Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If components are arranged in an ad hoc manner, then the LiDAR system can be assembled, but accessibility and removability of components deteriorates
Solution Approach 1:
The LiDAR system is divided into modular components (emitter module, receiver module, scanner module, etc.), each mounted on separate brackets that can be independently accessed, removed, and replaced. This segmentation allows maintenance of individual components without disassembling the entire system.
Solution Approach 2:
The frame structure serves multiple functions: it provides mechanical support, defines component positions, enables accessibility through openings, and facilitates assembly/disassembly. The universal frame design accommodates various modular components while maintaining ease of access and removability.
2Ease of manufacture
If components are arranged in an ad hoc manner, then the LiDAR system can be assembled, but component removability deteriorates
Solution Approach 1:
Each functional component is segmented into its own module mounted on a separate bracket, allowing individual removal and replacement. The emitter, receiver, and scanner can be independently serviced without affecting other components.
Solution Approach 2:
The system transitions from a fixed, integrated arrangement to a dynamic, modular configuration where components can be easily inserted and removed. The brackets and frame structure enable flexible assembly and disassembly operations.
3Ease of operation
If the entire LiDAR system is disassembled for component replacement, then component access is improved, but assembly time and productivity deteriorates
Solution Approach 1:
By segmenting the system into independently accessible modules mounted on separate brackets, individual components can be replaced without disassembling the entire system, significantly reducing maintenance time and improving productivity.
Solution Approach 2:
Components are pre-mounted on brackets with defined attachment points before final system assembly. This preliminary arrangement on standardized brackets enables quick interchange during maintenance without requiring complex disassembly procedures.
4Ease of manufacture
If components are connected with cables in an ad hoc arrangement, then the system can be assembled, but cable complexity and manufacturing difficulty increases
Solution Approach 1:
Multiple cable connections are merged into integrated cable assemblies that route through defined pathways in the frame. This consolidates the complex cable management into standardized routing structures, reducing overall system complexity.
Solution Approach 2:
The frame structure serves as an intermediary that provides defined cable routing pathways and mounting points. This mediator structure organizes cable connections systematically, reducing the complexity of cable management during assembly.
