Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a camera is miniaturized for vehicle mounting, then the camera size is reduced and design flexibility is improved, but heat dissipation becomes more difficult and noise-proof performance deteriorates
Solution Approach 1:
The camera is divided into functionally independent modules: lens unit, circuit board, connector assembly, and housing. This segmentation allows each component to be optimized independently for heat dissipation while maintaining compact overall dimensions suitable for vehicle mounting.
Solution Approach 2:
Heat dissipation is achieved by utilizing three-dimensional space within the compact camera body. The connector assembly extends along the optical axis, and heat dissipation paths are designed in multiple spatial directions, effectively using vertical and radial dimensions to dissipate heat from the circuit board without increasing the camera's footprint.
2Measurement precision
If high-speed digital signal transmission is implemented, then image quality is improved, but electromagnetic interference and noise increase
Solution Approach 1:
A connector assembly with integrated shielding structures acts as an intermediary between the circuit board and external environment. The connector includes conductive elements and shielding layers that mediate electromagnetic interference, allowing high-speed digital signals to transmit with reduced noise while maintaining image quality.
Solution Approach 2:
Electromagnetic shielding structures are built into the connector assembly before final assembly. These preliminary protective measures include conductive shields and grounded elements that preemptively counteract electromagnetic interference, preventing noise from affecting the high-speed digital signal transmission.
3Object-affected harmful factors
If effective electromagnetic shielding is implemented, then noise-proof performance is improved, but device complexity increases
Solution Approach 1:
The electromagnetic shielding function is merged with the connector assembly structure. The connector includes integrated conductive shields and grounding elements that combine signal transmission and electromagnetic protection in a single component, reducing overall device complexity while maintaining effective noise-proof performance.
Solution Approach 2:
The connector assembly serves multiple functions simultaneously: electrical connection, mechanical support, and electromagnetic shielding. This multi-functionality eliminates the need for separate shielding components, simplifying the overall device structure while achieving effective noise protection for high-speed digital signals.
4Volume of moving object
If compact camera design is achieved, then mounting flexibility is improved, but heat dissipation and noise control become more difficult
Solution Approach 1:
Heat dissipation pathways are designed utilizing three-dimensional space within the compact camera. The connector assembly and internal structures create heat dissipation channels in radial and axial directions, effectively managing thermal load without increasing the camera's external dimensions.
Solution Approach 2:
The connector assembly acts as an intermediary structure that simultaneously addresses heat dissipation and electromagnetic shielding. Its conductive elements and spatial configuration provide thermal pathways while maintaining electromagnetic protection, solving multiple problems within the compact design constraints.
