WALKER: A LOW-COST FOLDABLE ROLLATOR WALKER TO HELP THE ELDERLY REGAIN WALKING INDEPENDENCETHE AIM OF THIS PROJECT IS TO CREATE AN AFFORDABLE, FOLDABLE LIGHTWEIGHT WALKER THAT CAN BE USED ACROSS ALL TERRAIN, INCLUDING CLIMBING CURBS AND STAIRS CALLED THE DU BAOZHU (D.B.Z.) WALKER. A 1:8 CAD DESIGN OF THE WALKER WOULD FIRST BE 3D PRINTED TO SEE IF ANY ADJUSTMENTS NEED TO BE MADE. AFTER MAKING A SECOND PROTOTYPE, THIS TIME A 1:1 SCALE, ADDITIONAL FEEDBACK AND TESTING WILL BE CONDUCTED. FINALLY, A USABLE PROTOTYPE OF THE ACTUAL WALKER WILL BE TESTED BY A GROUP OF ELDERLY BETWEEN THE AGES OF 50 TO 60 TO SEE IF ANY FINAL ADJUSTMENTS NEED TO BE MADE. AFTER THE IDEA IS DEVELOPED, THE WALKER WILL BENEFIT THE ELDERLY POPULATION IN GENERAL, AND IT CAN BE USED BY OTHER ELDERLY CARE ORGANIZATIONS AND HOSPITALS FOR CONVENIENT TRAVEL.DU BAOZHU (D.B.Z.) WALKER IS DESIGNED TO BE AN ALL TERRAIN WALKER WITH A SEAT. ALUMINUM IS USED AS THE MAIN MATERIAL OF THE WALKER TO KEEP IT LIGHTWEIGHT, AND IT IS FOLDABLE TO MAKE IT EASY TO CARRY FOR TRAVEL. THERE ARE SPECIAL WHEEL DESIGNS IN ORDER TO MINIMIZE THE SHOCK GIVEN TO THE WALKER AND SHOCK ABSORBERS ARE ALSO APPLIED TO THE WHEELS. THERE IS NO CONTROL PAD ON THIS WALKER, WHICH MAKES IT EASIER FOR THE ELDERLY TO USE ON THEIR OWN. THE IDEAL PRICE POINT FOR THIS NEW WALKER IS AROUND $60, SINCE THAT IS THE AVERAGE PRICE FOR THE MOST BASIC WALKER. SINCE THE MOST STANDARD WALKER WEIGHS AROUND 15 POUNDS, THE D.B.Z. WALKER WILL AIM TO BE AROUND THAT WEIGHT 5 POUNDS, MAKING ITS MAXIMUM WEIGHT 20 POUNDS. THE FIRST PROTOTYPE OF THE D.B.Z. WALKER WILL BE ONE-EIGHTH THE SIZE OF THE REAL WALKER AND CADED USING FUSION 360. ALL THE CORE COMPONENTS OF THE PROTOTYPE DESIGN WILL BE INDIVIDUALLY CADED INTO SEPARATE COMPONENTS. NEXT, THE COMPONENTS WILL BE ASSEMBLED IN ORDER TO ASSESS THE DESIGN. BASED ON THIS MINIATURE PERFORMANCE, ALTERATIONS WILL BE MADE AS NEEDED. THE SCALED DOWN VERSION OF THE WALKER WILL BE USED TO PROVE THE EFFICIENCY OF THE TRIANGULAR WHEEL. ANY NECESSARY MODIFICATION OF THE WHEEL WILL BE DONE BASED ON THE RESULT OF TESTS. A LIFE-SIZE VERSION OF THE WALKER WOULD THEN BE CADED AND ASSEMBLED ACCORDING TO THE MODIFICATIONS MADE IN THE ONE-EIGHTH SCALED VERSION. THIS WALKER WOULD BE ASSESSED AGAIN IN ORDER TO DETERMINE OTHER DESIGN CHANGES TO IMPROVE THE WALKER.IN THE FUTURE, A SECOND PROTOTYPE WILL BE MADE IN ORDER TO ADJUST ANY FLAWS THE PREVIOUS VERSIONS HAD. THE COMPONENTS WOULD BE DIVIDED INTO TWO GROUPS: ONE GROUP THAT CAN BE FABRICATED IN A FAB LAB AND ONE GROUP THAT NEEDS TO BE SOURCED TO THIRD PARTIES. THE FRAME WILL BE SOURCED DUE TO THE CUSTOMIZATION OF THE D.B.Z. WALKER FRAME. THE WHEELS WILL ALSO BE SOURCED BECAUSE OF ITS UNIQUE DESIGN AND THE COMPLEXITY OF ASSEMBLING. THE SEAT, SHOCK ABSORBER AND THE BRAKES CAN BE OBTAINED FROM GEAR STORES AND CAN BE ASSEMBLED IN A FAB LAB.IN ORDER FOR THE WALKER TO TRAVEL SMOOTHLY ON UNEVEN SURFACES, A TRIANGULAR WHEEL IS DESIGNED TO HELP THE WALKER CLIMB OVER CURBS AND ROCKS. THIS WHEEL SYSTEM CONSISTS OF ONE MAIN STABLE WHEEL AND THREE ROTATING WHEELS. THE THREE WHEELS WILL BE ATTACHED TO THE MAIN WHEEL, THE ANGLE BETWEEN EACH WHEEL WILL BE 60. WHEN THE WALKER IS TRAVELING ON A FLAT SURFACE, TWO WHEELS WILL TOUCH THE GROUND FOR THE WALKER TO MOVE STABLY. WHEN THE WALKER TOUCHES A CURB, THE WHEEL ON THE GROUND WILL BECOME A POINT THAT SUPPORTS THE WHOLE WALKER. THE USER NEEDS TO PUSH THE WALKER, AND THE MAIN WHEEL WILL ROTATE DUE TO THE FORCE GIVEN BY THE USER. THE WHEEL IN THE AIR WILL TOUCH THE GROUND AND THE WALKER WILL CLIMB UP THE CURB. TEN YEARS AGO, A GROUP FROM VCU DID A SIMILAR PROJECT OF A STAIR CLIMBING WHEEL. IN THEIR PROJECT, THEY MADE A WALKER THAT CAN CLIMB UP AND DOWN STAIRS MORE EASILY USING A SIMILAR TECHNIQUE TO THE TRIANGULAR WHEEL SYSTEM. THIS SHOWS THAT THE TRIANGULAR WHEEL IS A FEASIBLE PROJECT. THE WALKER WILL BE BUILT AS A REAR WHEEL DRIVE WALKER BECAUSE COMPARED TO FRONT WHEEL DRIVES, REAR WHEEL DRIVES HAVE SMALLER TURNING RADIUS, AND THUS MAKES IT EASIER TO TURN.
