Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional concrete constructions are used, then structural strength and stability are achieved, but construction costs increase and environmental impact worsens due to high CO2 emissions
Solution Approach 1:
The patent changes the material composition parameters by replacing concrete with a mixture of stone fractions (5-50mm), binding agents (5-15% by weight), and water (65-80% by weight). This parameter change maintains structural strength while eliminating the high CO2 emissions associated with concrete production.
Solution Approach 2:
The patent uses composite materials by combining stone fractions of different sizes (5mm, 10mm, 20mm, 50mm) with binding agents to create a new construction material that replaces concrete. This composite approach achieves structural integrity without the environmental harm of conventional concrete.
2Stability of the object's composition
If concrete constructions are built, then foundation stability is achieved, but construction complexity and costs increase due to specialized foundation requirements
Solution Approach 1:
The patent changes the weight and density parameters of the construction material by using stone fractions with binding agents instead of heavy concrete. This allows the structure to be built on normal soil ground without requiring solid foundations, reducing foundation complexity while maintaining stability.
3Extent of automation
If robots are used to construct jammed architectural structures, then construction automation is achieved, but device size and noise level increase limiting application scenarios
Solution Approach 1:
The patent segments the construction process into simple, repetitive tasks that can be performed by smaller, less complex robotic units. The modular nature of placing individual stone fractions allows automation without requiring large, noisy construction robots, enabling use in residential and confined spaces.
4Strength
If concrete constructions are built, then structural integrity is achieved, but reusability and recyclability worsen as components cannot be directly reused
Solution Approach 1:
The patent enables recovery and reuse of stone fractions after disassembly. Unlike concrete that must be recycled, the stone fractions can be cleaned of binding agent residues and reused in new constructions, maintaining structural integrity while improving reusability and reducing waste.
5Manufacturing precision
If marking device with sensor wire is used, then construction precision and flexibility are improved, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical measurement and positioning systems with a simple sensor wire that emits detectable signals. The robotic system uses optical or electromagnetic sensors to detect the wire's position, substituting mechanical complexity with field-based detection while maintaining high construction precision.
