Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple telescopic cameras are mounted on a rigid camera holder structure, then measurement precision and reliability are improved, but device complexity and difficulty of maintenance increase
Solution Approach 1:
The camera holder is divided into multiple detachable brackets that can be independently removed and replaced. Each bracket holds one or more telescopic cameras, allowing selective maintenance of individual camera modules without affecting the entire system. This segmentation reduces maintenance complexity while preserving measurement precision through consistent modular mounting positions.
2Reliability
If telescopic cameras are mounted at fixed predetermined positions on a rigid structure, then measurement reliability is improved, but ease of repair and serviceability deteriorate
Solution Approach 1:
The rigid camera holder is segmented into detachable brackets that can be independently accessed and replaced. This allows technicians to service individual cameras by removing only the affected bracket, maintaining reliable fixed positions for cameras while dramatically improving ease of repair compared to a monolithic rigid structure.
Solution Approach 2:
The camera holder transitions from a completely rigid fixed structure to a semi-dynamic system with detachable brackets. This allows the structure to maintain its rigid stability during measurement while enabling dynamic reconfiguration and easy access for maintenance by allowing bracket removal and replacement.
3Ease of repair
If a modular design with detachable brackets is implemented, then ease of repair and serviceability are improved, but device complexity increases
Solution Approach 1:
The camera holder is segmented into standardized detachable brackets with consistent mounting interfaces. This segmentation improves ease of repair through modular replacement while controlling device complexity by using uniform, repeatable connection mechanisms across all brackets rather than complex custom interfaces.
Solution Approach 2:
The detachable brackets are designed as universal components that can be used in multiple positions and configurations on the camera holder. This universality improves ease of repair through interchangeable parts while reducing overall device complexity by eliminating the need for multiple specialized components.
4Productivity
If multiple cameras capture image data simultaneously, then productivity is improved, but heat generation increases affecting measurement stability
Solution Approach 1:
The camera holder extends in multiple spatial dimensions with brackets distributed throughout the available volume. This three-dimensional arrangement increases the surface area for heat dissipation and distributes thermal load across a larger volume, allowing multiple cameras to operate simultaneously at high productivity while managing heat generation through spatial distribution.
