Concept Development of Recline Functionality in CRS
(2026) MMKM10 20261Innovation
- Abstract
- This master’s thesis was done in collaboration with Thule Group during the spring of 2026. The purpose was to perform a concept development process in Child Restraint Systems (CRS), more commonly known as child car seats. These products are strictly related to crash safety as well as child ergonomics. Therefore, installations of CRS are important to ensure correct system status, meaning that the products included are secured and properly placed in the car. The goal of the project was to develop a concept that ensured that the CRS recline angles were within a uniform range across a variety of car seat geometries, while enabling installation in a slope as well as communicating clear feedback and guidance to users handling the product.

The purpose was to perform a concept development process in Child Restraint Systems (CRS), more commonly known as child car seats. These products are strictly related to crash safety as well as child ergonomics. Therefore, installations of CRS are important to ensure correct system status, meaning that the products included are secured and properly placed in the car. The goal of the project was to develop a concept that ensured that the CRS recline angles were within a uniform range across a variety of car seat geometries, while enabling installation in a slope as well as communicating clear feedback and guidance to users handling the product.
The development of the concept followed the principles of the Double Diamond design process including the phases Discover, Define, Develop, and Deliver. The research included a questionnaire, observations, a benchmark, and stakeholder insights. The data collected was analyzed through a thematic analysis. This analysis, combined with design opportunities that aligned with stakeholder insights, was used to define customer needs, requirements, and the problem definition.
Based on the findings, an iterative concept development process followed where ideas as sketches, mock-ups, and prototypes were evaluated and iterated continuously until the final concept was discovered. The process had two phases, a mechanical- and a user experience concept development. The result was a 3D printed prototype on a scale of 1:1 of a tilt-adjustable child car seat base with sensory feedback as well as a prototype of an app, which guides the user to perform the installation. The systems were connected by electronics, which included an angle sensor, a microcontroller, and LED lights. (Less)
