Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for attaching devices to the edge of circuit boards are time-consuming and lack accuracy, requiring manual dexterity or expensive fixtures, as they involve manually holding or using external fixtures to ensure precise placement and soldering without movement during the process.
Innovation Solution
A system that includes a controller, a circuit board altering device, a placement device, and an attachment device, which removes a sacrificial part of the circuit board, inserts a holder device, and attaches devices using solder paste and a predefined solder flow process, allowing for automated or manual operation with improved precision and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual holding or external fixtures are used to attach devices to circuit board edge, then placement accuracy is improved, but device complexity and operation difficulty increase
Solution Approach 1:
The patent introduces a holder device as an intermediary component that temporarily supports the device during soldering. The holder is inserted into a recess in the circuit board, providing stable support without requiring complex external fixtures. This mediator simplifies the overall system while maintaining placement accuracy during the attachment process.
Solution Approach 2:
The circuit board is segmented into a main body and a recess portion that accommodates the holder device. By dividing the board structure, the patent creates a dedicated space for device support that simplifies the attachment process and reduces the need for complex external fixtures, thereby improving placement accuracy without increasing overall complexity.
2Manufacturing precision
If manual holding is used to prevent device movement during soldering, then operation precision is improved, but productivity decreases
Solution Approach 1:
The holder device is designed to be self-supporting once inserted into the recess. It automatically provides stable support for the device during soldering without requiring continuous manual intervention. This self-service mechanism maintains placement accuracy while significantly improving productivity by eliminating the need for operators to continuously hold and stabilize devices during the attachment process.
3Manufacturing precision
If external fixtures are used to ensure precise placement, then manufacturing precision is improved, but ease of operation deteriorates
Solution Approach 1:
The holder device serves as a simple intermediary that bridges the circuit board and the device being attached. By inserting the holder into a pre-formed recess, operators gain stable support for precise placement without needing to manipulate complex external fixtures. This intermediary simplifies the operation while maintaining high placement accuracy.
4Reliability
If complex fixtures or machinery are used to prevent device movement, then reliability of attachment is improved, but device complexity increases
Solution Approach 1:
The holder device is a simple intermediary component that provides reliable support during soldering. Its straightforward design—essentially a support structure that fits into a recess—maintains attachment stability without introducing complex machinery or fixtures, thereby achieving reliability while minimizing device complexity.
5Manufacturing precision
If manual dexterity is required for precise placement and soldering, then manufacturing precision is improved, but ease of operation deteriorates
Solution Approach 1:
The holder device provides self-service by automatically stabilizing the device once inserted into the recess. This eliminates the need for operators to continuously adjust and hold the device with manual dexterity. The holder's design inherently provides the stability needed for precise soldering, making the operation simpler while maintaining high placement accuracy.
