3 Helbling Sustainable Electronic Product Design
Radical visions for future Consumer Products: Initial Question. How might we design consumer products that people love, keep, repair, and pass on – while minimizing their environmental footprint? Background & Current Situation Consumer products such as coffee machines, kitchen appliances, or small household devices are often designed for short lifecycles. Driven by cost pressure and fast-changing trends, many of these products are built with limited durability, low repairability, and materials that are difficult to recycle. As a result, they are frequently discarded after a relatively short period of use, contributing significantly to waste and CO₂ emissions. At the same time, affordable and convenient products remain highly attractive to consumers. This creates a key challenge: how to reconcile sustainability, durability, and circularity with cost and user expectations.

SQLite provides an excellent development alternative for applications that are predominantly read-only or require a smaller installation footprint. As with all database servers, though, there are some differences that are specific to SQLite that you should be aware of. Substring matching and case sensitivity¶
For all SQLite versions, there is some slightly counterintuitive behavior when attempting to match some types of strings. These are triggered when using the iexact or contains filters in querysets. The behavior splits into two cases:
-
For substring matching, all matches are done case-insensitively. That is a filter such as filter(name__contains="aa") will match a name of "Aabb".
-
For strings containing characters outside the ASCII range, all exact string matches are performed case-sensitively, even when the case-insensitive options are passed into the query. So the iexact filter will behave exactly the same as the exact filter in these cases.
