Solution Overview
Problem
Conventional presentation and exhibition stand systems require complex electrical wiring, limiting flexibility in arranging electrical devices and increasing the time and effort required for design and redesign, especially in shop window displays that need frequent updates outside regular hours.
Innovation Solution
A current-carrying wall member with alternately arranged electrical conductor tracks of different polarities on its front side and terminal contacts on the back side, combined with a current collector featuring multiple contact needles that can be magnetically attached, allowing for flexible and efficient power supply to electrical devices without the need for extensive wiring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional electrical wiring is used to supply power to electrical devices in presentation stands, then reliable power supply is achieved, but flexibility in arranging electrical devices is greatly limited and assembly time increases
Solution Approach 1:
The wall member is segmented into multiple independent conductor tracks (first polarity and second polarity) that are spatially separated and alternately arranged. This segmentation allows electrical devices to be connected at any position along the tracks without requiring complex wiring, as each track independently carries power to different locations.
Solution Approach 2:
The conductor tracks are arranged in an alternating pattern across the wall member surface, utilizing two-dimensional spatial distribution rather than traditional linear wiring. This dimensional arrangement enables flexible positioning of electrical devices at multiple locations simultaneously without increasing wiring complexity.
2Productivity
If conventional electrical wiring is used for power supply, then stable power connection is ensured, but time and effort for design and redesign increases
Solution Approach 1:
The conductor tracks are pre-installed and integrated into the wall member structure during manufacturing. This preliminary action eliminates the need for on-site wiring during assembly, allowing electrical devices to be quickly connected by simply attaching them to the pre-positioned tracks, thereby significantly reducing assembly and redesign time.
3Adaptability or versatility
If alternately arranged conductor tracks of different polarities are provided on the front side, then flexible positioning and rotation of electrical devices is enabled, but manufacturing complexity increases
Solution Approach 1:
Different regions of the wall member front side are assigned different conductor track polarities in an alternating pattern. This local quality differentiation enables electrical devices to be positioned and rotated flexibly, as they can connect to adjacent tracks of opposite polarity regardless of their orientation, while the manufacturing process remains standardized.
4Ease of operation
If terminal contacts are arranged on the back side connected to conductor tracks, then electrical connection is simplified, but space utilization is reduced
Solution Approach 1:
Instead of placing terminal contacts on the front side where they would interfere with device positioning, the terminal contacts are inverted to the back side of the wall member. This inversion maintains electrical connectivity through the conductor tracks while preserving the entire front surface area for flexible device arrangement and rotation.
