Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical cables are used to connect sensors to the control system, then data transmission is reliable, but the cables are prone to damage in busy construction sites
Solution Approach 1:
The patent replaces the mechanical cable connection system with a wireless communication system. Sensors communicate with the control system via wireless signals (such as radio frequency communication), eliminating the physical cables that are susceptible to damage in construction environments. This substitution maintains data transmission reliability while removing the harmful factor of cable damage.
Solution Approach 2:
The patent introduces wireless communication signals as an intermediary medium to transmit data between sensors and the control system. Instead of direct physical connection through cables, the wireless signals act as mediators that carry information across the construction site environment without being physically exposed to damage risks.
2Loss of information
If cables are used for sensor connection, then data can be transmitted to the control system, but worker safety is compromised
Solution Approach 1:
The patent replaces the mechanical cable system with wireless communication technology. Sensors mounted on construction equipment transmit data wirelessly to the control system, eliminating cables that could entangle or endanger workers. This maintains full data transmission capability while removing the safety hazard posed by physical cables in the work area.
3Object-affected harmful factors
If sensors are placed far from the machine body, then cable damage risk is reduced, but cable length and complexity increase
Solution Approach 1:
The patent replaces the mechanical cable system with wireless communication, allowing sensors to be placed at optimal locations for measurement without concern for cable routing. Sensors can be positioned far from the machine body or in difficult-to-reach areas without increasing system complexity, as wireless signals naturally traverse the space without physical constraints.
