Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional jet grouting machines are used on muddy and uneven roads, then the construction can proceed, but the travel of shotcrete vehicles is greatly affected and construction progress is seriously hindered
Solution Approach 1:
The patent replaces the conventional wheeled mechanical system with a track-based system. The track-type jet grouting machine uses tracked chassis instead of wheels, providing superior traction and mobility on muddy and uneven terrain. This mechanical substitution enables the equipment to operate in harsh environments without compromising construction progress.
2Adaptability or versatility
If multiple dedicated vehicles are used for jet grouting, then the grouting materials can be transported and stored, but the working environment becomes very harsh and the system complexity increases
Solution Approach 1:
The patent merges multiple previously separate functions into a single integrated vehicle. The track-type jet grouting machine combines material storage (with storage bins), mixing (with proportioning equipment), and grouting injection functions in one unified platform. This eliminates the need for multiple dedicated vehicles while maintaining full operational capability.
Solution Approach 2:
The integrated vehicle performs multiple functions simultaneously - it can transport grouting materials, store materials in dedicated bins, proportion the two-component polymer materials, and inject them through the jet grouting system. This multi-functional design reduces the number of vehicles needed while increasing adaptability to different construction requirements.
3Productivity
If manual feeding of grouting materials is used, then the system is simple to operate, but the working efficiency is low due to manual labor limitations
Solution Approach 1:
The system incorporates automatic material feeding mechanisms that eliminate or reduce manual labor. The proportioning equipment automatically measures and feeds the two-component polymer materials from the storage bins, and the pump system automatically transfers and injects the mixed grout. This self-service capability significantly improves working efficiency while reducing dependence on manual labor.
