Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the LiDAR device uses fixed light-emitting channels that cannot be adjusted after installation, then the device structure is simple and stable, but the adaptability to new requirements deteriorates
Solution Approach 1:
The LiDAR device is divided into a rear-end component (including optical units and control circuits) and detachable front-end components (including lenses and optical interfaces). This segmentation allows the front-end components to be replaced to adapt to different requirements without redesigning the entire device, thus improving adaptability while maintaining structural simplicity through modular design.
Solution Approach 2:
The patent introduces detachable front-end components that can be coupled and decoupled from the rear-end component. This dynamic configuration allows the device to change its optical characteristics (field of view, light emission angle, channel spacing) by simply attaching different front-end components, providing adaptability without increasing overall device complexity.
2Adaptability or versatility
If the LiDAR device uses fixed light-emitting channels, then the manufacturing and installation process is simple, but the flexibility to adjust field of view, light emission angle, and channel spacing deteriorates
Solution Approach 1:
By segmenting the device into standardized rear-end and front-end components with detachable interfaces, the manufacturing process remains simple for each module while the assembly becomes flexible. The rear-end component can be manufactured once and reused, while different front-end components can be produced to meet various field of view and spacing requirements.
Solution Approach 2:
The rear-end component is designed as a universal platform that can work with multiple types of front-end components. The standardized interface and coupling mechanism allow a single rear-end component to support multiple configurations of field of view, light emission angles, and channel spacing, achieving multi-functionality without complicating the core manufacturing process.
3Productivity
If the LiDAR device requires redesign for new requirements, then the device can be optimized for specific applications, but the time investment for redesign increases
Solution Approach 1:
The patent anticipates future requirements by designing a platform with detachable front-end components that can be pre-configured for different applications. When new requirements arise, pre-designed front-end components can be selected and attached without starting the redesign process from scratch, significantly reducing the time investment while still allowing optimization for specific applications.
Solution Approach 2:
The dynamic, detachable architecture allows the device to be quickly reconfigured for new applications by simply changing front-end components rather than undertaking comprehensive redesigns. This enables rapid response to new requirements while maintaining the ability to optimize performance for specific use cases through component selection.
