Removable Control Attachment for Safe Power Adapter Upgrades
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Homeowners face challenges in easily and safely replacing power adapters, particularly in-wall installed ones, due to the risk of electrical shock and the need for professional installation, and there is a lack of flexibility in initial placement of power adapters in new constructions, leading to costly and time-consuming changes later on.
Innovation Solution
A control attachment system that can be coupled to a power adapter, featuring contact elements, actuators, a control circuit, and a wireless communication circuit, allowing for wireless control of power and fan speed, and enabling easy modification of power adapter functionality without physical replacement, using a common interface for various control signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a power adapter is replaced to change functionality, then the desired control features can be achieved, but the installation cost and time increase due to professional installation requirements
Solution Approach 1:
The power adapter system is divided into two separable components: a fixed power adapter unit installed in the wall and a removable control attachment that can be easily swapped. This segmentation allows the control attachment to be replaced without disturbing the installed power adapter, enabling functionality changes while avoiding costly professional installation.
Solution Approach 2:
A control attachment serves as an intermediary component between the power adapter and the load. This intermediary contains the control circuitry and can be easily replaced to change functionality, while the power adapter itself remains fixed and requires no reinstallation.
2Loss of time
If a power adapter is replaced by a homeowner, then installation time and cost are reduced, but the risk of electrical shock and improper installation increases
Solution Approach 1:
By separating the power adapter from the control attachment, the system allows homeowners to safely replace only the control attachment, which does not require contact with electrical wiring. This maintains installation speed while eliminating safety risks associated with electrical work.
Solution Approach 2:
The control functionality is extracted from the power adapter into a separate control attachment. This extraction allows the control attachment to be replaced without touching electrical components, removing the safety hazard while preserving the ability to change functionality.
3Ease of manufacture
If power adapters are initially placed during new construction, then installation is convenient, but the ability to change placement later is limited due to wiring constraints
Solution Approach 1:
The system separates the fixed power adapter from the removable control attachment, allowing the control attachment to be changed or relocated independently. This enables placement flexibility after construction without requiring changes to the electrical wiring.
Solution Approach 2:
The control attachment serves as a universal interface that can be moved between different power adapter locations. This multi-functionality allows the same control attachment to work with multiple power adapters, providing flexibility in placement and configuration.
4Adaptability or versatility
If a complete power adapter is replaced to add control features, then full functionality is achieved, but the expense and complexity of installation increase
Solution Approach 1:
The system divides the power control functionality into a simple fixed power adapter and a separate control attachment containing all control features. This segmentation reduces installation complexity because only the control attachment needs to be handled, not the entire power adapter assembly.
Solution Approach 2:
The control attachment acts as an intermediary that adds control features without requiring changes to the installed power adapter. This intermediary approach provides full functionality while keeping the installation process simple and straightforward.
