Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If lead-acid batteries are used to power mobile X-ray apparatus, then the apparatus can be moved between facilities, but the charging time becomes excessively long (5-7 hours)
Solution Approach 1:
The patent changes the chemical composition and electrical parameters of the energy storage device from lead-acid battery to lithium-ion battery, achieving a transition from 5-7 hour charging times to approximately 1 hour charging times, while increasing energy density and autonomous operation capability
Solution Approach 2:
The patent divides the energy storage system into two electrically separate regions: a first region (lithium-ion battery) dedicated to powering the X-ray source with high current capability, and a second region for system power supply, allowing independent optimization of each function
2Power
If condenser units are used for current storage, then high amperage can be provided for X-ray imaging, but the storage capacity becomes very limited
Solution Approach 1:
The patent transitions from condenser-based energy storage to lithium-ion battery technology, changing the fundamental parameters of energy density and storage capacity while maintaining the ability to deliver high currents required for X-ray source operation
Solution Approach 2:
The patent creates a dedicated first energy storage region optimized specifically for X-ray source power delivery, separating it from the general system power supply, thereby ensuring sufficient energy capacity for imaging operations
3Duration of action of stationary object
If power cable connections are used to supply electrical energy, then continuous operation can be maintained, but the cables become obstructive and safety hazards in confined areas
Solution Approach 1:
The patent extracts the power supply dependency from the mobile X-ray apparatus by equipping it with an autonomous lithium-ion battery system, eliminating the need for trailing power cables and enabling truly cable-free operation in confined hospital areas
Solution Approach 2:
The patent changes the energy supply mode from external grid connection via cable to internal autonomous battery power, fundamentally altering how the apparatus obtains and uses electrical energy
