Solution Overview

Problem

Current methods for inserting objects into transparent casings result in visible seams and alignment issues, which are problematic for luxury articles like precious stones where visual appearance and precise positioning are crucial.

Innovation Solution

A method involving a multi-part transparent casing where an object is aligned between joint surfaces of two casing parts, fused together under pressure and temperature without visible seams, using a guide funnel and plunger element to ensure precise positioning and prevent displacement, and optionally creating a vacuum to eliminate air inclusions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the casing parts are fused-on with an object placed therein, then the object can be incorporated in the transparent casing, but visible seams and scars arise that remain permanently visible

Engineering Contradiction:

Improveobject incorporationVSAvoidvisible seams

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The object is aligned and positioned on the first joint surface before the casing parts are brought together and fused. This preliminary positioning ensures the object is correctly placed before the sealing process begins, preventing the need to hold it from outside during fusing which would create visible seams

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The first joint surface and second joint surface are fused together under pressure and temperature to create a seamless union. The fusion process merges the two casing parts into a single transparent structure that encloses the object without visible seams or scars

Inventive Principle:

Principle #5Merging (Combining)

2Manufacturing precision

If the object is held from the outside during the fusing process, then the object can be positioned in the casing, but seams or scars arise that remain permanently visible

Engineering Contradiction:

Improveobject positioningVSAvoidvisible seams

Core Design Contradiction:

Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The object is aligned on the first joint surface and temporarily fixed by clamping before the fusing process begins. This preliminary fixation allows precise positioning to be achieved before the casing parts are brought together, eliminating the need to hold the object from outside during fusing

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The joint surfaces act as an intermediary mechanism for positioning and fixing the object. By aligning the object on the first joint surface and bringing the second joint surface against it, the object is securely positioned between the two surfaces during the fusion process without requiring external holding

Inventive Principle:

Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If the joint surfaces are subjected to pressure force and temperature for fusion, then the casing parts can be joined without visible seams, but air inclusions may form that compromise transparency

Engineering Contradiction:

Improvevisible seamsVSAvoidair inclusions

Core Design Contradiction:

Object-affected harmful factorsVSObject-generated harmful factors

Solution Approach 1:

The pressure force applied during fusion serves a dual purpose: it ensures complete contact and bonding of the joint surfaces to eliminate visible seams, while simultaneously compressing and eliminating air inclusions that would otherwise form during the heating and bonding process

Inventive Principle:

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

Solution Approach 2:

The application of temperature causes the joint surfaces to undergo phase transition to a softened state, enabling fusion. The pressure force applied during this phase transition ensures complete bonding while expelling air inclusions, resulting in a seamless and transparent joint

Inventive Principle:

Principle #36Phase transitions

AI summary

The invention relates to a production method for incorporating an object into a multi-part, transparent casing. According to the method, an object is aligned on a first joint surface of a first casing part and is pressed into said part using a second casing part with a second joint surface. The first joint surface of the first casing part and the second joint surface of the second casing part are then fused by pressure and temperature, forming a region between the casing parts that is devoid of a visible seam.
