Cell Phone/Desk Phone - Hybrid

Human: Cell Phone/Desk Phone - Hybrid The idea for this innovative design emerged a few months ago, fueled by my personal experience working for a company that abandoned their PBX phones in favor of mobile devices. Missing my trusty desk phone, I devised a clever concept to merge the convenience of a cell phone with the comfort of a full desktop phone. This design bypasses complex Bluetooth technology and takes advantage of the phone's 3.5mm jack, transforming it into a versatile charging base and phone stand that's both portable and lightweight. Perfect for impromptu trips to the meeting room or dynamic office environments. The base was designed specifically for my office-issued iPhone SE and features two interchangeable front covers to accommodate this phone with and without its case. The front cover snaps securely into place, surrounding the power/earphone jacks, while a cutout on the face allows for easy removal and a large slot in the back enables quick cable passage. The stand and handset rest are fitted using a clever peg-and-hole system that also extends slightly into the base, allowing for flexible use with or without adhesive. This design boasts ambidextrous handset placement, making it suitable for both left- and right-handed users. The handset was crafted from repurposed parts salvaged from an old office phone, including the Mic/Speaker unit and RJ9 jacks. A small compartment in the back of the MIC rest houses a RJ9 jack, enabling modular design flexibility. Simply plug in any RJ9 headset or your preferred handset to achieve the same result. The wiring was a straightforward process that leveraged the 4-pin 3.5mm headphone jack and a set of ear pods provided with the phone. However, I encountered an issue when attempting to solder the cloth-cored wiring within the 3.5mm cable. To overcome this challenge, I carefully exposed the 3.5mm jack, removed the original wiring, and directly soldered new wires. Out of the four pins, only Mic, Left, and Ground are utilized – both for the mic/speaker unit and the ear pods. Initially considering engineering a hook switch for the headset, I ultimately decided to harness the phone's touchscreen for all controls. This is my first multi-part assembly in Fusion, and I'm thrilled that I persisted with the design process over several months. This concept not only boasts an attractive appearance but also delivers impressive functionality. It's my pleasure to share this innovative design with the Thingiverse.com community. Enjoy!
