Circuit Board Bending Adjuster for Inspection Device Flatness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Circuit boards in inspection devices often become bent due to applied forces or weight, leading to poor electrical contact and limiting the number of circuit parts that can be mounted, as existing solutions that attempt to flatten them restrict the mounting density.
Innovation Solution
A circuit device with a housing and a bending adjuster that includes a reference member and a distance adjuster to deform the circuit board, allowing for adjustment of bending without limiting the density of mounted circuit parts, by fixing a portion of the circuit board to the housing and using a reference member spaced from the non-fixed portion to adjust the distance between them.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If traditional flattening methods are used to correct bending of circuit boards, then flatness is improved, but the density of circuit parts that can be mounted is reduced
Solution Approach 1:
The circuit board is divided into a fixed portion (attached to housing) and a non-fixed portion (with bending adjuster). This segmentation allows independent adjustment of the non-fixed portion to correct bending without affecting the entire board, thus maintaining mounting density while achieving flatness.
Solution Approach 2:
A bending adjuster is introduced as an intermediary mechanism between the fixed and non-fixed portions of the circuit board. This bending adjuster includes a penetrating member that can be adjusted to change the distance between the fixed and non-fixed portions, enabling precise control of board flatness without limiting circuit part mounting.
2Stability of the object's composition
If the circuit board is made completely fixed to the housing, then structural stability is improved, but the ability to adjust bending is lost
Solution Approach 1:
The circuit board is segmented into fixed and non-fixed portions, allowing the fixed portion to provide structural stability while the non-fixed portion maintains adjustability for bending correction.
Solution Approach 2:
The bending adjuster is designed with adjustable components (penetrating member with adjustable distance) that can be dynamically modified to correct bending. This dynamic adjustability is maintained only in the non-fixed portion, while the fixed portion remains stable.
3Measurement precision
If the reference member is placed close to the circuit board, then adjustment precision is improved, but the mounting area for circuit parts is reduced
Solution Approach 1:
The reference member is positioned only in the non-fixed portion of the circuit board, creating local adjustment capability without affecting the overall mounting area. This localized approach allows precise bending adjustment in the specific region where needed while preserving circuit part mounting in other areas.
