Leg Massage Alignment via Optical Feedback Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing massage apparatuses with independently operable leg massage units often fail to maintain effective alignment, leading to discomfort and inadequate massage experiences for users.
Innovation Solution
A massage apparatus equipped with alignment sensors and a control unit that synchronizes the movement of first and second leg massage units using light emitting and receiving sensors, adjusting speed and rotation to ensure proper alignment and synchronized operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If leg massage units are made independently operable to provide customized massage for each leg, then massage adaptability is improved, but alignment precision deteriorates causing discomfort
Solution Approach 1:
The patent employs optical sensors to detect the position and alignment status of the leg massage units in real-time, feeding this information back to the control unit. Based on this feedback, the control unit dynamically adjusts the rotation angles and speeds of the massage units to maintain proper alignment while preserving independent operation capabilities.
Solution Approach 2:
The system transitions from static alignment to dynamic alignment adjustment. The leg massage units can rotate independently at variable speeds, and the control unit continuously monitors and adjusts their positions during operation to maintain alignment, allowing the system to adapt to different user positions and massage requirements.
2Extent of automation
If light emitting and receiving sensors are added to control alignment, then alignment control capability is improved, but device complexity increases
Solution Approach 1:
Optical sensors serve as intermediaries between the leg massage units and the control unit. These sensors detect alignment status and transmit signals to the control unit, which then processes the information and issues commands to adjust the massage units. This intermediary approach simplifies the overall control architecture by using passive optical detection rather than complex active measurement systems.
