Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If separate components are used for radar input/output and sensor surfaces, then functionality is maintained, but space consumption increases and assembly becomes complex
Solution Approach 1:
The patent combines the radar input/output and sensor surfaces into a single integrated combination unit that is mounted on the handle. This merging of previously separate components directly reduces the space required and simplifies assembly operations, as the combined unit is installed as one assembly rather than multiple separate components.
Solution Approach 2:
The combination unit serves multiple functions simultaneously - it contains both the radar input/output for distance and direction determination, and sensor surfaces for detecting handle operation. This multi-functionality allows the single unit to replace multiple separate components, reducing overall system complexity and space requirements.
2Ease of operation
If multiple separate components are installed in the handle, then all functions are provided, but the handle design becomes cumbersome and space is wasted
Solution Approach 1:
By merging the radar input/output and sensor surfaces into a single combination unit mounted on the handle, the patent eliminates the need for multiple separate components. This consolidation reduces the volume occupied in the handle and improves handling ease by creating a more compact, streamlined design.
3Ease of manufacture
If radar input/output and sensor surfaces are integrated in a single unit, then space is saved and assembly is simplified, but manufacturing precision requirements increase
Solution Approach 1:
The combination unit integrates radar input/output and sensor surfaces in a single assembly that is pre-configured together. This merging simplifies the overall assembly process as the unit is installed as one component, while the internal integration is handled during manufacturing of the combined unit itself.

AI summary
A locking system for vehicles comprises a lock (19) which is normally switched between a locking position and an unlocking position by means of remote control. A handle (11.1) which is arranged on a door or flap of the vehicle via a support (12.1) serves to actuate the lock. In the region of the handle (11.1) there is a locking actuator, but the latter is only effective if, by means of data communication, the authorized owner is recognized when his hand approaches the handle (11.1). There is also a radar device for determining the distance and range of an object in relation to the vehicle, the radar input and output (22.1) of which device is likewise arranged in the region of the handle (11.1). To achieve a space-saving design, according to the invention the radar input and output (22.1) and the sensor surface (21.1) of the locking actuator are combined to form a premanufactured construction unit (20.1), and therefore a combination-surface unit (23.1) then remains visible on the visible side. This unit (23.1) is arranged either in the handle (11.1) itself or in a visible region (16.1) of its support (12.1), which region is adjacent to the handle.
