Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In biodrive systems, camera modules can deviate due to oscillation or external forces, leading to errors in diagnosis results when capturing images of detection targets.
Innovation Solution
A structure that fixes the camera module using a socket on a printed circuit board, incorporating a holder member with fixing units, a buffer material, and a tension member to prevent deviation, ensuring a horizontality degree of 0.05° or less and absorbing external shocks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the camera module is directly mounted on the PCB without additional fixing structures, then the device complexity is low, but the camera module position stability deteriorates due to oscillation or external forces
Solution Approach 1:
The fixing structure is divided into multiple functional components: a holder member that directly contacts and positions the camera module, multiple fixing units that secure the holder to the PCB, a buffer material that absorbs external forces, and tension members that apply pre-tension. This segmentation allows each component to perform its specific function optimally while working together to achieve overall position stability.
Solution Approach 2:
The buffer material is placed between the holder member and the camera module to provide beforehand cushioning. This cushioning layer absorbs external forces and oscillations before they can affect the camera module position, preventing deviation without requiring an overly rigid fixing structure.
2Stability of the object's composition
If a rigid fixing structure is used to prevent camera module deviation, then the position stability is improved, but the device complexity and number of components increase
Solution Approach 1:
The tension members are designed to apply a specific pre-tension force to the holder member, creating a controlled elastic constraint system. This parameter-based approach (controlling tension force) provides position stability without requiring an overly rigid or complex mechanical structure, as the stability is achieved through controlled elastic deformation rather than rigid constraints.
Solution Approach 2:
The holder member serves as an intermediary component between the camera module and the fixing units. It distributes the fixing forces from multiple fixing units evenly to the camera module, and the buffer material acts as another intermediary that mediates between external forces and the camera module, reducing the complexity of direct rigid connections.
3Stability of the object's composition
If multiple fixing units are used to secure the holder member, then the camera module position stability is improved, but the manufacturing complexity increases
Solution Approach 1:
The holder member is designed with multiple fixing holes that can accommodate various fixing unit configurations. This universal design allows the same holder member to be used with different numbers and arrangements of fixing units, simplifying manufacturing by using standardized components that can be adapted to different stability requirements without redesigning the entire assembly.
