What are your mechanics problem-solving heuristics?

Daily meeting to get any information or problem among the mechanic and solve it. If need more attention, higher level management in to involve to expedite to solve the issue yo avoid any delay.

An automotive company is refining its electric sedan, which currently offers a 250-mile range from a 75 kWh battery, aiming for 350 miles without altering battery size, weight, or 0-60 mph acceleration. Key areas of focus: 1. BMS: Transition from a conventional system to an advanced BMS for enhanced charge/discharge optimization and battery longevity. 2. Aerodynamics: Redesign for a Cd under 0.24, with potential adjustments to the grille and underbody airflow. 3. Tires: Shift to custom low rolling resistance tires. 4. Braking: Improve regenerative braking to recover over 70% energy. 5. Motor & Drivetrain: Aim for motor efficiency over 90% and reduce drivetrain losses. 6. Systems: Adopt adaptive HVAC and energy-efficient electronics.

To me the most helpful mindset for problem solving is to let go of everything you think you know. Get as much information as you can and be sure your data is scientifically correct. The information gathering stage is the most important part of your problem solving process. Let go of all emotion and preconceived ideas you may have about the problem and see the problem clearly with a fresh perspective.

Even if there is a rush get your ducks in a row first this will put you on a good path. You my find one person idea of the problem is or has a short cut to fixing it but it will just come back down the road. Make to get input from all the players not just the ones that want something fixed, changed or done thier way.

TO SOLVE A MECHANICAL PROBLEM IS TO FIND OUT THE ROOT CAUSE OF THE PROBLEM AND REPLACE THE DEFECT EQUIPMENT AND SOLVE THE ROOT CAUSE OF IT AO THAT IT WONT HAPPEN AGAIN..

Having all your information in a easy to understand visual form can help you gain perspective and see the problem all at once. Drawing a visual representation of the problem will assist in fully understanding the problem an see from a holistic perspective.

Our task centers on an electric sedan, distinguished by its sleek design and powered by a 75 kWh Lithium-ion battery. Presently, on a full charge, it promises a journey of 250 miles. The ambition? Stretch this journey to 350 miles, without meddling with the battery's dimensions or mass. But there's a twist: this sedan boasts a rapid acceleration, racing from 0-60 mph in under a mere 6 seconds. We can't let that slip. Beyond mere numbers, this is a tale of balancing efficiency with performance. It's a quest for innovation, ensuring the sedan remains a top contender amidst the electric vehicular evolution, satisfying both the eco-conscious and the speed enthusiasts.

"If you can't draw it, you can't build it". This was the mantra of my High School Shop Teacher, and it has served me well for over 40 years. It makes you think through the problem and helps focus on the different aspects of the project.

There are some vehicles with a lot of complicated timing marks,so if one is a novice He/She need to draw a diagram so that when the marks has been ultered the diagram will come in handy when it's time to rearrange the machine

Actually I believe that having all the information available is vitally important to fully understand and solve a problem. Simplifying the data visually and numerically can assist getting you started with the problem solving process.

To streamline our analysis, certain car aspects are simplified and approximated: Battery: Only 90% of the 75 kWh battery, or 67.5 kWh, is usable due to safety and longevity, serving for propulsion. Energy Consumption: Preliminary tests show the car uses 67.5 kWh over 250 miles, indicating an average consumption rate. Aerodynamics: Keeping other factors constant, range is approximated as inversely proportional to the drag coefficient. A lower drag coefficient boosts range. Rolling Resistance: Assumed constant and optimized for the vehicle. These approximations help focus on key variables to enhance performance.

To enhance range without changing battery size/weight, efficiency improvements are key. Methods include: A - Aerodynamics: Refine design elements like the grille, wheel arches, and underbody to decrease drag. B - Regenerative Braking: Improve energy recovery, considering advanced materials or control techniques. C - Weight Distribution: Adjust distribution for better stability and energy use, especially during varied driving conditions. D - Tires: Partner with manufacturers for custom tires that reduce rolling resistance but maintain grip. E - Drivetrain: Adopt a more efficient drivetrain to minimize energy losses.

Back in the days mechanics used to be difficulty because of so many sensors they put on vehicles, but in this era of technology, mechanics has been simplified to a level where diagnosis machines has been introduced and it kinda makes it simple to work on vehicles.

To validate post-change results: - PRD Testing: Measure the car's new range in actual driving conditions, aiming for 350 miles or more. - Performance: Ensure the car hits 0-60 mph in under 6 seconds, balancing efficiency and speed. - Consistency: Confirm consistent increased range across different tests and driving scenarios. - Safety & Reliability: Changes, particularly in systems like regenerative braking, should retain vehicle safety and reliability. - Comparison: Contrast the updated model's metrics with the previous version to confirm and measure enhancements.

I have always said this. A mechanic and a Doctor they are almost the same. Before the doctor give you medication they always ask about your sickness,same as a mechanic before you work on some ones vehicle one needs to how the problem developed or what really happened to the vehicle.

It's quite easy, Just read the question we'll . Draw the diagram, mark the force , Then to the law of conservation of energy, whether it's Statics or Dynamics .
