Abstract

Methods and apparatuses for disassembling components are described. An apparatus in accordance with an aspect of the present disclosure comprises a first component including a first adhesive interface, a second component including a second adhesive interface, a joint between the first and second adhesive interfaces, the joint comprising an adhesive bonding to the first adhesive interface and to the second adhesive interface, such that the first component and the second component are joined together, and at least one thermal element in the adhesive, wherein the at least one thermal element is configured to weaken the joint by heating the adhesive when an energy is applied to the thermal element.

First claim

What is claimed is:

1. An apparatus, comprising:
a first component including a first adhesive interface;
a second component including a second adhesive interface;
a joint between the first and second adhesive interfaces, the joint comprising an adhesive bonding to the first adhesive interface and to the second adhesive interface, such that the first component and the second component are joined together;
a plurality of thermal elements in the adhesive, wherein the plurality of thermal elements is configured to weaken the joint by heating the adhesive when an energy is applied to the plurality of thermal elements;
the second component comprising a retention feature configured to hold the first and second components together during a curing of the adhesive, wherein the retention feature comprises a plurality of pathways, and wherein each thermal element of the plurality of thermal elements is accessed through one of the pathways of the plurality of pathways; and
the first component comprising an alignment feature, wherein the alignment feature is configured to be coupled to the retention feature.

2. The apparatus of claim 1 , wherein the energy comprises at least a thermal energy or an electrical energy.

3. The apparatus of claim 1 , wherein the first adhesive interface comprises a tongue, and the second adhesive interface comprises a groove.

4. The apparatus of claim 3 , wherein the groove of the second component comprises a plurality of sections, and at least one thermal element of the plurality of thermal elements is in a section of the plurality of sections of the groove of the second component.

5. The apparatus of claim 1 , wherein each thermal element of the plurality of thermal elements is coupled to more than one pathway of the plurality of pathways.

6. The apparatus of claim 1 , wherein at least one of the plurality of thermal elements includes a wire.

7. The apparatus of claim 1 , wherein the alignment feature comprises a tongue or a plurality of segments spaced apart.
