Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If handheld color measuring devices are designed with separate accessories for different measurement tasks, then measurement versatility is improved, but device complexity and weight increase
Solution Approach 1:
The patent implements a universal measuring device with a single optical measuring unit that can perform multiple measurement tasks (monitor measurement, projection surface measurement, and ambient light measurement) by repositioning the measuring unit to different positions on the device housing, eliminating the need for separate accessories for each measurement type
2Adaptability or versatility
If handheld color measuring devices include all necessary components for autonomous operation, then functionality is improved, but weight and portability worsen
Solution Approach 1:
The patent achieves functional completeness through a single multi-functional measuring unit that can perform all required measurement tasks (monitor, projection surface, and ambient light measurements) by repositioning, eliminating the need for multiple separate functional components and reducing overall device weight
3Adaptability or versatility
If the measuring unit is repositionable for different measurement tasks, then adaptability is improved, but structural complexity increases
Solution Approach 1:
The patent implements a dynamic repositioning mechanism where the optical measuring unit can be moved between different positions on the device housing (first position for monitor measurement, second position for projection surface measurement, third position for ambient light measurement) through simple mechanical means, allowing structural adaptability without excessive complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case

AI summary
A handheld colorimeter comprises a housing with a measuring unit that receives measuring light through a measuring window (15), converts it into measurement signals, processes these signals into digital color measurement data, and makes it available via a communication interface. A U-shaped bracket (B) is arranged on the housing (G), and a diffuser is integrated into its central section (9). The two side arms (7, 8) of the bracket are rotatably mounted on the housing so that the bracket (B) can be pivoted 180° from a monitor position to an ambient light position and back to the monitor position. In the ambient light position, the diffuser (11) is located in front of the measuring window (15), while in the monitor position, it is located on one of the rear walls (2) of the housing (G) opposite the front wall (1). Retaining elements are provided on the housing (G) and on the two side arms (7, 8) of the bracket (B) to hold the bracket (B) in its monitor and ambient light positions, respectively.The handheld colorimeter has a simple design and is especially suitable for monitor, projection surface and ambient light measurements.
