Load-bearing tests aren't just about stacking weights until something breaks. We designed a step-by-step process to mimic real-world scenarios, from light, constant pressure to sudden, short-term impacts. Here's how we did it:
1. Static Load Test (Continuous Pressure)
First, we placed the frame on a non-slip wooden platform (the most common surface for home use) and applied weight evenly across its top edge and base. We started with 500g (about the weight of a large hardcover book) and increased by 500g every 30 minutes, measuring deformation (how much the frame bent or warped) with the height gauge. We stopped when we observed permanent damage (cracks, splits, or the frame no longer returning to its original shape after removing the weight).
2. Dynamic Load Test (Sudden Impact)
Next, we tested how the frame handles sudden, short-term pressure—like a child leaning on it, a bag accidentally dropping on it, or a customer resting their elbow on a retail counter with the frame. Using a calibrated pendulum, we dropped a 1kg weight (the weight of a standard laptop charger) from heights of 10cm, 20cm, and 30cm onto the frame's acrylic border and screen area. We repeated this 10 times for each height to simulate repeated impacts.
3. Edge Load Test (Uneven Pressure)
Acrylic frames often have thin, delicate edges. We applied pressure to the corner of the frame (the weakest point) using a 2kg weight (about the weight of a small toaster) placed on a 5cm x 5cm metal plate to concentrate the load. We left this in place for 24 hours to see if the corner cracked or the frame tilted.
4. L-Base Stability Test
Since this frame uses an

base, we tested how much lateral force (sideways pressure) it could withstand before tipping over. We attached a string to the top of the frame and pulled it horizontally with the digital force gauge, increasing tension until the frame began to lift off the platform. This mimics someone bumping into the frame or a pet brushing against it.
Note: Throughout all tests, the frame was powered on to ensure that structural stress didn't affect internal components (e.g., the screen, battery, or circuit board). We checked for screen flickering, unresponsive touch controls, or power failure after each test phase.
