Solution Overview
Problem
Conventional wireless charging stations for portable electronic devices, such as robots, often occupy valuable space and are prone to being knocked over, limiting their usability due to their placement on the floor and requiring dedicated space for operation.
Innovation Solution
An electronic device with a detachable housing, a light generator for guiding external devices, and a power transmission circuit that wirelessly transmits power once the external device is positioned correctly, allowing for efficient charging without the need for dedicated charging stations and maximizing space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If charging stations are placed on the floor for wireless charging, then wireless charging functionality is provided, but valuable floor space is occupied and the charging station is prone to being knocked over
Solution Approach 1:
The charging station is nested within the lower empty space of another pre-placed electronic device (such as a TV or refrigerator). The housing is detachably coupled to the host device, allowing the charging station to utilize the unused space inside or below the host device, thereby providing wireless charging functionality without occupying additional floor space.
2Adaptability or versatility
If charging stations are placed on the floor, then wireless charging is enabled, but the charging station is highly likely to be hit while walking on the floor
Solution Approach 1:
By nesting the charging station within the lower empty space of a stable host device, the charging station is positioned in a location that is not in the path of normal foot traffic. This eliminates the risk of being knocked over while walking, as the charging station is now protected within the host device's structure rather than being exposed on the floor.
3Reliability
If dedicated space is allocated for charging stations, then wireless charging operation is ensured, but living space is limited
Solution Approach 1:
The charging station utilizes the lower empty space of the host device, which would otherwise be unused. This nesting approach ensures that wireless charging operation is maintained while maximizing the utilization of available space, thereby not limiting living space.
Solution Approach 2:
The host device serves multiple functions: its primary function and additionally houses the charging station in its lower empty space. This multi-functionality allows the same physical space to serve both the host device's purpose and the wireless charging function, eliminating the need for dedicated charging space.
4Productivity
If external electronic devices automatically move to charging position, then wireless power transmission efficiency is improved, but additional positioning control systems are required
Solution Approach 1:
The patent replaces complex mechanical positioning control systems with a simpler optical guidance system. A light generator emits light to indicate the charging position, and the external electronic device uses a light receiver to detect the light and automatically move to the correct position. This substitution significantly reduces system complexity while maintaining automatic positioning capability and power transmission efficiency.
