The following does not constitute legal advice, and I am not a lawyer. The safest approach to copyright infringement is to obtain authorization from the right holder in advance. The following is for reference only to help you understand some general principles, but you should seek professional legal advice in specific situations: 1. Confirm the status of the work and the scope of copyright • First determine whether the other party's design elements are protected by copyright. If the element is in the public domain, or its creator has clearly adopted a permissive license (such as Creative Commons), then the risk of using it is relatively low. • Note that sometimes seemingly ordinary designs may be protected because of originality, so it is necessary to carefully distinguish which parts are "common forms" for reference only and which constitute original expressions. 2. Borrow rather than simply copy • Analyze the core ideas and expressions of the design, and then consider how to "re-create". Simply changing the color, proportion or partial details is often not enough to avoid the risk of infringement; only after a comprehensive transformation and giving the work new ideas and style can it be more likely to be regarded as an independent creation. • In the process of innovation, use the original design as inspiration rather than directly copying it. Whether the adapted work constitutes a reasonable "secondary creation" depends on the specific circumstances. 3. Fair use and areas of ambiguity • In some jurisdictions, the law provides that some works can be used without authorization under fair use (or fair dealing). However, the scope and standards of fair use are often highly dependent on the facts of the case (such as the purpose, nature, proportion of the work used, and the impact on the market), so be sure to assess the risks before use. • Research on historical facts (such as academic citations, comments, satire, etc.) can sometimes constitute fair use, but the boundaries between design works are not always clear, so it is necessary to assess in advance for the sake of caution. 4. Avoid direct copying of "derivative works" • Even if the original work is modified, if the identifiable creative part is still derived from the original work, it may be considered infringement. When conceiving, ensure that the elements used are substantially and creatively reworked, rather than just superficial adjustments. • Completely deviating from the characteristics of the original work and ensuring that the new design contains sufficient originality can reduce the risk of infringement. 5. Risk self-assessment and legal consultation • Before trying any marginal operations, evaluate whether your use may cause legal disputes, as well as the possibility and consequences of damage. • To reduce potential risks, it is best to consult a professional IP lawyer to understand local legal practices and court cases, as the application of "workaround techniques" may vary greatly in different legal systems. In short, any practice of using other people's design elements without authorization poses a potential risk of infringement. The above suggestions are just a direction for thinking and cannot replace legal advice in specific situations. In the long run, ensuring that the design is sufficiently original and innovative, and respecting and protecting the intellectual property rights of others, is usually the best strategy to reduce the risk of disputes.
