Vehicle Connector With Deformable Portion for Vibration Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle-mounted display devices experience higher defect rates due to vibration, particularly with components on circuit boards becoming de-soldered, loosened, and damaged from long-term impact, leading to issues like blurred or non-functional screens.
Innovation Solution
A connector with a deformable supporting portion and a fastening mechanism is introduced, which connects components of the display device to absorb vibration impacts, preventing damage by allowing flexible connection between the circuit board and the housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If rigid connection is used between circuit board and housing, then structural stability is improved, but vibration resistance deteriorates causing component damage
Solution Approach 1:
The patent employs a flexible connector with a deformable supporting portion that can bend and deform under vibration impact. This flexible structure absorbs vibration energy while maintaining the connection between the circuit board and housing, preventing rigid stress transmission that would cause component damage.
Solution Approach 2:
The connector transitions from a static rigid connection to a dynamic flexible connection. The deformable supporting portion can dynamically adjust its shape and stiffness in response to vibration forces, providing stability during normal operation while absorbing shock during vibration events.
2Reliability
If flexible connection is used between circuit board and housing, then vibration resistance is improved, but connection strength deteriorates
Solution Approach 1:
The connector is divided into distinct functional segments: a limiting connection portion for rigid mounting to the housing, a deformable supporting portion for flexible vibration absorption, and a fastening portion for securing the circuit board. This segmentation allows each part to optimize its local function while contributing to overall system performance.
Solution Approach 2:
Different portions of the connector have different mechanical properties tailored to their specific functions. The limiting connection portion and fastening portion use rigid materials for strong connection, while the intermediate supporting portion uses flexible material for vibration absorption. This local differentiation resolves the contradiction between overall strength and local flexibility.
