Implemented across 2 products.• Originator of a patent pending design to further deter liquid ingress without increasing device size, process time, part count & process steps.• initiated an accurate tolerance stack to finalise dimensions of the new stretch-to-fit mic boot for acoustic sealing. No design change from soft tool to production tool.• initiated & implemented a counterproposal for a portfolio solution. Comprises of a non status quo design of a child safe batt door. Savings up to: 3 product x2 tooling +3 masking fixture =9 investments. New concept reduced steps to activate child safety from 4 to 1 at dispenser end. Customer also does not need a tool to open the door to change the batt. Child safe feature remains active when batt door is partially opened at OFF mode.• Spearheaded & worked with supplier to improve shock performance of a critical component by 20%. Gained leverage in the negotiation to implement across 4 models without increasing part cost.SIGNIA Motion C&G P:• created architecture layout & solutions.• 1st BTE developed & launched with a new galvanic charging system.• Designed mic suspension/boot with good acoustic performance. Design referenced by BTE SP.• Mentored junior engineers.• BOM, 3D & 2D includesPCB outline, PCB/SMA strip layout, wire dressing.• Angular and linear tolerance analysis.• came up with a statistical approach to evaluate the risk of acoustical failure due to dropping of device.• worked with a cross-functional team to create a working system from scratch.• Main author of a granted patent design for a two-stage sealing at the two-part interface to prevent o-ring extrusion.• Designed the modular mini sealing of charging contact to fit across 4 models. The stretch-to-fit design removed the need for another part/glue to hold it in place against handling. Show less

Led a team of up to 4 Engineers during the architecture phase for 3 BTE projects:• 2 developed into full projects. • Designed common parts across multiple platforms, led and co-developed a sound damping feature for the tact switch.• Developed a design with a higher stopping torque for both ear hook and thin/life tube against overturning and a patented concept for its acoustical sealing.• Worked out a method to analyze the gap for fingernail access between the hsg part & switch… Show more Led a team of up to 4 Engineers during the architecture phase for 3 BTE projects:• 2 developed into full projects. • Designed common parts across multiple platforms, led and co-developed a sound damping feature for the tact switch.• Developed a design with a higher stopping torque for both ear hook and thin/life tube against overturning and a patented concept for its acoustical sealing.• Worked out a method to analyze the gap for fingernail access between the hsg part & switch upon full activation to allow tool-free removal of the rocker switch as a new design requirement.• This method, the design of common parts, the sound damping feature and the stronger stopper served as design references for the 4th BTE project. • Managed & coordinated the mechanical aspect of the 3 projects.Part of the architecture team for the Signia Xperience RIC (Receiver-in-Canal) 312:• Main contributor for the alternate concept of possible component placement.• Designed the -ve terminal battery contact with full tolerance analysis & bending beam formulas to achieve the lowest working height in Sivantos history and an improved development efficiency (lesser iterations with simulation engineer & no re-designing needed until mass production stage).• Calculated the minimum angle for the on-off mechanical feature on the battery door based on full tolerance analysis & achieved similar development efficiency.• Taught the designer for the +ve terminal contact on where to indicate tolerance control, how to perform tolerance analysis & apply formulas of a bending beam.• Shared with the project team how to design the holding feature at the PCB end for a good connection with the loading spring contact of the telecoil. Referencing from my previous Signia Pure 13 Nx project.• Shared also with the team on the application of bending beam calculation, angular and linear tolerance analysis on the tele-coil contact spring to improve development efficiency.
