintains secure wire holding while dramatically improving ease of operation in narrow spaces, as the elastic clip can be installed and adjusted without requiring screwdrivers or complex manual manipulation.
Solution Approach 2:
The patent changes the fastening parameter from static (screw torque) to dynamic (elastic force). The elastic clip continuously applies clamping force through its elastic deformation, adapting to wire size variations and maintaining reliable contact without requiring precise torque control. This parameter change enables both secure holding and easy operation.
2Reliability
If a screw is used to lock the wire, then the wire can be held securely, but the screw is apt to loosen due to environmental shock
Solution Approach 1:
The patent transitions from a static screw connection to a dynamic elastic clip connection. The elastic clip can dynamically adjust its clamping force in response to environmental shocks and vibrations, maintaining consistent wire contact pressure. The elastic deformation absorbs shock energy, preventing the connection from loosening while preserving connection reliability.
Solution Approach 2:
The elastic clip inherently provides cushioning against environmental shocks before they can cause loosening. The elastic material absorbs and dissipates shock energy through deformation, protecting the wire connection from the harmful effects of vibrations and impacts that would otherwise cause screw loosening.
3Volume of moving object
If wire sockets are disposed in narrow spaces, then the junction box can be compact, but it becomes hard to aim a screwdriver and operate the screw
Solution Approach 1:
The patent replaces the screw-based fastening system with an elastic clip mechanism that can be easily manipulated in confined spaces. The elastic clip requires only simple insertion and release actions that can be performed with fingers or simple tools, eliminating the need for screwdrivers and complex rotational movements that are difficult to execute in narrow spaces while maintaining compact junction box dimensions.
4Adaptability or versatility
If multiple wire sockets are disposed on the junction box, then multidirectional wire insertion is achieved, but the structure becomes more complex
Solution Approach 1:
The patent employs multiple elastic clips with different orientations (first-direction clip mouth and second-direction clip mouth) that can accommodate wires from different directions. Each elastic clip is a simple, identical component that provides universal wire holding functionality. This approach achieves multidirectional wire insertion capability while maintaining structural simplicity, as the same basic elastic clip design is reused in different orientations rather than creating complex specialized structures for each direction.

AI summary
An elastic-clip junction box structure has multidirectional wire insertion effect and holds the wires quickly. The junction box structure includes a case body and at least one conductive clip disposed in the case body. The case body is formed with a first-direction wire socket and a second-direction wire socket with different insertion directions. The conductive clip has a first-direction clip mouth in communication with the first-direction wire socket and a second-direction clip mouth in communication with the second-direction wire socket. In use, the wire can be selectively inserted into the first-direction wire socket or the second-direction wire socket. Alternatively, wires can be respectively inserted into both the first-direction wire socket and second-direction wire socket. Accordingly, wires can be selectively inserted into the elastic-clip junction box structure in multiple directions and quickly and securely held by the first-direction clip mouth and second-direction clip mouth or released therefrom.
