Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wall plug power supplies are used, then the device is light in weight and simple in structure, but it fails to provide power during outages leading to device downtime
Solution Approach 1:
The patent combines a traditional wall plug power supply with UPS functionality into a single integrated device. The wall plug adapter incorporates both AC-DC conversion circuitry and DC-AC inversion circuitry, allowing it to function as both a normal power supply and an uninterruptible power supply during outages.
Solution Approach 2:
The wall plug adapter is designed to perform multiple functions: it serves as a standard AC-DC power converter during normal operation, and simultaneously functions as a DC-AC inverter during power outages to provide backup power. This multi-functionality eliminates the need for separate UPS equipment.
2Reliability
If large UPS devices are deployed to provide backup power, then power continuity is ensured, but the device occupies excessive space and creates safety hazards
Solution Approach 1:
The patent embeds the UPS functionality within the existing wall plug adapter structure. The battery, inverter circuitry, and control components are nested inside the compact adapter housing, utilizing the available internal space efficiently. This nesting approach enables backup power capability without requiring additional external equipment.
Solution Approach 2:
The invention transitions from floor-standing or wall-mounted UPS units to a plug-in format that utilizes the vertical dimension of the electrical outlet. By plugging into the wall outlet, the device occupies minimal horizontal space while providing backup power through the integrated battery and inverter systems.
3Force
If the blade tension lever increases the distance between blades, then contact tension with the outlet is improved, but the structural complexity of the plug increases
Solution Approach 1:
The blade tension lever is designed to be automatically actuated by the insertion process itself. As the plug is inserted into the outlet, the blades naturally engage with the outlet contacts, and the tension lever automatically adjusts to provide optimal contact pressure without requiring manual adjustment or additional actuation mechanisms.

AI summary
A wall plug uninterruptible power supply (UPS) for providing backup power is disclosed. The wall plug uninterruptible power supply may include a plug, an enclosure, electronic components, and a power receptacle. The wall plug uninterruptible power supply may be configured to provide power (e.g., backup power) even when the plug does not receive any power, thereby bridging a power gap of time. For example, the bridge of power may occur at a time between when power is lost (e.g., utility power outage) to a time when power is restored or alternative power is provided by a secondary source such as a backup generator.
