Bed Apparatus with Dual-Speed Control for Quiet Automatic Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bed apparatuses lack the ability to adjust section positions smoothly and quietly, potentially disturbing the user's sleep and posing safety risks during automatic operations.
Innovation Solution
A bed apparatus with a supporting unit and control unit that allows manual operation speeds higher than automatic operation speeds, minimizing noise and ensuring safe, gradual adjustments based on user states detected by a body motion detector.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the bed apparatus operates at high speed to improve responsiveness to user input, then the operation speed is improved, but noise and safety risks increase during automatic operations
Solution Approach 1:
The patent applies dynamics by making the operation speed variable rather than fixed. The control unit dynamically adjusts the speed based on the operation mode: using higher speeds for manual user operations to ensure responsiveness, and lower speeds for automatic operations to minimize noise and safety risks. This dynamic speed adjustment resolves the contradiction between needing high speed for responsiveness and low speed for safety and quiet operation.
2Ease of operation
If the bed apparatus uses automatic control to reduce manual operation burden, then ease of operation is improved, but the ability to perform rapid adjustments when needed is reduced
Solution Approach 1:
The system dynamically switches between automatic and manual control modes with different speed characteristics. Automatic mode provides ease of operation with gradual adjustments, while manual mode enables rapid adjustments when needed. The control unit allows users to override automatic control and directly manipulate the bed apparatus at higher speeds, thus resolving the contradiction between ease of automatic operation and the need for rapid adjustments.
Solution Approach 2:
The bed apparatus provides self-service through automatic control for routine operations, reducing manual burden. However, it also empowers users to take control when needed through manual operation interfaces, allowing them to perform rapid adjustments themselves. This self-service capability with user override resolves the contradiction between automatic ease of operation and rapid adjustability.

AI summary
A high-performance bed apparatus is provided. The bed apparatus includes a supporting unit that supports a user, and a control unit that controls an operation of the supporting unit, wherein a speed of the operation of the supporting unit in a case where the user manipulates the supporting unit is higher than a speed at which the control unit automatically causes the supporting unit to operate.
