Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collision warning systems for vehicles are difficult to mount and operate effectively, especially in dynamic environments like construction sites, where ease of installation and reliable operation are crucial to prevent accidents.
Innovation Solution
A collision warning apparatus comprising a GNSS receiver, radio transceiver, and operator information unit, with analog and digital circuitry separated into roof and cabin mount units connected by a digital transmission line, allowing for easy mounting and reducing interference and shielding requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If all circuitry is integrated in a single fixed mounting unit, then device complexity is reduced, but ease of installation and adaptability to different vehicle configurations deteriorates
Solution Approach 1:
The collision warning apparatus is divided into separate mounting units (roof mount unit and cabin mount unit) that can be independently installed and configured. This segmentation allows each unit to be optimized for its specific location and function, improving ease of installation and adaptability to different vehicle configurations while maintaining manageable system complexity through modular design
2Reliability
If analog transmission line is used between mounting units, then signal transmission is achieved, but signal damping and interference increase requiring extended shielding
Solution Approach 1:
The patent replaces analog signal transmission with digital signal transmission between the mounting units. Digital signals are more resistant to damping and interference, eliminating the need for extended shielding and improving signal transmission quality and reliability in challenging electromagnetic environments
3Object-affected harmful factors
If thick shielded transmission lines are used, then signal interference is reduced, but ease of installation and routing through vehicle structures deteriorates
Solution Approach 1:
The patent substitutes digital transmission for analog transmission, which fundamentally changes the shielding requirements. Digital signals can be transmitted through thinner, less intrusive cabling that is easier to route through vehicle structures such as window slits, while maintaining immunity to interference through the digital signal format itself

AI summary
A collision warning apparatus, to be mounted to a vehicle, has a roof mount unit (40), to be fixed to the vehicle's roof, as well as a cabin mount unit (41) to be located in the driver's cabin. A digital transmission line (42) is provided for connecting the two. The roof mount unit (40) houses the antennas as well as the analog circuitry of the apparatus, while the cabin mount unit (41) comprises a display (26). The data sent through the transmission line (42) is digital, which allows to make the transmission line thin and flexible. The roof mount unit (40) has a magnet (43) and batteries (48) mounted in its base section (46), with the lighter components, in particular the antennas (30a, 31a, 32a) located in its head section (47).
