Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The labor-intensive process of connecting multiple electrically powered devices to a power source in retail display systems, which requires custom wiring and extensive routing of wires, is inefficient and prone to errors due to the lack of a standardized power distribution and mounting system.
Innovation Solution
A modular electrical power distribution and mounting system featuring a mounting wall with apertures and power delivery contacts on the rear side, where electrically powered devices with complementary mounting pins and contacts can be easily and securely inserted, ensuring stable mounting and electrical connection without manual contact with live wires, using a combination of shaft and head configurations for secure retention and spring mechanisms for continuous engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If custom wiring and individual hand-made connections are used for each device, then each device can be connected to power, but the installation process becomes labor-intensive and time-consuming
Solution Approach 1:
The system divides the power distribution function into modular power delivery members, each serving specific aperture locations. Instead of running individual wires to each device, the wall itself is segmented into functional units with integrated power delivery capabilities at predetermined locations.
Solution Approach 2:
Power delivery members are pre-installed in the wall during construction, with electrical connections already established at each aperture location. This preliminary action eliminates the need for on-site wiring and connection work during device installation.
2Ease of operation
If power delivery contacts are accessible through apertures for easy connection, then device installation is simplified, but electrical shock hazards increase
Solution Approach 1:
The aperture acts as an intermediary mechanism that guides the mounting pin into proper alignment with the power delivery contacts. The pin serves as a mediator that makes electrical contact automatically during the mechanical mounting process, eliminating the need for manual contact with live wires.
Solution Approach 2:
The system enables self-service installation where the device's own mounting pins automatically establish electrical connections with the power delivery contacts during the mechanical mounting process. The installation act itself performs both the mechanical mounting and electrical connection functions simultaneously.
3Productivity
If a standardized aperture pattern is used in the wall, then modular device installation is enabled, but flexibility in device placement is reduced
Solution Approach 1:
The standardized aperture pattern creates universal mounting locations that can accommodate various device types. Each aperture is designed to work with complementary mounting pins, allowing different devices with appropriate pin configurations to be installed at the same locations.
Solution Approach 2:
The system allows for variations in the aperture pattern configuration to be implemented based on specific installation requirements. Different wall designs can use different aperture arrangements while maintaining the same fundamental power delivery mechanism.
4Stability of the object's composition
If mounting pins with shaft and head configurations are used, then secure retention against lateral and axial movement is achieved, but the complexity of the mounting components increases
Solution Approach 1:
The mounting pin uses an asymmetric head-shaft configuration where the head portion is enlarged relative to the shaft. This asymmetric design provides lateral retention through the head's geometry while the shaft provides axial engagement, achieving stable mounting without complex multi-component assemblies.
