Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft tables lack a convenient and safe method for charging electronic devices while maintaining the ability to stow the table when not in use.
Innovation Solution
A fold-out side ledge wireless charging table for aircraft that automatically disconnects power when stowed, utilizing a bearing block with spring contacts to establish and break electrical connections based on the table's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the table is made maneuverable between stowed and deployed positions, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The table leaf support is designed to be maneuverable between stowed and deployed positions, transforming a static structure into a dynamic one that adapts to different operational states. This allows the table to be easily deployed when needed and stowed when not in use, improving ease of operation while managing complexity through controlled movement mechanisms
2Productivity
If power is continuously supplied to the power unit, then the productivity is improved, but the loss of energy increases
Solution Approach 1:
The electrical connection between the power source and power unit is established periodically based on the table's position - connected when deployed and disconnected when stowed. This periodic connection ensures power is supplied only when the charging function is needed, maintaining productivity while eliminating continuous energy loss during stowed periods
3Adaptability or versatility
If the table provides wireless charging functionality, then the adaptability is improved, but the object-generated harmful factors increase
Solution Approach 1:
The table leaf support acts as an intermediary mechanism that controls the electrical connection between the power source and power unit. Through this intermediary, the system automatically establishes or breaks electrical connections based on whether the table is deployed or stowed, enabling wireless charging functionality while mitigating electrical hazards through automatic disconnection
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

AI summary
A wireless charging table for use in an aircraft includes a frame assembly for mounting the wireless charging table within the aircraft; a table leaf support coupled to the frame assembly and maneuverable between a stowed position and a deployed position; a main table leaf mounted to the table leaf support and having a power unit; and an electrical system to provide power to the power unit when the table leaf support is in the deployed position. When the table leaf support is in the deployed position, an electrical connection is established between a power source and the power unit, and when the table leaf support is in the stowed position, the electrical connection is broken between the power source and the power unit. The power unit is to provide wireless charging to one or more devices when the electrical connection is established.
