Solution Overview
Problem
Conventional heating devices face challenges in configuring secure connections between positive terminal pins and power connectors due to limited space within or above the PCB casing, leading to potential damage to internal elements and lack of flexibility in positioning and configuring these components.
Innovation Solution
A heating device design where the terminal pin is connected to a bus bar extending out of the PCB casing, with a power connector housing located outside the casing, allowing for secure connections and flexible positioning without modifying the casing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the terminal pin and power connector are disposed inside the PCB casing, then the connection is compact, but there is insufficient space for secure connection and risk of damage to internal elements
Solution Approach 1:
The patent transitions the terminal pin and power connector from a two-dimensional arrangement inside the PCB casing to a three-dimensional arrangement extending outside the casing. The terminal pin protrudes from the PCB casing, and the power connector is positioned externally, creating additional spatial dimensions for secure connection without increasing the footprint of the PCB casing itself.
Solution Approach 2:
The patent extracts the terminal pin and power connector connection interface from the confined internal space of the PCB casing. By positioning the terminal pin to extend outside the casing and the power connector externally, the connection elements are taken out of the restricted environment, providing sufficient space for secure engagement while isolating internal PCB elements from potential damage.
2Reliability
If the PCB casing size is increased to accommodate terminal pin and power connector, then secure connection is achieved, but packaging space constraints are violated
Solution Approach 1:
The patent utilizes the vertical dimension and external space around the PCB casing to position the terminal pin and power connector. Instead of increasing the horizontal footprint of the casing, the terminal pin extends outward from the casing surface, and the power connector is positioned in the external three-dimensional space, achieving secure connection without expanding the casing's base area.
Solution Approach 2:
The terminal pin acts as an intermediary element that bridges the internal PCB circuitry and the external power connector. It extends from the PCB casing to provide a connection interface outside the casing, enabling secure engagement with the power connector while maintaining the original casing dimensions and protecting internal elements.
3Adaptability or versatility
If the terminal pin and power connector are positioned flexibly, then configuration options increase, but positioning precision decreases
Solution Approach 1:
The patent segments the connection system into distinct modular components: the PCB casing, the terminal pin extending from it, and the externally positioned power connector. This segmentation allows each component to be manufactured and positioned independently with high precision, while the overall system maintains flexibility in configuration. The terminal pin's extension from the casing provides a standardized interface that can be adapted to different power connector positions.
