Internal Battery Mounting for Motorized Screen Drive Trunk
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing home automation systems with motorized drive mechanisms for screens face aesthetic and performance issues due to the external positioning of batteries, which leads to heat loss and moisture infiltration through fixing holes in the screen guide rail.
Innovation Solution
A fixing device is integrated within the home automation system's trunk, allowing the battery to be mounted internally on a mounting support, eliminating the need for external fixation and preventing heat and moisture issues, while also enabling solar energy recharging through a photovoltaic cell connected magnetically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the battery is positioned externally against the side guide rail, then the assembly is simplified, but the aesthetics are degraded and heat loss occurs
Solution Approach 1:
The battery is integrated inside the trunk housing, nesting the power supply within the existing structure. This eliminates external mounting requirements while maintaining accessibility through the same mounting bracket mechanism that secures the actuator.
Solution Approach 2:
The battery mounting function is merged with the existing trunk structure and mounting bracket system. The mounting bracket serves dual purposes: securing the actuator torque bracket and providing mounting surfaces for the battery, consolidating multiple functions into a single integrated component.
2Ease of operation
If fixing holes are made in the screen guide side rail to mount the battery externally, then the battery can be mounted, but heat loss and moisture infiltration occur
Solution Approach 1:
The battery is nested within the trunk housing interior, eliminating the need for penetration holes in the guide rail. The mounting bracket provides internal mounting surfaces that accommodate the battery without compromising the structural integrity or sealing of the guide rail.
Solution Approach 2:
The mounting bracket acts as an intermediary structure that provides mounting capability for the battery without requiring direct attachment to the guide rail. This mediator enables battery mounting while preserving the guide rail's sealing properties.
3Device complexity
If the battery is positioned outside the trunk, then the assembly is simpler, but the aesthetics are compromised
Solution Approach 1:
The battery is nested within the trunk housing, concealing it from external view while maintaining functional accessibility. This internal positioning preserves the clean external appearance of the home automation installation.
Solution Approach 2:
The battery integration is merged with the trunk's internal structure, utilizing the existing mounting bracket and housing space. This consolidation maintains aesthetic simplicity while providing necessary functionality.
