Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the e-vaping device is stored in a personal charging case, then the device can be protected and charged, but the device requires manual disassembly and checking which disrupts the vaping experience
Solution Approach 1:
The e-vaping device is configured to automatically engage with the charging case without manual disassembly or intervention. The device autonomously establishes electrical contact for charging when placed in the case, eliminating the need for users to manually check or assemble components, thus maintaining continuous charging while preserving user convenience
Solution Approach 2:
The charging case pre-positions electrical contacts and charging circuits in advance within the case structure. When the e-vaping device is inserted, the charging connection is immediately established without requiring any additional user actions, ensuring continuous charging readiness while maintaining ease of operation
2Loss of information
If the charging case provides real-time status updates, then user awareness of device state is improved, but the device complexity increases
Solution Approach 1:
The charging case incorporates light indicators that provide real-time visual feedback on battery charge levels and device status. This feedback mechanism informs users of the device state without requiring complex digital displays or additional electronics in the e-vaping device itself, thus improving status awareness while minimizing the increase in overall system complexity
Solution Approach 2:
The charging case uses different colored lights to indicate various charge levels and operational states of the e-vaping device. This color-coded status indication system provides comprehensive information to users through simple visual cues, avoiding the need for complex text-based displays or additional sensors, thereby improving status awareness without significantly increasing device complexity

Implementation Method 1
a spring element positioned within the body interior, the spring element being configured to exert a spring force on the e-vaping device to push the e-vaping device electrical connection away from contact with the ECC electrical connection
Implementation Method 2
a cover configured to exert the holding force on the e-vaping device, based on the cover completing the enclosure of the e-vaping device within the PCC, the holding force being greater than the spring force such that the cover pushes the e-vaping device electrical connection into contact with the ECC electrical connection
Implementation Method 3
an e-vaping device charge light indicator, the e-vaping device charge light indicator being configured to emit light at a selected one of a plurality of color temperatures based on a charge level of the e-vaping device internal battery

AI summary
A personal charging case (100) for charging an e-vaping device includes a body (101) to establish a partial enclosure of the e-vaping device, an electrical charging circuit (130), and a spring element (120). The electrical charging circuit (130) includes an electrical connection (122) within the body interior and may charge the e-vaping device internal battery via contact with an electrical connection of the e-vaping device. The spring element (120) exerts a spring force on the e-vaping device to push the e-vaping device electrical connection away from contact with the electrical charging circuit electrical connection (122) in the absence of a holding force. The case (100) may include a cover that exerts the holding force on the e-vaping device to push the e-vaping device electrical connection into contact with the electrical charging circuit electrical connection (122). The case may include one or more light indicators (128) to indicate amounts of electrical power and pre-vapor formulation in the e-vaping device.
