Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional motion chairs use multiple motors and metal mechanisms to achieve three-degree-of-freedom movements, then the motion functionality is improved, but the structural complexity and manufacturing cost increase
Solution Approach 1:
The patent combines multiple motor functions into a single motor by integrating the cushion material with the chair frame to form an integrated flexible structure. This single motor drives the entire three-degree-of-freedom motion system through the flexible chair body, eliminating the need for multiple separate motors and complex metal mechanisms while maintaining full motion functionality.
Solution Approach 2:
The patent uses a flexible chair body made of cushion material that can bend and deform to enable three-degree-of-freedom movements. This flexible structure replaces rigid metal mechanisms, allowing the chair to achieve complex motions through material flexibility rather than mechanical linkages, thereby simplifying the overall structure.
2Manufacturing precision
If conventional motion chairs use metal mechanisms and multiple actuators, then the motion precision is improved, but the weight and bulkiness increase
Solution Approach 1:
The patent employs a flexible chair body constructed from cushion material that can deform to achieve precise three-degree-of-freedom movements. This flexible membrane structure replaces heavy metal components, maintaining motion precision through controlled deformation while dramatically reducing the overall weight and bulk of the chair.
Solution Approach 2:
The patent substitutes traditional mechanical systems (motors, metal linkages, gears) with a flexible material-based system. A single motor generates force that is distributed throughout the flexible chair body, which then achieves precise motions through its inherent flexibility and elasticity, eliminating the need for heavy mechanical transmission components.
3Stability of the object's composition
If conventional motion chairs use separate installation of chair body and cushion material on metal frame, then the structural stability is improved, but the manufacturing cost and complexity increase
Solution Approach 1:
The patent merges the chair body and cushion material into a single integrated flexible structure that is directly formed from the cushion material itself. This eliminates the separate installation process and metal frame assembly, reducing manufacturing complexity while maintaining structural stability through the unified flexible design.
4Adaptability or versatility
If conventional motion chairs use multiple motors for all movements, then the motion capability is improved, but the energy consumption increases
Solution Approach 1:
The patent consolidates multiple motor functions into a single motor that drives the entire motion system through the flexible chair body. This single motor can generate all necessary movements (upward, downward, forward, backward, leftward, rightward, and return motions) by selectively deforming different regions of the flexible structure, thereby reducing energy consumption compared to running multiple motors simultaneously.

AI summary
An embodiment relates to an immersive couch, and more particularly to an immersive couch configured to be movable in three degrees of freedom using a concise and simple mechanism for moving an inflatable body, thereby not only improving convenience in use, safety, handling, storability, and maintainability, but also reducing manufacturing costs, operating costs, and maintenance costs. The immersive couch includes: a couch body formed as an inflatable body; a holding unit installed on the couch body; an actuation connecting member including one end connected to the holding unit; a rotary body connected to wind and unwind the actuation connecting member; a rotary body actuator rotating the rotary body forwards and backwards; and a controller controlling operations of the rotary body actuator.
