Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing noise reduction systems for windows, such as those described in the Carme patent, face issues with non-homogeneous membrane tension due to irregular bonding between the membrane and side walls, leading to asymmetrical deformation and reduced efficiency over time, especially under UV and thermal variations.
Innovation Solution
A multi-glazed window design featuring a vibrating membrane with hooking members at its edges that secure to complementary hooking members on the side walls, ensuring a mechanical connection that maintains homogeneous tension and is durable against environmental changes, along with a rigid piston and electromagnetic coil system for vibratory movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the membrane is bonded to the side walls using gluing, then the membrane is suspended and generates elastic restoring force, but the bonding creates irregularities at the junction resulting in uneven tension and asymmetrical deformation
Solution Approach 1:
The patent introduces an intermediary component (adjustable mounting mechanism with hooks or clips) between the membrane and side walls to replace direct gluing. This intermediary allows for uniform tension distribution and adjustable positioning, eliminating the irregularities caused by bonding while maintaining secure suspension.
Solution Approach 2:
The patent implements an adjustable mounting mechanism that allows dynamic adjustment of membrane tension and position. This enables precise control over membrane uniformity during installation and maintenance, addressing the manufacturing precision issue while preserving reliability.
2Reliability
If the membrane is bonded using elastic seals, then the membrane is suspended with balanced tension, but the bond quality deteriorates over time due to UV radiation and temperature variations
Solution Approach 1:
The patent replaces the elastic seal intermediary with a more durable mounting mechanism (such as UV-resistant hooks, clips, or mechanical fasteners) that connects the membrane to the side walls. This new intermediary maintains tension balance while being resistant to environmental degradation from UV radiation and temperature variations.
Solution Approach 2:
The patent employs a durable, replaceable mounting mechanism that can be easily replaced if needed, rather than relying on long-lasting but environmentally vulnerable adhesive bonds. This approach prioritizes long-term reliability through replaceability over permanent bonding.
3Ease of manufacture
If the membrane edges are folded back and fixed externally, then the membrane is suspended, but the installation process creates irregularities leading to uneven tension
Solution Approach 1:
The patent introduces a specialized mounting intermediary (such as a tensioning bar, adjustment mechanism, or standardized clamping system) that facilitates easy installation while ensuring uniform tension distribution. This intermediary provides a controlled interface between the membrane and mounting structure, eliminating irregularities.
Solution Approach 2:
The patent implements preliminary tensioning and positioning features in the mounting mechanism that ensure uniform membrane tension from the outset during installation. This preliminary action prevents uneven tension development and simplifies the installation process by providing built-in alignment and tensioning guidance.
