Electric Furniture Drive Interface for Static Actuator Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture drive systems require assembly movement for identification, which can lead to improper component matching and potential damage or accidents, especially when used with varying furniture sizes and weights.
Innovation Solution
An identification device is integrated at the interface of the electric furniture drive, allowing configuration recognition upon connection without moving the components, using sensors to detect mechanical actuator parameters and adjust operating parameters accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If assembly movement is required for identification, then the identification device can detect configuration, but damage or accidents may occur during testing
Solution Approach 1:
The patent applies preliminary action by performing configuration identification before any movement or operation of the actuator. Sensors detect mechanical parameters (position, force, configuration) during the assembly connection phase, allowing the control device to pre-configure operating parameters before the actuator is activated, thus avoiding damage during testing
Solution Approach 2:
The patent replaces mechanical movement-based identification with sensor-based detection. Instead of requiring the actuator to move through its range of motion to identify configuration, sensors (such as position sensors, force sensors, or encoders) detect mechanical parameters electrically/magnetically during static connection, eliminating the need for dangerous movement during identification
2Adaptability or versatility
If the same drive system is used for varying furniture sizes and weights, then versatility is improved, but parameter matching becomes difficult
Solution Approach 1:
The patent applies self-service by enabling the drive system to automatically identify and adapt to different furniture configurations. Sensors detect mechanical parameters during assembly, the control device processes this information to determine furniture type, size, and weight characteristics, and automatically configures operating parameters without requiring manual adjustment or complex setup procedures
Solution Approach 2:
The patent utilizes parameter changes by dynamically adjusting operating parameters (force, speed, position limits, acceleration) based on detected furniture characteristics. The control device modifies these parameters in real-time based on sensor feedback, allowing the same hardware to safely and effectively operate with varying furniture sizes and weights
3Reliability
If identification occurs after assembly, then component matching can be verified, but time is lost during movement testing
Solution Approach 1:
The patent performs identification as a preliminary action during the assembly connection phase, before any movement testing or operation. Sensors detect configuration parameters during the connection process itself, allowing component compatibility to be verified immediately without requiring separate testing time
Solution Approach 2:
The patent merges the identification process with the assembly process. The same sensors and connection mechanisms used for physical assembly also perform configuration detection, combining two functions (mechanical connection and identification) into a single integrated process, thereby eliminating separate identification time
