Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for centrally positioning electronic devices on circuit boards face challenges due to manufacturing errors in device size, leading to reduced positioning accuracy and soldering quality, as either precise matching of sizes increases costs or oversized openings compromise central positioning.
Innovation Solution
A positioning device with sliding blocks, positioning plates, a cylinder, piston rod, ball, and release mechanism that allows for precise central alignment of electronic devices within circuit board openings by adjusting the positioning plates to accommodate the device and then moving it to the center.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the size of the opening of the circuit board is formed to precisely match the size of the main body of the electronic device, then the positioning accuracy is improved, but the manufacturing cost increases sharply due to the need for precise control of both dimensions
Solution Approach 1:
The patent introduces a positioning device as an intermediary tool between the electronic device and the circuit board opening. This positioning device includes positioning components that can be adjusted to match the actual size of the electronic device, thereby achieving precise positioning without requiring the circuit board opening to be precisely matched to the device size. The positioning device mediates the size mismatch issue.
Solution Approach 2:
The positioning device incorporates adjustable positioning components whose sizes can be dynamically adjusted to accommodate variations in electronic device dimensions. This dynamic adjustability allows the positioning device to adapt to different device sizes within a range, eliminating the need for precise pre-matching of the opening size to each specific device.
2Ease of manufacture
If the size of the opening of the circuit board is formed to be much larger than the size of the main body of the electronic device, then the ease of manufacture is improved, but the positioning accuracy deteriorates as it becomes difficult to centrally position the electronic device in the opening
Solution Approach 1:
The positioning device serves as an intermediary that bridges the gap between the oversized opening and the electronic device. The positioning components of the positioning device are adjusted to match the device size, and the positioning device is placed in the opening to provide accurate positioning references, thereby achieving precise central positioning despite the large opening size.
Solution Approach 2:
The positioning device divides the positioning function into separate adjustable components rather than relying on the opening itself to provide positioning. The positioning components can be independently adjusted to create precise positioning references within the larger opening, separating the function of accommodating the device from the function of positioning the device.
3Manufacturing precision
If precise control of the size of the main body of the electronic device and the size of the opening of the circuit board is implemented, then the positioning accuracy is improved, but the device complexity increases due to the need for strict dimensional control
Solution Approach 1:
The positioning device acts as an intermediary that absorbs the complexity of dimensional control. Instead of requiring precise control of both the electronic device size and the opening size, the positioning device includes adjustable positioning components that can be set to match the actual device dimensions, thereby transferring the dimensional control requirement from the opening to the positioning device, which is designed to be easily adjustable.

A positioning device including a support tab, two pairs of sliding blocks slidably mounted in the support table, a positioning plate extending vertically from on a top of each sliding block, a base on which the support table is supported, a cylinder installed in a chamber of the base, a ball received in the cylinder, a piston rod slidably mounted in the cylinder that pushes the ball to move upward in a vertical direction, so that the ball drives the two pairs of sliding blocks to move away from each other in the first horizontal direction and the second horizontal direction, respectively, until the positioning plates of the two pairs of sliding blocks abut against four inner walls of the opening of the circuit board, respectively, to allow the electronic device to be received in a positioning slot defined by the positioning plates, and a release mechanism.
