Existing product integration
Existing XGRAPHENE Capsule products combine upper-cabin and lower-mattress graphene heating. Explore the system architecture and discuss OEM adaptations for your product.
Project snapshot
01 / Integration challenge
The existing Capsule is the starting point: review the shipped configuration and the interfaces your OEM adaptation would change.
The upper cabin and the lower mattress present different integration challenges. One follows the enclosure; the other combines heating with a supporting contact interface. The product also brings controls and additional functional modules into the same physical envelope.
A productive OEM discussion starts with the existing configuration: what fits your program, what needs adapting and which interfaces those changes affect.

These constraints come from the existing configuration itself — not from a failed prototype.
B1 / DUAL-ZONE GEOMETRY & POWER ALLOCATION
The upper cabin and the lower mattress differ in area, attachment and heat-loss conditions, so panel coverage and watt density must be set per zone. Heater temperature, inner-facing temperature, mattress contact temperature and cabin air temperature answer different questions — define which one the controller regulates before fixing the power split.
B2 / INDEPENDENT CONTROL LOOPS & MAIN BUSBAR
Independent regulation per zone avoids forcing both interfaces to one setpoint, but adds branch circuits, sensing and connectors. Branch current, cable ratings, contact resistance and the response to a single-zone fault are reviewed together; unequal branch loading shows up as local connector heating.
B3 / SEALED-CABIN PROTECTION & UNIFORMITY BOUNDARY
Inside a closed cabin, an insulating object or a changed liner reduces heat rejection, so reduced heat loss and the over-temperature response become the limiting case. Lamination pressure and liner replacement also change the thermal path: document them, define serviceable parts, and re-verify after maintenance.
03 / XGRAPHENE solution — 3-tier architecture
The existing product already combines enclosure, heater, facing and control. The three tiers below describe how those parts fit together for an OEM adaptation.
The upper assembly uses encapsulated flexible heating film that follows the available interior surface of the enclosure. The heated area is divided into an upper and a lower zone, each with its own power distribution and sensing, so the two interfaces can be regulated independently rather than driven by one shared setpoint. Dividing the surface adds connections, so branch current, cable ratings and single-zone fault response belong to the same circuit decision.
The heater is not a separate appliance: it is assembled into the cabin shell and the mattress. Layer roles below describe the integration path from the raw record.
| Integration layer | Role in the assembled product |
|---|---|
| Enclosure and panel carrier | Structural geometry and attachment points for the heating subsystem. |
| Encapsulated flexible heating film | Flexible heater with electrode interfaces and protective encapsulation fitted within the upper assembly. |
| Inner liner / facing | Thermal path between the heater and the intended internal surface. |
| Power distribution and sensing | Branch circuits, representative sensing, control and protective response. |
Functional integration roles based on the product library. They are not a manufacturing layer order, and they do not describe an exact lamination sequence.
The heating function is delivered by a graphene layer inside the encapsulated film, and far-infrared emission is a material-level property of that layer. No emissivity or wavelength figure is applied to this product: the NIQS film-sample emissivity report (2022)WT-HW-00529 describes a different graphene film sample and does not establish this configuration's optical or thermal performance.
Material-level figure; it does not establish field performance or biological efficacy.
04 / As-supplied configuration & verification
Configuration and method statements for the shipped assembly — not measured performance results. A customized build requires its own test records.
| Integration challenge | Physical mechanism to assess | Proposed verification | OEM design decision |
|---|---|---|---|
| Local overheating under changed heat loss | An insulating object or altered liner reduces heat rejection. | Assess defined abnormal coverage and liner configurations with reference sensors. | Operating envelope and protective response. |
| Hot connector or branch imbalance | Contact resistance or unequal branch loading. | Record current and connector temperature for each branch during representative operation. | Distribution layout, terminals and service access. |
| Thermal drift after assembly | Adhesive, contact pressure or panel tolerances change the thermal path. | Compare sample assemblies and repeat checks after defined environmental conditioning. | Assembly specification and inspection points. |
Existing product configuration with batch supply. Figures from the configuration describe the as-supplied assembly — they are not field performance, thermal uniformity or durability results. OEM changes to enclosure, materials, electrical layout and controls require their own validation scope and test records.

06 / Technical FAQ
Existing product and batch supply. Start with the available Capsule configuration. Agree the build and verification scope for your customized version.
The product library describes heating in both the upper cabin and lower mattress. These are two different thermal interfaces within one enclosed system.
Not necessarily. The upper assembly exchanges heat across the interior space, while the lower assembly includes a supporting mattress and contact-facing materials. Their area, attachment, heat loss and operating requirements must be considered separately.
Use the existing product as the starting point for an OEM review of enclosure geometry, heating areas, facing materials, electrical input and controls. Agree the configuration and verification scope before releasing the customized build.
A material result describes its identified sample and test conditions. Product evaluation also considers installed panels, the mattress, electrical distribution, temperature control and operation of the complete assembly.
