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

VSEngineering 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

Engineering Contradiction:
Improveassembly simplicityVSAvoidheat loss and moisture infiltration
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

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.

Inventive Principle:
Principle #7Nested doll (Nesting)

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.

Inventive Principle:
Principle #5Merging (Combining)

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

Engineering Contradiction:
Improvebattery mounting capabilityVSAvoidperformance degradation due to heat and moisture
Core Design Contradiction:
Ease of operationVSReliability

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.

Inventive Principle:
Principle #7Nested doll (Nesting)

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.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If the battery is positioned outside the trunk, then the assembly is simpler, but the aesthetics are compromised

Engineering Contradiction:
Improveassembly complexityVSAvoidaesthetic appearance
Core Design Contradiction:
Device complexityVSShape

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.

Inventive Principle:
Principle #7Nested doll (Nesting)

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.

Inventive Principle:
Principle #5Merging (Combining)
