Height-Adjustable Table Power Hub with Reel Cable Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Height-adjustable tables face challenges in power cord management, leading to unsafe working conditions and restricted repositioning due to the need for multiple power cords and receptacles, which are not adaptable to changes in table height.
Innovation Solution
A height-adjustable table with an integrated electrical power hub that moves with the table, featuring a flexible electrical power distribution cable assembly allowing daisy-chaining of multiple tables, enabling independent height adjustment without disrupting power or data connectivity, and a storage compartment to manage cords and prevent tangling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a standard desktop electrical power receptacle device is plugged into an electrical receptacle at the floor with sufficient power cord length to reach the highest position of the height-adjustable table, then the power cord will pool on the floor when the height-adjustable table is lowered, but if the power cord is made short enough so as not to fall on the floor when the table is lowered, then the power cord will not be long enough to allow the height-adjustable table to be raised to maximum height
Solution Approach 1:
The power cord is made flexible and dynamically adjustable in length through a reel mechanism that allows the cord to extend and retract based on the table's height position, enabling the cord to accommodate both high and low table positions without pooling or being too short
Solution Approach 2:
A power management device with a reel mechanism serves as an intermediary between the fixed floor receptacle and the moving table, managing the power cord's deployment and retraction to ensure safe operation across all table height positions
2Reliability
If multiple height-adjustable tables each have their own electrical power receptacle device plugged into floor electrical power receptacles, then there will be a large number of power cords on the floor creating unsafe working conditions, but reducing the number of power cords limits the number of tables that can be powered
Solution Approach 1:
Multiple power receptacles are integrated into a single power management device that connects to one floor receptacle, consolidating multiple power cords into one organized connection point and reducing clutter on the floor while maintaining the ability to power multiple tables
Solution Approach 2:
The power management device serves multiple functions: it provides multiple power receptacles for different tables, manages power cord deployment, and organizes cables, allowing a single device to support multiple tables while maintaining safety
3Reliability
If power cords are plugged into electrical power receptacles in the floor and electrically connected to power receptacles on the height-adjustable table, then the height-adjustable tables cannot be re-positioned to another location within the office space
Solution Approach 1:
The power management device with a reel mechanism acts as a mobile intermediary that can be moved with the table, maintaining electrical connection while allowing the table to be repositioned to different locations within the office space
Solution Approach 2:
The power cord system is made dynamically adaptable through the reel mechanism, allowing the cord to extend and retract as the table is moved, enabling both stable electrical connection and table repositioning capability

AI summary
A height-adjustable table includes a worktop having a top surface, a bottom surface and height-adjustable legs. An electrical power center is attached to the bottom surface of the worktop and has a housing, electrical interface connectors mounted to the housing and electrically connected to each other, and an electrical power source receptacle electrically connected to the electrical interface connectors. The table has a first power cable having a first electrical interface connector electrically connected to one of the electrical interface connectors of the power center and a second electrical interface connector secured to the bottom surface of the worktop. The table includes a second power cable having a first electrical interface connector electrically connected to another of the electrical interface connectors of the power center and a second electrical interface connector secured to the bottom surface of the worktop.
