Solution Overview
Problem
Existing seat devices with control mechanisms mounted on plate-shaped members often expose the mounting parts, making them difficult to assemble and potentially compromising the quality of the device.
Innovation Solution
A seat device design that incorporates a plate-shaped member fixed to the seat part, with a holder for the control mechanism mounted on this member in a way that covers the mounting part, using first and second mounting parts and engaging parts to stabilize the plate-shaped member and improve rigidity, while allowing easier assembly by mounting along the width or front-to-back direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the holder holding the control mechanism is mounted on the seat part using a plate-shaped member, then the control mechanism can be securely mounted, but the mounting part of the plate-shaped member is exposed which compromises the quality of the seat device
Solution Approach 1:
The mounting part of the plate-shaped member is nested within the holder structure. Specifically, the holder includes a mounting part receiving portion that receives and conceals the mounting part of the plate-shaped member, creating a nested configuration where the less aesthetically pleasing mounting components are hidden inside the holder's structure.
Solution Approach 2:
The mounting part of the plate-shaped member is extracted from the visible exterior and relocated to the interior of the holder. By separating the mounting function from the visible surface, the design extracts the functional element and places it in a concealed location within the holder structure.
2Ease of manufacture
If the holder is mounted on the plate-shaped member with simple mounting parts, then the assembly process is simplified, but the plate-shaped member lacks stability and rigidity
Solution Approach 1:
The mounting system is segmented into multiple functional parts: the plate-shaped member with engaging parts for attachment to the seat part, and the holder with a receiving portion that provides additional support. This segmentation allows each component to contribute to both simplicity and strength.
Solution Approach 2:
The mounting structure uses a composite configuration combining the plate-shaped member (providing base support) with the holder structure (providing additional rigidity). The combination of these two components creates a composite mounting system that achieves both ease of assembly and structural strength.
3Adaptability or versatility
If multiple separate components are used for the holder, control mechanism, and mounting structure, then each component can be optimized independently, but the number of components increases and assembly becomes more complex
Solution Approach 1:
The holder structure merges multiple functions into a single integrated component: it provides mounting support for the control mechanism, conceals the mounting parts of the plate-shaped member, and offers structural rigidity. This merging reduces the total number of components while maintaining the ability to optimize each functional aspect.

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 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.
