Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing terminal blocks for wire connection are inconvenient to operate and difficult to use due to limited trigger modes, complex installation processes, and the inability to handle multi-directional wiring, making them inefficient for fast and easy wire connection.
Innovation Solution
A terminal block design featuring a casing with two aligned components, each equipped with pressing keys that trigger the opening or closing of a wire clamping body, utilizing an arc-shaped spring piece and snap-fit mechanism for easy assembly and disassembly, allowing for rapid wire insertion and disconnection, and accommodating multiple wires from different directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a tightening fastener is used to clamp wires, then the wire compression is effective, but the tightening operation becomes troublesome and the wiring process is inconvenient
Solution Approach 1:
The patent replaces the traditional mechanical tightening fastener system with an elastic piece-based clamping system. The elastic piece automatically clamps the wire through elastic deformation, eliminating the need for manual tightening operations while maintaining effective wire compression. This substitution transforms a complex mechanical tightening process into a simple insertion operation.
Solution Approach 2:
The elastic piece is designed to automatically clamp the wire upon insertion without requiring additional tightening operations. The wire itself triggers the clamping action by being inserted into the elastic piece, which then deforms elastically to secure the wire. This self-service mechanism eliminates the need for separate tightening fasteners and operations.
2Ease of operation
If an elastic piece is used to clamp wires, then the wiring process is simplified, but the trigger mode is limited and the operation becomes inconvenient with many steps
Solution Approach 1:
The terminal block is divided into multiple independent terminal units, each with its own elastic piece and pressing key. This segmentation allows each terminal to be operated independently, simplifying the overall operation. The pressing key mechanism is separated from the elastic piece, allowing the key to trigger the elastic piece's clamping action through a simple pressing motion, reducing the number of operational steps.
Solution Approach 2:
The elastic piece is designed with dynamic clamping capability, where the clamping force automatically adjusts based on the wire insertion. The pressing key provides a dynamic trigger mechanism that releases the elastic piece to clamp the wire. This dynamic design eliminates fixed trigger modes and allows flexible operation without multiple discrete steps.
3Device complexity
If a traditional terminal block design is used, then the structure is simple, but the wiring direction is limited to the same direction only
Solution Approach 1:
The terminal block is designed with multiple terminal units that can accommodate wires from different directions. Each terminal unit is universally designed to accept wire insertion from various angles, not limited to a single direction. The casing structure incorporates multiple openings and access points that enable multi-directional wiring while maintaining overall structural simplicity through modular design.
Solution Approach 2:
The terminal block design adds dimensional versatility by allowing wire insertion from multiple directions (not just linear). The casing is configured with openings and internal structures that accommodate wires approaching from different spatial dimensions, transforming a single-direction linear design into a multi-directional three-dimensional wiring solution while keeping the overall structure simple.
