Solution Overview

Problem

Existing SSD case designs often fail to robustly fasten the LED module and do not provide uniform brightness due to the shape of the LED.

Innovation Solution

A portable SSD module design that includes a case with a window, an SSD, an LED module, and a main bracket. The main bracket supports the LED module, ensuring it is firmly combined with the case, and the LED module features a triangular diffusing groove to achieve uniform light diffusion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional LED module is used in the SSD case, then the LED can indicate operation status, but the LED module cannot be robustly fastened to the case

Engineering Contradiction:

Improvefastening reliabilityVSAvoidmounting structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The LED module is integrated with the fingerprint sensor to form a unified component assembly. This merging eliminates the need for separate mounting structures for the LED module, as the combined unit is supported by the fingerprint sensor mounting bracket, thereby improving fastening reliability while reducing overall device complexity

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The fingerprint sensor mounting bracket serves multiple functions: it supports the fingerprint sensor, supports the integrated LED module, and provides structural anchoring points. This multi-functional design resolves the fastening reliability issue without adding dedicated LED mounting hardware, thus avoiding increased complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Illumination intensity

If a conventional LED module is used in the SSD case, then the LED can indicate operation status, but the light from the LED is not uniformly diffused

Engineering Contradiction:

Improvelight uniformityVSAvoidoptical structure complexity

Core Design Contradiction:

Illumination intensityVSDevice complexity

Solution Approach 1:

A diffusing groove with a triangular cross-section is created locally at the light-emitting surface of the LED module. This localized optical feature modifies light diffusion characteristics without requiring complex optical components throughout the entire device, achieving uniform light distribution while maintaining simplicity

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The diffusing groove employs a curved triangular cross-section rather than sharp angular edges. This curvature design facilitates smooth light diffusion patterns, preventing concentrated light spots and achieving uniform illumination across the indicator surface without complex optical systems

Inventive Principle:

Principle #14Spheroidality (Curvature)

3Ease of operation

If the LED module is exposed through the window for indication, then operation status can be displayed, but the LED module is vulnerable to external elements

Engineering Contradiction:

ImprovevisibilityVSAvoidshock and external elements

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The LED module is nested within the case structure, with only the light-emitting portion exposed through the window. The fingerprint sensor mounting bracket provides an internal support framework that protects the LED module while allowing light transmission, effectively shielding vulnerable components from external elements while maintaining visibility

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The window acts as an intermediary element that transmits light from the protected LED module to the external environment. The fingerprint sensor mounting bracket serves as a structural intermediary, providing mechanical support and protection while allowing optical transmission, thus resolving the conflict between protection and visibility

Inventive Principle:

Principle #24Intermediary (Mediator)
