Solution 04 — Smart Furniture & Motion
Control for something that moves for ten years.
Beds, recliners, shades and adjustable desks are used every day and serviced almost never. The handset has to be ergonomic, low-power and resistant to the wrong button being held down.
The brief
The remote outlives the warranty, and everyone knows it.
A furniture handset is bought once and used for a decade. It sits in a drawer, falls between cushions and gets pressed by accident. The receiver is usually fixed long before the remote is designed.
So the engineering order is reversed: start with the receiver and the movement profile, then size the radio, the key feel and the battery around them.
- Radio range quoted in open air, not through a mattress or frame
- Held-key behavior that keeps the motor running after release
- Battery life estimated from standby current alone
- Keys too small for use in bed or with limited hand strength
- A new handset that cannot bind to the installed receiver
What we build
Four decisions that keep the handset working in year five.
Every item is verified with a test that can be repeated on production units, not only on a golden prototype.
Range where the furniture is
We test through the actual frame, upholstery and room layout, not on a bench. If the link is marginal, we change the antenna or the receiver placement before changing the enclosure.
Movement stops on release
Held-key logic, timeouts and repeat behavior are defined with the motor controller. A dropped or jammed remote must not leave the mechanism driving.
A battery budget, calculated from the load
We model sleep current, wake behavior and transmission time against your daily-use assumption, then state the target and the test method. Actual life is measured on a duty-cycle rig.
Keys for a hand at rest
Key size, spacing, travel and actuation force are chosen for use in bed or from a recliner. Legends stay high-contrast and tactile grouping marks the direction keys.
Recommended control stack
The receiver decides more than the remote.
If the furniture already has a receiver, the handset must match it. If the electronics are new, we can propose a link that fits the movement profile and the target battery life.
| Layer | Standard path | When it becomes custom |
|---|---|---|
| Link | 433 MHz or 868 MHz RF with fixed or rolling code | BLE for app control or multi-device scenes |
| Pairing | Receiver learn button plus handset code | QR or app-based binding, multi-handset groups |
| Power | 2× AAA, no backlight | Rechargeable dock, backlit keys, haptic feedback |
| Validation | Range, key life and duty-cycle test | IP rating, chemical resistance, extended temperature |
Project profile
One electronics platform, four furniture brands.
An adjustable-furniture manufacturer needed branded handsets for several product lines without maintaining four separate control designs. The shared platform carried the radio and firmware; the enclosure and key map carried the brand.
Shared PCB and firmware
Matched to existing receivers
Measured on duty-cycle rig
Receiver sample to pilot build
