Powered Recliner Chair Control for Remote Venue Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional powered recliner chairs require multiple motors for multi-positional functions, leading to large and expensive units, and are typically controlled only locally, lacking remote operation capabilities and efficient power management.
Innovation Solution
A venue seating management system with a chair controller that integrates various inputs (local user control, remote control, sensors, and power management) and outputs (actuators, lighting, heating) to enable remote operation, power demand management, and efficient maintenance, using a smart power supply to coordinate multiple chairs and manage power distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple motors are used for multi-positional functions, then the chair can provide lift, tilt, leg rest extension, and reclining functions, but the chair becomes extremely large and expensive
Solution Approach 1:
A single motor is designed to perform multiple functions (lift, tilt, leg rest extension, and reclining) through a unified drive mechanism with selective engagement, eliminating the need for separate motors for each function and reducing overall system complexity and cost
2Adaptability or versatility
If power drive function is provided for extending leg rest, lifting chair, and reclining chair, then the chair can achieve multi-positional adjustment, but the chair requires power return function which increases complexity
Solution Approach 1:
The motor automatically reverses rotation direction based on the position of the chair components, providing power return function without requiring separate control systems. The motor serves itself by using the mechanical position feedback to determine when to reverse, eliminating the need for complex external control mechanisms
3Strength
If the chair is designed to support heavy loads above 300 pounds, then the chair can accommodate heavier users, but multiple motors are required
Solution Approach 1:
The drive mechanism is segmented into multiple independently controllable phases or stages, allowing a single motor to handle heavy loads by sequentially engaging different mechanical pathways. This segmentation enables one motor to distribute the load across multiple mechanical advantage points, achieving heavy load support without requiring multiple motors
4Ease of operation
If only local control is provided, then the chair can be controlled by the occupant, but remote operation capabilities are lacking
Solution Approach 1:
A control system with multiple input interfaces is introduced as an intermediary between the user and the motor. This system accepts both local inputs (buttons on the chair) and remote inputs (wireless controllers), translating all inputs into motor control signals, thereby enabling both local and remote operation through a unified control architecture
