Adjustable Bed Foundation Service Position for Component Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bed foundations lack easy access for servicing components, particularly electrical components, as they typically only adjust between limited positions that do not allow for sufficient access to internal parts.
Innovation Solution
An adjustable bed foundation with an electric actuator that raises a deck panel between lower and raised positions, and a manual service position further than the upper position, allowing users to manually move the deck panel for complete access to internal components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the actuator raises the deck panel to the upper position for normal operation, then the bed can be adjusted for user comfort, but the components remain inaccessible for servicing
Solution Approach 1:
The deck panel is designed to be dynamically positionable at multiple distinct positions (lower, upper, and service positions) rather than being limited to fixed positions. This allows the system to adapt between normal operation mode where the panel is at the upper position for bed adjustment, and maintenance mode where the panel can be manually moved to service positions to expose components for servicing.
Solution Approach 2:
The adjustment mechanism is segmented into distinct functional zones: the actuator-controlled range providing automated adjustment between lower and upper positions for normal operation, and the manual service positions beyond the actuator's travel limit that provide component accessibility. This segmentation allows each zone to serve its specific function optimally.
2Device complexity
If the actuator travel range is limited to the upper position, then the device complexity is reduced, but the serviceability of components is compromised
Solution Approach 1:
The system enables self-service maintenance by allowing users to manually move the deck panel beyond the actuator's automated travel range to service positions. This design empowers users to perform basic maintenance tasks themselves without requiring tool removal or complex disassembly procedures, as the panel can be easily positioned manually to expose components.
Solution Approach 2:
The manual service position extends beyond the actuator's designed travel range (excessive action) to provide the additional functionality of component accessibility. While the actuator only needs to provide controlled movement to the upper position for normal operation, the deck panel's mechanical design allows it to be manually moved further to service positions, adding serviceability without requiring the actuator to be more complex.

AI summary
A foundation for a bed system can include an actuator, a deck mechanism operably related to the actuator so as to be actuated between raised and lowered positions in response to actuation by the actuator, and a controller operably connected to the actuator and configured to drive the actuator to actuate the deck mechanism between a lower position and an upper position. The deck mechanism can be configured to move to a service position that is further than the upper position. The deck mechanism can expose and permit access to a serviceable component when the deck mechanism is in the service position. A method of using a foundation having a service position is also described.
