Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a cover frame with power contacts is used to supply power to the installation device, then the installation device can be illuminated, but the contacting becomes error-prone and requires a specially tailored carrier
Solution Approach 1:
The patent implements a standardized carrier design with uniform fastening openings that can accommodate different electronic modules (illumination modules, communication modules, charging modules) through a common interface. This universal carrier allows the same installation device structure to support multiple functional modules without requiring specially tailored carriers for each module type, thereby improving versatility while maintaining reliable power supply connections through consistent mechanical and electrical contact interfaces.
2Reliability
If electronic modules are specifically designed for particular installations, then they can be reliably connected, but they cannot be used variably for many installation devices
Solution Approach 1:
The patent divides the electronic module into separable components: a standardized carrier portion that interfaces with the installation device and a functional electronic unit that can be attached or removed. The carrier includes standardized fastening openings for mechanical connection and power supply line routing, while the electronic unit contains the specific functionality (illumination, communication, charging). This segmentation allows the same carrier to reliably connect different electronic units to various installation devices, achieving both reliability and versatility.
3Ease of operation
If power supply lines are routed through fastening openings in the carrier, then installation is simplified, but the power supply connection may become strained
Solution Approach 1:
The patent incorporates strain relief features in the power supply line routing, such as bending radii constraints and cushioning elements at the entry points through the fastening openings. The power supply lines are routed through the fastening openings with sufficient clearance and protective routing that prevents strain on the electrical connections during installation and operation. This beforehand cushioning ensures that the simplified routing through fastening openings does not compromise connection stability.
