Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for adaptable and convenient charging solutions for electronic devices that can be used in various locations, including furniture, and that accommodate wireless charging without requiring precise device placement, and that are not limited by the length of charging cables.
Innovation Solution
A cassette shelf mechanism with a mounting plate, trolley, rotary hinge, pivot hinge, and extension tensioning module, allowing the shelf to unfold and move along multiple axes for flexible positioning and wireless charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wireless charging induction coil is stationary, then the charging location is fixed, but the charging area is small and the user must be careful when placing the electronic device in the appropriate charging area
Solution Approach 1:
The patent applies the dynamics principle by making the charging shelf movable instead of stationary. The shelf can be extended and repositioned to different locations, allowing the wireless charging coil to dynamically adjust its position. This resolves the contradiction by maintaining a fixed charging area while expanding the usable charging space through movement, eliminating the need for users to precisely place devices in a small static zone.
Solution Approach 2:
The patent introduces dimensional flexibility by allowing the charging shelf to move along multiple axes (X, Y, Z directions) and rotate around axes. This transforms a two-dimensional charging surface into a three-dimensionally adjustable structure, effectively expanding the charging area while maintaining ease of operation through automated or manual repositioning.
2Adaptability or versatility
If traditional chargers are plugged into wall outlets, then the charging location is limited by the length of the charging cable, but the charging flexibility is reduced
Solution Approach 1:
The patent extracts the charging function from the wall outlet context by providing a self-contained wireless charging shelf with an integrated power source or battery. This removes the dependency on wall outlets and cable length constraints, allowing the charging device to be placed anywhere within the furniture space without being limited by cable reach.
Solution Approach 2:
The charging shelf is designed as a universal solution that can be installed in various furniture types (sofas, chairs, tables) and positions. The shelf can serve multiple functions including wireless charging, device storage, and adjustable positioning, making it adaptable to different charging scenarios without being constrained by fixed outlet locations or cable lengths.
3Adaptability or versatility
If a cassette shelf mechanism includes multiple moving parts (trolley, hinges, tensioning module), then the adaptability and positioning flexibility are improved, but the device complexity increases
Solution Approach 1:
The patent segments the charging system into modular components: a mounting plate, a movable trolley with rollers, a rotary hinge mechanism, a pivot hinge, and an extension tensioning module. Each component performs a specific function and can be independently adjusted or replaced. This segmentation provides positioning flexibility while managing complexity through functional decomposition, allowing users to benefit from adaptability without requiring understanding of the entire mechanism.

AI summary
A cassette shelf mechanism includes a mounting plate; a trolley equipped with rollers mounted on the mounting plate, allowing movement in an up-down direction; a rotary hinge attached to the trolley, including a lower part; a pivot hinge including an upper part connected to a shelf plate; and an extension tensioning module mounted on the mounting plate, which includes a cable connected to the trolley to facilitate the movement in the up-down direction, wherein the shelf plate is configured to unfold from a closed to an open position by rotating the upper part of the rotary hinge relative to the lower part.
