Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a homeowner replaces an in-wall power adapter, then the power adapter functionality can be updated or improved, but the installation cost and safety risk increase due to professional installation requirements
Solution Approach 1:
The power adapter is divided into two separate components: a permanent in-wall unit and a removable control attachment. The control attachment contains the functional elements (switches, dimmers, timers) that can be easily replaced by homeowners without touching the electrical wiring. This segmentation allows functionality updates while maintaining safe, low-cost installation of the permanent portion.
Solution Approach 2:
The control functionality is extracted from the in-wall power adapter and placed into a separate removable control attachment. This extracted control attachment can be easily removed and replaced by homeowners without requiring electrical expertise, while the permanent in-wall unit remains simple and safe to install.
2Productivity
If an in-wall power adapter is installed during new construction, then power control functionality is available, but the ability to adapt to different functional needs after construction is limited
Solution Approach 1:
The system transitions from a static, fixed power adapter to a dynamic configuration where the control attachment can be easily swapped. This allows the power control functionality to adapt to changing user needs after construction without requiring reinstallation of the entire device. The removable control attachment enables the system to evolve with technology advances and user preferences.
Solution Approach 2:
The in-wall power adapter is designed with a universal interface that can accommodate different types of control attachments. This universality allows a single permanent installation to support multiple functional configurations (standard switches, dimmers, timers, smart controls) depending on which control attachment is installed, providing post-construction adaptability.
3Ease of manufacture
If a homeowner attempts to install a power adapter without professional help, then installation cost is reduced, but the risk of shock or improper installation increases
Solution Approach 1:
The complex control functionality is extracted into a removable attachment that requires no electrical installation. Homeowners only need to connect simple, pre-wired control attachments to the in-wall unit, eliminating the need to work with exposed electrical wires and significantly reducing safety risks while maintaining low installation costs.
4Adaptability or versatility
If the entire power adapter is replaced to update functionality, then the latest features are available, but the time and effort required for replacement increases
Solution Approach 1:
By segmenting the power adapter into a permanent in-wall unit and a removable control attachment, the system allows users to update only the control attachment portion when new features are desired. This eliminates the time-consuming process of replacing the entire power adapter, including electrical disconnection and reconnection, while still providing access to the latest control features.
