Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Audience measurement entities face challenges in accurately collecting media monitoring information due to the potential removal of power from metering devices, which can disrupt data collection and impact the quality of measurement reports.
Innovation Solution
A plug retainer apparatus that secures power cords to electrical outlets, preventing inadvertent removal and allowing for quick release without tools, while accommodating different sizes and shapes, and preventing damage to outlet covers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a plug retainer apparatus is used to secure power cords to electrical outlets, then the reliability of continuous power supply is improved, but the device complexity increases
Solution Approach 1:
The plug retainer apparatus is divided into separate functional components: a retainer body that mounts to the outlet, a power cord engagement mechanism, and a release mechanism. This segmentation allows each component to perform its specific function efficiently while simplifying the overall design and assembly process.
Solution Approach 2:
The apparatus incorporates a self-locking mechanism where the power cord engagement automatically secures the cord when inserted, and a simple manual release mechanism that allows quick removal without tools. The design uses the cord's own insertion motion to trigger the locking action, eliminating the need for separate fastening operations.
2Adaptability or versatility
If a plug retainer apparatus is designed to accommodate different sizes and shapes of power cords, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The retainer body is designed with a universal mounting interface that attaches to standard electrical outlets, while the engagement mechanism features adjustable or flexible elements that can accommodate various power cord diameters and connector shapes. This allows a single apparatus design to serve multiple cord types without requiring multiple specialized components.
Solution Approach 2:
The apparatus incorporates flexible or adjustable engagement elements whose dimensions or configuration can vary to match different power cord parameters. This may include flexible arms, adjustable clamps, or elastic components that adapt their geometry to securely hold cords of different sizes and shapes within the same retainer structure.
3Object-affected harmful factors
If a plug retainer apparatus is designed to prevent damage to outlet covers, then the object-affected harmful factors are reduced, but the ease of operation is worsened
Solution Approach 1:
The apparatus introduces a protective intermediary structure between the power cord removal force and the outlet cover. This retainer body absorbs and redirects removal forces through its mounting mechanism and structural design, preventing direct transmission of damaging forces to the outlet cover while still allowing controlled cord removal through the release mechanism.
Solution Approach 2:
The design replaces direct mechanical force transmission to the outlet cover with an alternative release mechanism that uses leverage, cam action, or elastic release to disengage the power cord. This substitution allows cord removal through a controlled mechanical advantage system rather than direct pulling on the outlet structure.

AI summary
A retainer apparatus includes a post having a first end to be received by an opening of a wall plate cover of an outlet and a second end opposite the first end. At least a portion of the post has a plurality of grooves positioned between the first end and the second end. The plurality of grooves forming a retainer-receiving portion. A plug retainer is moveably coupled to the post. The plug retainer to slide along the retainer-receiving portion in a linear direction relative to the grooves when the plug retainer is moved relative to the retainer-receiving portion of the post.
