Height Adjustable Charging Grommet
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing desks and tabletops face challenges in accommodating multiple sized cables and providing a wireless charging surface while maintaining ease of use and organization, with most apertures positioned far from the seating area.
Innovation Solution
A height adjustable charging grommet that allows multiple sized cables to be fed through a desk aperture, featuring a grommet sleeve with longitudinally extending channels and a removable grommet cap that can be positioned at varying vertical heights, providing a wireless charging surface that can be moved closer to the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed aperture position is used for cable feeding, then the desk structure is simple, but the charging surface cannot be repositioned for user convenience
Solution Approach 1:
The grommet cap is made movable along the grommet body, allowing it to transition between fixed and movable states. This enables the charging surface to be repositioned vertically along the aperture, providing user convenience while maintaining a relatively simple overall structure.
Solution Approach 2:
The grommet is divided into separate components: a grommet body fixed in the aperture and a movable grommet cap. This segmentation allows the cap to be independently positioned along the body, enabling flexible charging surface placement without complicating the entire desk structure.
2Adaptability or versatility
If multiple sized cables are accommodated through a single aperture, then cable connectivity is improved, but cable organization becomes difficult
Solution Approach 1:
The grommet cap features a localized cutout region that can be selectively opened or closed. This allows users to expose only the specific cable size needed at any given time, improving cable organization while maintaining the ability to accommodate multiple cable sizes when required.
3Ease of operation
If the charging surface is fixed at the aperture location, then the structure is simple, but the charging position cannot be optimized for user convenience
Solution Approach 1:
The grommet cap is designed to move vertically along the grommet body, transforming the static charging surface into a dynamic one. Users can adjust the charging surface height to optimal positions while the underlying structure remains relatively simple.
Solution Approach 2:
The grommet cap acts as an intermediary component between the fixed grommet body and the charging surface. It provides the height adjustment functionality without requiring complex mechanisms, serving as a simple mediator that enables position optimization.

AI summary
A height adjustable charging grommet can include a grommet sleeve and a grommet cap. The grommet cap can include a charging surface and one or more legs. The grommet sleeve can include one or more longitudinal channels on an inner portion of a sleeve wall. One or more of the legs of the grommet cap can fit within the longitudinal channels. One or more of the longitudinal channels include a respective floor tab. The floor tabs can be positioned at different heights relative to one another.
