Solution Overview
Problem
Conventional electrical outlets with printed circuits face assembly challenges due to excessive clearance between reception cells and their compartments, leading to degraded performance and difficulty in precise adjustment and fixing, especially when cells are pre-soldered to the circuit.
Innovation Solution
An electrical socket design featuring a one-piece part with compartments for receiving cells and removable fixing means, including blocking abutments and material thinning for easy adjustment and firm holding, allowing precise alignment and connection to the printed circuit, reducing mechanical stress on welds and improving assembly precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cells are pre-soldered to the printed circuit, then electrical connection is established, but excessive clearance is required between cells and compartments which degrades performance and makes precise adjustment difficult
Solution Approach 1:
The invention divides the assembly into separate components: the printed circuit board with soldered cells, and the base with compartments. This segmentation allows the cells to be precisely positioned on the PCB without being constrained by the need for large clearances in the final assembly, thereby maintaining both electrical connection quality and positioning precision.
Solution Approach 2:
The patent introduces an intermediary mounting structure (the base with compartments) that mediates between the printed circuit board and the final socket assembly. This intermediary allows precise cell positioning on the PCB while providing a separate mechanism for secure mounting in the base, eliminating the need for excessive clearance.
2Reliability
If cells are pre-soldered to the printed circuit, then electrical connection is established, but fixing the cells in the base compartments becomes difficult due to stress on the welds
Solution Approach 1:
By separating the electrical connection function (soldering cells to PCB) from the mechanical mounting function (securing cells in base compartments), the invention eliminates the conflict between these two requirements. The cells can be firmly soldered without needing to be directly fixed in the base, reducing stress on the welds while maintaining assembly ease.
Solution Approach 2:
The PCB acts as an intermediary that carries the cells from the soldering process to the final mounting position. This intermediary protects the delicate solder joints from direct mechanical stress during the fixing process, making assembly easier while preserving electrical connection quality.
3Ease of operation
If excessive clearance is left between cells and compartments, then assembly is easier, but the cells cannot be adjusted precisely which degrades contact quality
Solution Approach 1:
The invention separates the assembly process into two independent stages: precise positioning on the PCB (where small clearances are acceptable) and mounting in the base (where precise adjustment is achieved through the compartment design). This segmentation allows both assembly ease and contact quality to be optimized in their respective stages.
Solution Approach 2:
The cells are preliminarily positioned and soldered on the PCB with precise alignment before being mounted in the base. This preliminary action ensures precise contact quality is achieved during the soldering stage, while the base mounting stage focuses on secure fixation, allowing both precision and ease of assembly.
