Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing terminal blocks with screw-based wire fixation systems are inconvenient for mounting and removing wires due to the risk of screw slippage.
Innovation Solution
A coil spring type wire-locking terminal block with a wire locking frame and compression elastic member, where the wire locking frame is driven by a driving assembly to align with inlet and through holes for easy wire insertion and removal, and a side cover to prevent electrical shock.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screw-based wire fixation system is used, then the wire can be securely fixed, but the mounting and removal of wires becomes inconvenient and time-consuming
Solution Approach 1:
The wire locking frame is designed to be movable rather than fixed, allowing it to dynamically transition between locked and unlocked positions. The frame can be pushed down to align holes for wire insertion, then automatically returns to its original position to clamp the wire, enabling both secure fixation and easy operation.
Solution Approach 2:
The compression elastic member automatically returns the wire locking frame to its wire-clamping position after the frame is pushed down for wire insertion. This self-returning mechanism eliminates the need for additional components or complex operations to secure the wire, achieving both reliability and ease of operation.
2Ease of operation
If a movable wire locking frame with compression elastic member is used, then wire mounting and removal becomes convenient, but the device complexity increases
Solution Approach 1:
The terminal block is divided into functional modules: insulating seats, connecting terminals, wire locking frames, and driving assemblies. Each module performs a specific function, allowing for simplified design and manufacturing of individual components while achieving complex overall functionality through their coordination.
Solution Approach 2:
The wire locking frame serves multiple functions: it acts as a guide for wire insertion by aligning holes, provides clamping force through the compression elastic member, and enables easy wire removal by being movable. This multi-functionality reduces the need for separate components, thereby reducing overall device complexity.
3Reliability
If the wire locking frame is always in the wire-clamping position, then the wire is securely held, but the wire inlet hole remains exposed and creates electrical shock risk
Solution Approach 1:
The wire locking frame is designed to automatically return to its wire-clamping position after wire insertion, which preliminarily prevents the electrical shock risk by ensuring the frame is in the safe clamped position before any operation is completed. The compression elastic member continuously exerts force to maintain this safe state.
Solution Approach 2:
The side cover acts as an intermediary protective element that covers the wire inlet hole when the wire locking frame is in the wire-clamping position. This mediator prevents direct exposure of the inlet hole, thereby eliminating the electrical shock risk while maintaining wire clamping security.
