Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If primary batteries are used to power the telemetry system, then the system can provide sufficient power, but the cost and environmental hazard increase significantly
Solution Approach 1:
The patent implements a rechargeable battery system that can be recharged multiple times, eliminating the need to discard batteries after single use. The controller manages charging cycles and monitors battery status, enabling recovery and reuse of the energy storage device, thereby reducing environmental hazard while maintaining sufficient power output.
Solution Approach 2:
The patent replaces the traditional mechanical generator system with an electrical rechargeable battery system. This substitution eliminates moving parts that cause friction and failure, providing reliable power without the mechanical complexity and environmental hazards of disposable batteries or mechanical generators.
2Ease of manufacture
If an electrical generator is used to power the telemetry system, then the system can operate without batteries, but the generator often fails due to friction and does not provide enough power in small diameter drilling applications
Solution Approach 1:
The patent replaces the mechanical generator system with an electrical rechargeable battery system. This substitution eliminates moving parts that cause friction and failure, providing reliable power without the mechanical complexity and environmental hazards of disposable batteries or mechanical generators.
Solution Approach 2:
The patent changes the power delivery parameters by using a rechargeable battery system that can be controlled electronically. The controller manages charge and discharge rates, voltage, and current to optimize performance for small diameter drilling applications, providing sufficient power without the mechanical limitations of generators.
3Power
If a generator is used in under-balanced drilling situations, then power can be provided, but the system becomes difficult and impractical to operate during tripping
Solution Approach 1:
The patent replaces the mechanical generator system with an electrical rechargeable battery system. This substitution eliminates moving parts that cause friction and failure, providing reliable power without the mechanical complexity and environmental hazards of disposable batteries or mechanical generators.
Solution Approach 2:
The rechargeable battery system provides power independently of the drilling operation status. The controller automatically manages charging and discharging based on battery status and power demands, eliminating the need for manual operation or external power sources during tripping or other drilling operations.
4Device complexity
If disposable batteries are used, then the system is simple to implement, but the disposal cost and environmental impact increase
Solution Approach 1:
The patent implements a rechargeable battery system that can be recharged multiple times, eliminating the need to discard batteries after single use. The controller manages charging cycles and monitors battery status, enabling recovery and reuse of the energy storage device, thereby reducing environmental hazard while maintaining sufficient power output.
Solution Approach 2:
The patent replaces the traditional mechanical generator system with an electrical rechargeable battery system. This substitution eliminates moving parts that cause friction and failure, providing reliable power without the mechanical complexity and environmental hazards of disposable batteries or mechanical generators.
