Solution Overview

Problem

Existing methods for manufacturing accessories like rings, bracelets, and earrings using small gemstones are inefficient due to the small size of the gemstones, leading to increased manufacturing costs and potential deformation from heat during the fixing process.

Innovation Solution

A method involving a ring-shaped accessory body with an insertion groove and fixing holes, where a wire is passed through small gemstones with through holes and laser-welded to the fixing holes, allowing for the secure attachment of the gemstones and minimizing heat-induced deformation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If small gemstones are used to decorate accessories, then aesthetic value and design flexibility are improved, but manufacturing complexity and cost increase due to difficulty in handling and fixing the small gemstones

Engineering Contradiction:

Improvedesign flexibilityVSAvoidmanufacturing complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The accessory body is segmented into distinct functional zones: a receiving groove for positioning gemstones and separate fixing holes for securing them. This segmentation allows small gemstones to be handled and fixed independently, reducing manufacturing complexity while maintaining design flexibility

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A wire is introduced as an intermediary element that passes through the small gemstones and is then fixed to the accessory body. This intermediary component simplifies the handling and positioning of small gemstones during manufacturing, reducing overall manufacturing complexity

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If conventional fixing methods are used for small gemstones, then gemstone attachment is achieved, but manufacturing cost increases due to need for additional fixing supports and complex structures

Engineering Contradiction:

Improvegemstone attachmentVSAvoidmanufacturing cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The fixing hole is merged with the receiving groove structure, eliminating the need for separate fixing supports. The groove and fixing mechanism are integrated into a single accessory body structure, reducing manufacturing cost while ensuring reliable gemstone attachment

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The fixing function is extracted from complex supporting structures and simplified to a direct wire-to-accessory body connection through laser welding. This extraction removes unnecessary components and reduces manufacturing cost while maintaining attachment reliability

Inventive Principle:

Principle #2Taking out (Extraction)

3Productivity

If laser welding is used to fix wire to accessory body, then manufacturing efficiency and precision are improved, but heat-induced deformation may occur

Engineering Contradiction:

Improvemanufacturing efficiencyVSAvoidheat-induced deformation

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The receiving groove is designed with specific local geometric properties that concentrate and control the laser beam energy. This local quality enhancement allows precise laser welding at the fixing hole location while minimizing heat diffusion to surrounding areas, preventing deformation

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

Traditional mechanical fixing methods are replaced with laser welding technology. The laser provides non-contact, precise energy delivery that achieves secure fixation without mechanical pressure, improving manufacturing efficiency while the controlled energy delivery prevents excessive heat-induced deformation

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
