Case studies

Client names stay private. Scope and constraints are stated.

Each profile gives the control target, the delivery scope and the program length; figures are rounded to protect the client.

Hospitality

Europe · Hotel group

One remote for three TV generations and a cleaning schedule.

A hotel operator was replacing room remotes across a mixed estate. Some rooms had older IR televisions, others had newer BLE set-top boxes. Housekeeping used a daily wipe protocol that had already damaged the previous handset’s legends.

The brief was not “design a remote”. It was “stop the replacement cycle and stop the front-desk calls”.

What we did. Sealed single-shell housing, double-shot legends, IR + BLE on one key matrix, five language variants loaded per property, and spares cloned from the same configuration record.

North America · Control platform

A white-label handset with a pairing flow guests cannot break.

A control platform wanted its own handset for installers and end users. The hard requirement was recovery: a handset that lost its binding had to be restored in the room, without a service call or a laptop.

The platform team owned the protocol. We owned the board, firmware integration and the pairing sequence around their service.

What we did. BLE + 2.4 GHz variant on a shared PCB, white-label firmware, OTA through the hub, an installer key map and a documented recovery sequence tested with a handset that had been deliberately unbound.

Europe · Adjustable bed brand

Low-power control for a product used twice a day, for years.

An adjustable-bed brand had a working RF receiver and a handset that users found hard to read in bed. The new handset had to keep the receiver, improve the key feel and meet a battery target measured on a duty cycle, not estimated from a datasheet.

The existing enclosure tooling could not accommodate the larger keys, so the program included a new mold and two tooling rounds.

What we did. New ID with large tactile groups, held-key logic defined with the motor controller, 433 MHz link matched to the existing receiver, and a duty-cycle rig used to verify the battery target before release.

More programs

Shorter profiles from other environments.

These programs are shorter because less of the brief is public.

Two remotes into one
Streaming hardware

Two remotes into one

IR + BLE handset for a streaming device and the installed TV base. The program started with code coverage and ended with a 38-key map across three device groups.

Scope: code library, key map, certification support

Simplified control for residents
Care environment

Simplified control for residents

A care operator needed fewer keys, larger legends and a handset that staff could clean and replace quickly. The key map was reduced and the battery door was tooled for controlled access.

Scope: key-map research, sealing, replacement program

Rollout across mixed properties
Hospitality

Rollout across mixed properties

A management group rolled out one handset across properties with different TV brands and languages. Configuration records were kept per property so spares matched the room.

Scope: batch configuration, language variants, spares

Confidentiality

What we can share.

Client names, exact model codes, volumes and prices stay with the client. What remains is the part a buyer can actually use: the control problem, the constraints and the delivery scope.

If a figure would identify a client, it is rounded or replaced with a range.

What a reference call can cover

Reference calls are arranged with client consent during an active evaluation.

  • Program approach and stage discipline
  • How issues were found and resolved
  • What the client’s team had to own
  • Schedule reality versus the original plan
  • Whether they would run the program again

Your brief does not have to match one of these.

Most programs are a mix: one environment, one constraint we have not seen, and a launch date. That is a normal starting point.
