Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a long electrical cable is used to connect the actuating device to the electrical grid, then the actuating device can be powered, but the cable becomes hard to move and constantly in the way during normal use
Solution Approach 1:
The power supply system is segmented into a fixed power source integrated into the stuffed chair and a movable battery unit that can be independently removed and replaced. This segmentation allows the power supply function to be maintained while eliminating the cumbersome long cable, as the battery unit portably provides power without requiring a physical cable connection to the electrical grid.
Solution Approach 2:
The battery unit is extracted as a separate, removable component from the stuffed chair structure. This extraction allows the power supply function to be decoupled from the chair body, enabling easy removal and replacement of the battery unit without affecting the chair or requiring cable management, thus solving the problem of the cable being in the way during normal use.
2Reliability
If the battery is mounted inside the stuffed chair with a plug extending through the chair, then the battery can be recharged, but the access to the battery becomes relatively difficult and replacement requires skilled personnel
Solution Approach 1:
The battery system is segmented into a removable battery unit and a corresponding receptacle in the stuffed chair. This segmentation allows the battery unit to be independently accessed, removed, and replaced without requiring disassembly of the chair or complex electrical connections, making battery replacement a simple user-friendly operation that does not require skilled personnel.
Solution Approach 2:
The battery unit is extracted as a standalone component with external access through a opening in the stuffed chair. This extraction eliminates the need for complex internal mounting and electrical connections, allowing users to easily access, remove, and replace the battery unit by simply plugging it in or taking it out, without requiring technical expertise for restoration of electrical connections.
3Ease of operation
If the battery is made easily accessible for replacement, then user accessibility is improved, but the electrical connection between the battery, actuating device and recharging plug becomes more complex
Solution Approach 1:
The electrical connection interface is merged into a single integrated plug-and-socket system that combines power delivery and data communication functions. This merging allows the battery unit to be connected to the stuffed chair through a single simple plugging action, providing easy user access while avoiding complex separate electrical connections for power and recharging, as both functions are unified in the single connection interface.
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
Enables easy battery replacement and power management, reducing the need for skilled personnel and improving user accessibility while maintaining the actuating device's functionality.
Implementation Method 1
a tooth (27), which is obtained through one of the main lateral walls (16) of the box (11), is mobile, relative to the box (11), in a moving direction (25) between a locking position, in which the tooth (27) locks the battery (18) in its operating position, and a release position
Implementation Method 2
The battery (18) is moved to its extracted position (figures 3 and 4) by a spring (31), which is hooked to the wall (15) and is interposed between the walls (15) and (22)

AI summary
A stuffed chair with one or more seats, in particular an armchair or a couch, has a seat (2), a backrest (3), and at least one mobile part (5), which is configured to move relative to a fixed part (6) due to the action of an actuating device (7) supplied with power by a rechargeable battery (18) housed inside a containing box (11); the containing box (11) being mounted in the stuffed chair and opening up outwards in correspondence to an outer surface (8) of the stuffed chair to allow access to the rechargeable battery (18).
