Abstract

Technologies are generally described for providing inductively removable assembly bonding. Inductive elements may be placed strategically at bonding locations between two or more coupled components. At disassembly time, the elements may be heated through Radio Frequency (RF) energy causing the bonds to break and components to separate. For example, inductive elements placed near plastic stake bonds between dissimilar materials in an electronic device may be employed to separate the dissimilar materials during a recycling process. According to some examples, the elements may also be heated through a directly applied electric current via a network of connections designed into the assembly.

First claim

What is claimed is:

1. A system to facilitate disassembly of an item that includes two or more attached components, the system comprising:
a controller module adapted to determine one or more of a level and/or a duration for application of RF energy to the item that includes two or more attached components, wherein the two or more attached components are attached through stake joints embedded with inductors that are configured to generate heat reactive to the RF energy such that the stake joints are deformed;
an RF energy source adapted to wirelessly apply the RF energy to the item such that the stake joints deform in response to the RF energy; and
an agitation module adapted to agitate the item such that the components are detached after the stake joints deform in response to the RF energy.

2. The system according to claim 1 , further comprising:
a grouping module adapted to group a plurality of separated components made of dissimilar materials in respective groups.

3. The system according to claim 1 , wherein the RF energy source is adapted to at least one of:
generate an RF field directed at the item; and
apply an RF current to a network of connections embedded into the item connecting to individual inductors.

4. The system according to claim 1 , wherein the inductors are coils, and wherein one or more of: a size, a material, a shape, and/or a thickness of the inductors s determined based on one or of: a size, a shape, a material, and/or a thickness of bosses employed to form the stake joints.

5. The system according to claim 1 , wherein the stake joints include one or more of plastic, polymer, ceramic, and a composite material.

6. The system according to claim 5 , wherein one or more of: a size, a material, a shape, and/or a thickness of an inductor is determined based on one or more of: a size, a shape, a material, and/or a thickness of a stake joint to which the inductor is embedded.

7. The system according to claim 5 , wherein at least a portion of the stake joints are embedded with a plurality of inductors.

8. The system according to claim 1 , wherein the controller module is further adapted to:
adjust one or more of the level, a frequency, and/or the duration of the RF energy based on one or more of: a material, a shape, and/or a thickness of the inductors in an assembled item and one or more of: a size, a shape, a material, and/or a thickness of the stake joints in the assembled item.

9. The system according to claim 1 , wherein the agitation module is adapted to agitate the item through one or more of mechanical agitation and/or magnetic agitation.

10. The system according to claim 1 , wherein the system is part of a recycling facility.

11. The system according to claim 1 , wherein
a plurality of embedded bosses are positioned to fit into holes in the components; and
a second RF energy is applied to the item such that the embedded bosses are deformed creating a stake joint between the components, wherein the stake joint is deformable in response to a first RF energy, which is different from the second RF energy.

12. The system according to claim 1 , wherein the components are further attached to the item by one or more of:
aligning holes in two or more components and inserting a boss to the holes for a tight fit; and
aligning holes in one or more components with a boss integrated into another component and inserting the boss to the holes for a tight fit.

13. The system according to claim 1 , wherein the RF energy is applied to the item by generating an RF field.

14. The system according to claim 13 , wherein a watt form of the RF field is adjusted based on a predefined period, wherein the waveform includes one or more of a pulse waveform, a square-wave waveform, a ramp up waveform, a ramp down waveform, a triangle waveform, and/or a sine-wave waveform.

15. The system according to claim 13 , wherein a waveform of the RF field is adjusted based on safety considerations.

16. The system according to claim 13 , wherein the RF field is generated from a source that is coupled to an assembled item.
