Solution Overview

Problem

Existing computing components face challenges in integrating additively manufactured protrusions with cosmetic surfaces without compromising the surface's uniformity and structural integrity, as traditional manufacturing methods often result in heat-affected zones that alter the cosmetic surface's appearance and microstructure.

Innovation Solution

The use of additively manufactured protrusions extending from a prefabricated sheet with a cosmetic surface, where the protrusions are formed using techniques like Selective Laser Melting, minimizing the heat-affected zone and maintaining the surface's uniformity by applying layers that bond microstructurally with the sheet, ensuring a uniform cosmetic appearance and structural support.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional manufacturing methods are used to create protrusions on cosmetic surfaces, then structural support is achieved, but the cosmetic surface's uniformity and appearance are compromised due to heat-affected zones

Engineering Contradiction:

Improvestructural supportVSAvoidcosmetic surface uniformity

Core Design Contradiction:

StrengthVSManufacturing precision

Solution Approach 1:

The patent applies local quality by using selective laser melting to create protrusions only in specific locations where structural support is needed, while leaving the cosmetic surface areas unaffected. The laser parameters are controlled to limit heat-affected zones to minimal dimensions, ensuring that the cosmetic surface maintains its uniformity and appearance while the protrusions provide the necessary structural support in localized regions.

Inventive Principle:

Principle #3Local quality

2Strength

If additively manufactured protrusions are used, then structural support and shielding are provided, but the heat-affected zone size must be minimized to preserve surface uniformity

Engineering Contradiction:

Improvestructural supportVSAvoidheat-affected zone

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent converts the harmful thermal effects of additive manufacturing into a beneficial process by using selective laser melting with precisely controlled parameters. The laser energy is applied in a manner that melts and fuses material to create strong protrusions while the heat-affected zone is deliberately kept minimal through controlled pulse duration and power settings. This approach transforms the potentially harmful thermal influence into a controlled manufacturing advantage that achieves both structural integrity and surface preservation.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

3Adaptability or versatility

If protrusions are added to the cosmetic surface, then functional requirements are met, but the cosmetic appearance uniformity may be compromised

Engineering Contradiction:

Improvefunctional integrationVSAvoidcosmetic surface uniformity

Core Design Contradiction:

Adaptability or versatilityVSShape

Solution Approach 1:

The patent segments the component into distinct functional zones: the cosmetic surface area where appearance uniformity is critical, and the protrusion areas where structural support and shielding functions are required. By spatially separating these functions and using selective additive manufacturing only in non-cosmetic or minimally visible areas, the design achieves both functional requirements and aesthetic uniformity without compromise.
