Electronic Package Module Wire Fixing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic package modules lack a sufficient fixing mechanism for wires, leading to undesirable displacement and poor welding quality during assembly and long-term use.
Innovation Solution
The electronic package module incorporates a packaging box with protruding blocks and gaps, where terminals have a welding section with a guiding surface, allowing wires to be securely connected and fixed within the module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If wires are simply moved into contact with welding sections for tin welding, then assembly process is simple, but wires may be undesirably displaced and welding quality is poor
Solution Approach 1:
The patent applies preliminary action by providing guiding surfaces on the welding sections before the wires are positioned. These guiding surfaces pre-establish the correct spatial relationship and orientation between wires and welding sections, ensuring wires are properly aligned and constrained before the welding process begins, thereby preventing displacement during assembly and welding while maintaining manufacturing simplicity
Solution Approach 2:
The guiding surfaces act as intermediaries between the wires and the welding sections. These surfaces mediate the positioning process by providing a physical interface that guides wire placement and maintains proper orientation during the welding operation, ensuring both assembly simplicity and wiring stability
2Device complexity
If no fixing mechanism is provided for wires, then device structure is simple, but wires detach during transportation or long-term use
Solution Approach 1:
The guiding surfaces are pre-formed on the welding sections to perform the fixing function. These surfaces are created during manufacturing before assembly, and they automatically constrain wire position and orientation when wires are placed against them, providing stable wire positioning without adding complex external fixing mechanisms
Solution Approach 2:
The patent applies local quality by providing fixing functionality only at the specific locations where wires need to be positioned. The guiding surfaces are localized features on the welding sections that provide constraint exactly where needed, rather than requiring a comprehensive complex fixing mechanism throughout the entire device structure

AI summary
An electronic package module includes a packaging box, multiple terminals, and a coil unit. The packaging box includes a mounting wall including a base surface, multiple protruding blocks disposed on the mounting wall, and multiple gaps each being located between adjacent two of the protruding blocks. The terminals are mounted to the mounting wall, and each have a welding section received in a corresponding one of the gaps and having a welding surface and a guiding surface bent from the welding surface. The coil unit includes multiple wires each having a connecting section connected to the welding surface and an extending section bent from the connecting section and abutting against the guiding surface.
