Mobile device support base including power interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional modular furniture equipment support bases are prone to blockages and safety hazards due to exposed connecting holes or slots, which can lead to damage or electrical risks when detachable accessories are not connected, especially posing risks to small children and potential electrical shorts.
Innovation Solution
A modular furniture support base with a connector hub and power interface set, featuring a cover plate to prevent debris entry and a baffle mechanism with springs to secure the detachable accessory, ensuring safe and reliable physical and electrical connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the connecting hole or slot is exposed to allow easy insertion of detachable accessories, then the ease of operation is improved, but foreign materials and debris can enter and block the connection, worsening the reliability
Solution Approach 1:
A cover plate is provided that can be positioned over the connecting hole or slot before the detachable accessory is inserted. The cover plate prevents foreign materials from entering the connection area during periods when no accessory is attached, while still allowing easy access when needed.
Solution Approach 2:
The cover plate is made movable between a first position covering the connecting hole/slot and a second position exposing it. This dynamic configuration allows the system to switch between protecting the connection (when no accessory is attached) and allowing insertion (when accessory needs to be connected).
2Strength
If the connecting hole is designed to strongly retain inserted pieces for secure connection, then the strength of connection is improved, but it creates a safety hazard for small children's fingers, worsening the safety
Solution Approach 1:
The cover plate is positioned in advance to cover the connecting hole or slot, preventing children's fingers from accessing the strong retention mechanism. The cover plate acts as a protective barrier that eliminates the safety hazard while maintaining the strong connection capability when accessories are properly installed.
3Adaptability or versatility
If power connections are exposed to provide electrical connectivity, then the adaptability is improved, but electrical shorts and fire risks increase due to foreign materials, worsening the safety
Solution Approach 1:
The cover plate is positioned to cover the power connections before any foreign materials can enter the area. This preliminary protective action prevents debris from causing electrical shorts while still allowing electrical connectivity to be established when accessories are properly connected.
Solution Approach 2:
The cover plate serves as an intermediary element between the external environment and the exposed power connections. It mediates by providing physical protection against foreign materials that could cause electrical hazards, while still permitting legitimate electrical connections to be made.
4Object-affected harmful factors
If the cover plate fully covers the connector hub to prevent debris entry, then the protection against foreign materials is improved, but the ability to access power connections is reduced, worsening the ease of operation
Solution Approach 1:
The cover plate is designed to be movable between a closed position that provides full protection and an open position that exposes the power connections. This dynamic design allows the system to switch between maximum protection and maximum accessibility based on operational needs.
Solution Approach 2:
The cover plate can be configured to provide different levels of coverage - fully covering non-functional areas while leaving power connection areas accessible. This local differentiation allows protection where needed while maintaining accessibility where required.

AI summary
A support base includes a connector hub having a top end, a bottom end spaced apart from the top end, and a chamber wall extending between the top and bottom ends. The chamber wall defines a chamber within the connector hub. A power interface set may be positioned in the chamber. The power interface set is dimensioned such that an annular support gap is formed between the power interface set and the chamber wall. A cover plate may be coupled to the top end of the connector hub.
