Charging Base Housing with Keyed Adapter Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing charging systems for electronic devices require users to insert cords, which can be costly and pose safety risks, especially in environments where devices are used by inmates who can reset security features, and they lack protection against unauthorized access and device damage.
Innovation Solution
A charging system that uses a housing and charging base with retention arms to align and secure a charging adapter within the device, eliminating the need for cords and providing a protective housing that prevents incorrect orientation and unauthorized access, utilizing a keyed design to ensure proper charging and secure device positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional cords are used for charging, then charging function is provided, but cost increases and safety risks arise
Solution Approach 1:
The patent extracts the charging function from the traditional cord-and-port interface and relocates it to a fixed charging station with integrated contacts. The charging contacts are built into the station and housing, eliminating the need for removable cords that can be misused or damaged.
Solution Approach 2:
The patent merges the charging function with the housing and charging station structure. The charging contacts are integrated into the station and housing components, creating a unified system where charging occurs through direct contact when the device is placed in the housing, rather than requiring separate cord connections.
2Ease of operation
If housing provides full access to device, then ease of use is improved, but unauthorized access and security feature disabling occur
Solution Approach 1:
The housing provides selective access to different parts of the device. It allows access to the charging port area while blocking access to security-sensitive areas such as buttons and inputs that could disable security features. This localized access control maintains both usability and security.
Solution Approach 2:
The housing acts as an intermediary between the user and the device. It mediates access by providing controlled openings for necessary functions while blocking access to sensitive areas, thus protecting security features without completely preventing device use.
3Ease of operation
If device can be inserted in any orientation, then ease of insertion is improved, but incorrect charging orientation occurs
Solution Approach 1:
The housing and charging station incorporate asymmetric features such as angled surfaces, offset contacts, or directional guides that only allow the device to be inserted in the correct orientation. These asymmetric design elements prevent incorrect insertion while maintaining ease of use through intuitive alignment.
4Reliability
If cord-based charging is used, then charging function is provided, but device complexity and cost increase
Solution Approach 1:
The patent extracts the cord component from the charging system and replaces it with fixed charging contacts integrated into the housing and station. This eliminates the need for separate cords, ports, and associated connection mechanisms, thereby reducing overall system complexity.

AI summary
The charging system charges electronic devices through the use of a charging base. Charging contacts within the charging base contact a charging adapter inserted into a port of the electronic device. The charging contacts of the charging base contact the charging contacts of the charging adapter to charge the device. A housing that partially encloses the electronic device limits the orientations in which the device can be inserted into the charging base. The housing promotes inserting the device into the charging base in a charging orientation that will charge the device.
