Innovation Solution
The LED light strip incorporates a flexible protective sleeve with an accommodating cavity, a soft light panel, and a reinforcing panel bonded with fixing glue, featuring insulating soft films, circuit layers, chip electrodes, a protective circuit, and optical layers to enhance flexibility, durability, and light emission efficiency, while preventing air bubbles through a stripe groove design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the soft light panel is made wide enough to omit copper strand conductors, then the manufacturing complexity is reduced, but the panel becomes less bendable
Solution Approach 1:
The patent divides the conductor system into multiple thin circuit layers (first circuit layer, second circuit layer, third circuit layer) instead of using a single thick copper strand. This segmentation allows the conductors to be integrated into the soft light panel structure, maintaining flexibility while reducing manufacturing complexity.
Solution Approach 2:
The circuit layers are nested within the soft light panel structure, with the first, second, and third circuit layers positioned between different functional layers of the panel. This nesting integrates the conductor system into the panel itself, eliminating the need for separate copper strands and maintaining bendability.
2Stability of the object's composition
If the accommodating cavity is made same or slightly smaller in size with the soft light panel to prevent sliding, then the panel is secured, but air bubbles form between the panel and cavity bottom
Solution Approach 1:
The patent extracts air from the accommodating cavity by providing a communication channel between the cavity interior and exterior. This allows air bubbles to be discharged from the cavity, eliminating the harmful effect while maintaining the tight fit that prevents panel sliding.
Solution Approach 2:
The patent applies a light-reflecting layer to the bottom surface of the accommodating cavity. This layer reflects light to mask the appearance of any remaining air bubbles or gaps, making them invisible to users and thus eliminating the aesthetic harm without changing the physical fit.
3Illumination intensity
If multiple LED light sources are arranged in series on the soft light panel, then the light emission effect is enhanced, but the entire string fails when one LED is damaged
Solution Approach 1:
The patent segments the series circuit into multiple parallel branches, each containing one or more LED light sources. This segmentation allows current to flow through alternative paths when one LED fails, maintaining light emission while preserving the enhanced illumination effect of multiple LEDs.
Solution Approach 2:
The patent creates a dynamic circuit configuration where the parallel branches can adaptively redistribute current based on the operational status of individual LEDs. When one LED fails, the circuit dynamically reconfigures to maintain illumination, combining the benefits of series arrangement (higher voltage operation) with parallel redundancy (fault tolerance).
4Illumination intensity
If the flexible protective sleeve is made transparent to facilitate light passage, then light transmission is improved, but air bubbles and internal components become visible, impairing ornamental effect
Solution Approach 1:
The patent applies a light-reflecting layer to the bottom surface of the accommodating cavity, which reflects light to mask the appearance of air bubbles and internal components. This maintains the transparent or translucent property of the protective sleeve for light transmission while eliminating the aesthetic harm of visible imperfections.
Solution Approach 2:
The light-reflecting layer acts as an intermediary between the internal components (air bubbles, circuit layers) and the external environment. It intercepts light that would otherwise reveal the internal structure, reflecting it back to create a uniform appearance while allowing light from the LEDs to pass through the protective sleeve.
