Adjustable Support Device with Independent Head/Neck Pivot Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support devices for seating and lying furniture, such as box-spring beds, lack independent adjustability of the head/neck support part relative to the upper body support part, limiting user customization and comfort.
Innovation Solution
Incorporating a guiding mechanism at the upper body support part that serves as a mechanical carrier for an electromotive drive unit, allowing independent adjustment of the head/neck support part via a pivot lever and guiding rail, enabling separate adjustment from the upper body support part.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the head/neck support part is adjusted together with the upper body support part via a shared pivot lever mechanism, then the device complexity is reduced, but the adaptability and independent adjustability of the head/neck support part deteriorates
Solution Approach 1:
The support device is divided into multiple independently adjustable segments: the upper body support part (second support part) and the head/neck support part (third support part) can be adjusted separately through distinct pivot lever mechanisms. This segmentation allows each part to be customized independently while maintaining overall structural coherence.
Solution Approach 2:
A guiding mechanism acts as an intermediary element that connects the pivot lever for the upper body support part to the head/neck support part. The guiding provides a structured path that enables independent adjustment of the head/neck support part while maintaining proper mechanical coupling and alignment with the upper body support part.
2Adaptability or versatility
If a guiding mechanism with electromotive drive unit is added to enable independent adjustment of the head/neck support part, then the adaptability improves, but the device complexity increases
Solution Approach 1:
The guiding mechanism serves multiple functions simultaneously: it guides the pivot lever movement, provides structural support for the head/neck support part, and acts as a mounting carrier for the electromotive drive unit. This multi-functionality reduces the need for separate components and minimizes overall device complexity.
Solution Approach 2:
The electromotive drive unit is integrated directly into the guiding structure, allowing the guiding to serve its own adjustment needs while also supporting the head/neck support part. The system adjusts itself through the electromotive drive unit that is part of the guiding assembly, reducing the need for external control mechanisms.

AI summary
An electromotively adjustable support device 2 for a cushioning of a seating and/or lying furniture, in particular a mattress of a box-spring bed, comprises a first support part 12, to which a second support part 14 is pivotally connected, to whose end facing away from the first support part 12 a third support part 16 is pivotally connected. A pivot lever 28 pivotally disposed around a pivot lever pivot axis 30 serves to pivotally adjust the second support part 14 relative to the first support part 12. According to the invention, the second support part 14 comprises a guiding 32 for the end of the pivot lever 28 facing away from the pivot-lever-pivot-axis 30, wherein the guiding 32 carries an adjusting means for pivotally adjusting the third support part 16 relative to the second support part 14.
