Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If precise alignment between charging contact point and charging contact plate is required, then charging reliability is improved, but device complexity and cost increase due to multiple sensors and complex path configuration
Solution Approach 1:
The patent replaces the mechanical contact-based charging system with a wireless electromagnetic field-based charging system. The base station transmits electromagnetic signals that directly charge the mobile device without requiring physical contact or precise alignment between charging contacts, thereby eliminating the need for complex sensor systems while maintaining charging reliability
Solution Approach 2:
The patent introduces electromagnetic fields as an intermediary between the base station and mobile device for energy transfer. Instead of direct mechanical contact, the electromagnetic field serves as the medium to transmit charging energy, enabling charging without precise alignment and reducing system complexity
2Reliability
If precise alignment and complex sensor systems are used for charging, then charging reliability is improved, but time consumed increases and productivity decreases
Solution Approach 1:
By replacing mechanical contact alignment with wireless electromagnetic charging, the system eliminates the time required for precise positioning and sensor-based path configuration, significantly reducing charging time and improving operational efficiency while maintaining charging success rate
Solution Approach 2:
The base station continuously maintains electromagnetic charging fields ready for immediate energy transfer. When the mobile device enters the charging range, charging can begin immediately without requiring time-consuming alignment procedures, thereby improving productivity
3Use of energy by moving object
If autonomous mobile device returns to charging station for charging, then power supply is maintained, but operational time is lost and efficiency is reduced
Solution Approach 1:
The wireless charging system enables continuous charging operation while the mobile device remains in its working position. The electromagnetic field continuously transfers energy to the device without requiring it to return to a charging station, eliminating charging downtime and maintaining operational continuity
Solution Approach 2:
The electromagnetic field acts as an intermediary that enables energy transfer across space without requiring the mobile device to physically relocate to a charging station, allowing charging to occur in situ and eliminating loss of operational time
