Analogue-and-Digital-DesignElectronic systems play a vital role in various industries, from healthcare to transportation, and safety is a paramount concern in their design. While off-the-shelf devices may meet some requirements, they can sometimes fall short in terms of tailored functionality, performance, and reliability. Bespoke electronic devices offer a solution, but they come with unique challenges, especially regarding safety. We are going to take a closer look at the importance of safety in custom electronic design, discussing industry standards, design strategies, testing, quality assurance, manufacturing considerations, and the intersection of design and manufacturing. All of which are incredibly important to DSL.

Safety Considerations in Electronic Design

Ensuring safety in electronic design is crucial to prevent hazards and errors that can have severe consequences. Processor design must avoid hardware failures that can lead to system crashes, data corruption, or security breaches. Analogue and digital design must be properly implemented to prevent interference and voltage spikes.

Operating systems and firmware must manage resources and interactions between hardware and software to prevent security threats. Software design must also consider safety to prevent unexpected behaviour, data corruption, or system crashes. Industry sectors where safety is critical include healthcare, aerospace, automotive, industrial automation, and energy production. Engineers must follow stringent safety guidelines and best practices throughout the design process to mitigate risks.

That’s a lot of different areas of safety to consider!

Challenges in Custom Electronic Design

Custom electronic design faces challenges in balancing innovation and safety. Designers must integrate new technologies while ensuring compliance with safety standards. Processor design must optimise performance while minimising power consumption and heat generation. Analogue and digital design must mitigate noise and interference. Operating systems and firmware must efficiently manage resources and provide user-friendly interfaces. Software design must create intuitive user interfaces, and robust algorithms, and ensure data security. All these elements must work together seamlessly to create innovative, safe, and reliable custom electronic devices. This is something that the team at DSL have had extensive experience in and use our knowledge and expertise to overcome challenges on a daily basis.

Compliance with Industry Standards

Compliance with industry standards is a crucial aspect of electronic system design in the UK. Key industry standards include IEC 62368-1 for audio/video and information technology equipment, and ISO 13849-1 for machinery safety. These standards outline specific requirements for the design, construction, and testing of electronic systems to ensure safety and prevent hazards.

Complying with these standards can be challenging in bespoke designs, which are tailored to meet specific customer requirements. Unique design features or novel applications may not fit neatly into existing standard frameworks, requiring designers to find creative solutions that still meet safety requirements. Custom designs may involve non-standard components or materials, necessitating additional testing and evaluation to ensure conformity with industry standards.

Designing for Safety

Designing for safety involves incorporating safety considerations into the design process to minimise the risk of injury or harm to users and stakeholders. This includes strategies such as:

  • Conducting risk assessments to identify potential hazards and evaluating their likelihood and impact.
  • Implementing safety features and controls, such as alarms, warnings, and emergency stop mechanisms.
  • Designing products and systems that are easy to use and understand, with clear instructions and feedback.
  • Testing and validating designs to ensure they meet safety standards and regulations.

Testing and Quality Assurance

Testing and quality assurance are crucial for ensuring the safety of electronic systems and should form part of every electronic design project. Different testing methods like functional, durability, and environmental testing help identify potential hazards and weaknesses. Quality assurance processes, such as design document reviews, inspections, audits, and testing, verify that the system meets safety standards and regulations. Thorough testing and quality assurance build trust and credibility, protecting users from potential hazards and helping manufacturers maintain a positive reputation. Investing in comprehensive testing and quality assurance processes is essential for delivering safe and reliable electronic systems.

The combination of design and manufacturing is critical in ensuring the safety of electronic devices. Designers must consider manufacturing processes and limitations when creating their designs, while manufacturers must adhere to safety standards and regulations during production. Challenges arise when producing bespoke electronic devices, as unique designs and custom components may require specialised manufacturing processes, potentially compromising safety. Quality control measures, such as inspection and testing, are essential in detecting defects and ensuring compliance with safety standards. Effective communication between designers and manufacturers is necessary to address any safety concerns and ensure that safety requirements are met throughout the manufacturing process. By prioritising safety in both design and manufacturing, companies like DSL can work with their clients to produce high-quality, reliable electronic devices that meet user needs while minimising risk.
