Solution Overview
Problem
Lunar regolith dust poses significant operational challenges due to its abrasive nature and tendency to accumulate, damaging machinery and causing respiratory hazards, and existing methods are inadequate for effectively managing it during lunar rover operations.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the rover moves across the lunar surface, then it can perform scientific operations and traverse terrain, but lunar regolith dust is thrown up and accumulates, causing abrasive damage and respiratory hazards
Solution Approach 1:
The system performs preliminary sintering of lunar regolith particles before the rover reaches them. The emitter array is positioned ahead of the rover and activates in advance to fuse particles into a dust-free path, preventing dust generation before the rover's wheels encounter the terrain.
Solution Approach 2:
The system converts the harmful abrasive lunar regolith particles into a beneficial sintered surface. By applying electromagnetic radiation to heat and fuse the particles, the原本 harmful loose dust is transformed into a stable, dust-free pathway that protects the rover from abrasive damage.
2Object-affected harmful factors
If the emitter array is activated to sinter regolith particles, then dust generation is reduced, but energy consumption increases
Solution Approach 1:
The system uses detector elements to continuously monitor the lunar surface for the presence and density of regolith particles. This feedback information is fed to the controller, which activates the emitter array only when particles are detected above a threshold level, and adjusts power accordingly, preventing unnecessary energy consumption when dust is not present.
Solution Approach 2:
The system dynamically changes the operational parameters of the emitter array based on real-time conditions. The controller adjusts the power level and activation state of the emitters according to the detected particle density, using higher power only when necessary to sinter dense particle regions and lower or zero power when particle levels are low.
3Reliability
If the emitter array continuously sinters regolith, then dust-free paths are maintained, but the device complexity and system cost increase
Solution Approach 1:
The emitter array is divided into multiple independent emitter elements that can be individually controlled. This segmentation allows the system to target specific regions with dust particles rather than activating the entire array, reducing complexity and energy consumption while maintaining effective dust suppression where needed.
Solution Approach 2:
The system uses the rover's own motion and the natural distribution of lunar particles to guide the sintering process. As the rover moves forward, the detector continuously scans the path ahead, and the emitter array automatically activates only in regions where particles are present, making the system self-regulating and reducing the need for complex external control mechanisms.
