Plug-In Wall Transformer With Removable Securement Tab
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The varying regulations regarding the securement of plug-in wall transformers across different jurisdictions force manufacturers to produce two versions of identical transformers, one with and one without a securement mechanism, to comply with local laws.
Innovation Solution
A high-level adaptable plug-in transformer design that includes a securement tab and slot configuration, allowing the transformer to be optionally secured to a wall outlet through a screw aperture, thus accommodating jurisdictions with different securement requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a securement mechanism is added to the transformer, then the transformer can be secured to the wall outlet to prevent accidental dislodging, but the transformer cannot be easily unplugged when necessary
Solution Approach 1:
The securement tab is designed to be removable from the slot, allowing the transformer to dynamically switch between secured and unsecured states. The tab can be inserted into the slot to engage with the outlet for securement, or removed to allow easy unplugging, thus providing dynamic adaptability to different operational requirements
2Adaptability or versatility
If a securement mechanism is included in the transformer design, then jurisdictions requiring securement can use it, but jurisdictions prohibiting securement cannot use the same design
Solution Approach 1:
The transformer is designed with a universal securement system where the securement tab and slot configuration allows the same transformer model to function in both secured and non-secured modes. This multi-functional design eliminates the need for separate transformer versions for different jurisdictions, as the securement tab can be easily installed or removed based on regulatory requirements
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The adaptable design allows a single transformer model to comply with both jurisdictions that require and those that prohibit the securement of transformers to the wall outlet, reducing manufacturing complexity and inventory needs.
Implementation Method 1
the inserted tab is retained within the slot by frictional forces between the tab and the walls of the slot

AI summary
An adaptable plug-in transformer includes a housing having a slot for receiving a securement tab, with the securement tab having an aperture therethrough for receiving a screw to allow attaching and securing the transformer to a wall outlet. The adaptable plug-in transformer thus may be used both in jurisdictions which require attachment or securement of plug-in transformers, and in jurisdictions which prohibit attachment or securement of plug-in transformers.
