Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stuffed chairs with actuating devices face issues due to long and cumbersome electrical cables and difficult battery access, requiring skilled personnel for replacement and reconnection.
Innovation Solution
A power supply system within the chair featuring a cup-shaped box with a rechargeable battery and sliding mechanism, allowing easy battery replacement and charging indicator lights, eliminating the need for external cables and skilled personnel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If an electrical cable is used to supply power to the actuating device, then the actuating device can be powered continuously, but the cable becomes long and hard to move, constantly getting in the way during normal use
Solution Approach 1:
The patent extracts the power source (battery) from the external environment and places it inside the stuffed chair. This eliminates the need for an external electrical cable, allowing the actuating device to be powered without the cable getting in the way during use.
Solution Approach 2:
The battery is nested within the stuffed chair structure, specifically housed in a compartment within the fixed part. This nested arrangement allows the power source to be integrated into the furniture without adding external bulk or requiring external connections.
2Ease of operation
If a rechargeable battery is mounted inside the stuffed chair with a plug extending through, then external cable is eliminated, but access to the battery becomes difficult and replacement requires skilled personnel
Solution Approach 1:
The patent segments the battery system into a removable battery unit and a receiving compartment. The battery can be independently removed from the stuffed chair without requiring disassembly of the entire structure or specialized tools, enabling easy replacement by users.
Solution Approach 2:
The battery compartment is designed with dynamic access - the panel can be opened and the battery removed/inserted easily. This dynamic design contrasts with fixed, sealed battery compartments that would require complex disassembly for replacement.
3Reliability
If the battery compartment is enclosed for safety and protection, then the battery is protected from damage, but access to the battery becomes difficult
Solution Approach 1:
The battery compartment is segmented with a removable panel that provides protection when closed but easy access when opened. This segmented design allows the battery to be both protected during operation and easily accessible when needed for replacement or charging.
Solution Approach 2:
The design enables self-service battery replacement and charging by the end user. The simple panel access mechanism allows users to independently service the battery without requiring skilled personnel, balancing protection with accessibility.

AI summary
A stuffed chair with one or more seats, in particular an armchair or a couch, has a seat, a backrest, and at least one mobile part, which is configured to move relative to a fixed part due to the action of an actuating device supplied with power by a rechargeable battery housed inside a containing box; the containing box being mounted in the stuffed chair and opening up outwards in correspondence to an outer surface of the stuffed chair to allow access to the rechargeable battery.
