Solution Overview
Problem
Existing seat devices with control mechanisms mounted using plate-shaped members often expose the mounting parts, making it difficult to securely and efficiently attach the holder, which can lead to installation issues and reduced stability.
Innovation Solution
A seat device design featuring a plate-shaped member with specific mounting and engaging parts that cover the mounting area, allowing for easier and more secure attachment of the holder, while also providing protection for the holder's front end and reducing component count by integrating the control mechanism, moving device, and battery within a single holder.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a plate-shaped member with mounting parts is used to attach the holder to the seat part, then the holder can be securely mounted, but the mounting parts become exposed which affects appearance and may cause installation issues
Solution Approach 1:
The mounting part is nested within the holder structure. Specifically, the mounting part protrudes in a first direction from the plate-shaped member, and the holder is mounted on this protruding mounting part such that the mounting part becomes embedded or nested within the holder's mounting surface, thereby eliminating exposure while maintaining secure attachment
Solution Approach 2:
The solution addresses the exposure problem by utilizing a third dimension (depth/protrusion direction). The mounting part protrudes from the plate-shaped member in a first direction, and the holder is positioned such that it covers this protrusion from another dimension, transforming the exposed mounting part into a nested configuration through spatial arrangement
2Reliability
If the holder is mounted on the plate-shaped member using conventional methods, then the control mechanism can be attached, but the mounting process becomes complex and time-consuming
Solution Approach 1:
The plate-shaped member is pre-configured with a protruding mounting part that extends in a first direction. This preliminary structural preparation eliminates the need for complex assembly operations during installation, as the holder can be directly mounted onto the pre-positioned mounting part, significantly reducing mounting time while ensuring reliable attachment
3Adaptability or versatility
If multiple separate components are used for the control mechanism, moving device, and battery, then each component can be independently optimized, but the overall device complexity and component count increase
Solution Approach 1:
The holder is designed to integrate and hold multiple components (control mechanism, moving device, and battery) within a single unified structure. This merging approach reduces the overall component count and simplifies the device architecture while maintaining the functional independence of each integrated component through separate mounting spaces or compartments within the holder

AI summary
In a configuration in which a holder holding a controller is mounted on a seat part with a plate-shaped member, the exposure of the mounting part of the plate-shaped member on which the holder is mounted is eliminated. A seat device includes a pressure sensor measuring a value relating to the seated person's state a vibration imparting device performing a vibration imparting operation, an ECU controlling the vibration imparting device corresponding to the measurement result of the pressure sensor, a holder holding the ECU, and a mounting bracket fixed to a lower frame such that the holder is mounted on the lower frame of a seat part. The mounting bracket includes a mounting projection on which a side wall of the holder is mounted in a predetermined mounting direction. When the side wall is mounted on the mounting projection, the mounting projection is covered with the side wall.
