Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power supply assemblies for motorized actuators, such as those for doors, windows, and blinds, lack a simple and ergonomic solution for adjusting and protecting against unintended movements during transport and reducing energy consumption after installation, particularly for self-powered systems.
Innovation Solution
A modular power supply assembly with a man-machine interface that allows integrators and users to easily enable or disable radio listening functions, reset receivers, and manage battery charging through a functional button, enabling efficient energy management and reduced battery discharge without disassembling the system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the radio listening function is left enabled during transport and installation, then the actuator can be easily adjusted and paired, but unnecessary battery discharge occurs reducing energy efficiency
Solution Approach 1:
The actuator is equipped with a functional button that allows the user to activate the radio listening function only when needed for adjustment and pairing. This preliminary setup of the button interface enables the user to control the radio function's activation state, preventing unnecessary battery discharge during transport while maintaining ease of operation during installation through simple button presses
2Reliability
If the actuator is supplied directly by mains power, then continuous operation is ensured, but the system lacks autonomy and requires external power connection
Solution Approach 1:
The actuator is designed with multi-functionality to operate in two power supply modes: autonomous operation using an integrated battery kit and continuous operation using mains power. The system includes a battery kit for autonomous operation and an auxiliary socket for mains connection, allowing the same actuator to adapt to different installation scenarios and power availability conditions
3Ease of operation
If the auxiliary socket is placed in accessible locations for user connection, then ease of use is improved, but the system becomes more complex and requires additional components
Solution Approach 1:
The auxiliary socket and its connection components are extracted as a separate functional element that can be integrated into the actuator housing. This allows the socket to be placed in accessible locations for user connection while keeping the overall system design modular and manageable, reducing the perceived complexity by separating the power connection function from the main actuator mechanisms
