Solution Overview
Problem
Existing electronic display systems for retail, such as ESLs, are typically designed as single-use housings that cannot accommodate different or repaired display devices, leading to unnecessary replacement and waste, especially when a display device fails.
Innovation Solution
A housing system comprising two plastic parts with recesses that form passages for electrical contact elements, allowing for reversible and reusable installation of electronic display devices, enabling multiple uses and easy removal without damaging the housing, and a channel system for efficient power supply through conductive tracks and terminating devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single-use housing is used to accommodate the electronic display device, then the housing can be manufactured simply and cheaply, but the housing cannot be reused after the display device fails, leading to waste and increased costs
Solution Approach 1:
The housing is divided into two separable parts (first housing part and second housing part) that can be detached from each other. This segmentation allows the display device to be removed and replaced while keeping the housing structure intact, enabling reuse of the housing after device failure or obsolescence.
Solution Approach 2:
The housing transitions from a static, permanent structure to a dynamic, reversible structure. The two housing parts can be connected and disconnected, allowing the housing to adapt between different states (assembled/disassembled) to facilitate device replacement and housing reuse.
2Reliability
If the electronic display device is permanently fixed in the housing, then the housing provides stable protection, but the entire housing must be replaced when the display device fails, increasing waste and cost
Solution Approach 1:
By separating the housing into two detachable parts, the invention enables the display device to be accessed and replaced independently without compromising the protective function of the housing structure itself.
Solution Approach 2:
The invention allows the display device to be discarded and replaced while the housing structure is recovered and reused. The detachable housing parts enable selective replacement of only the faulty component (display device) rather than the entire assembly.
3Reliability
If traditional cabling methods are used for power supply, then reliable electrical connection is achieved, but installation complexity and cabling costs increase
Solution Approach 1:
The housing structure is merged with the electrical connection system through integrated contact elements and conductive tracks. This combination eliminates the need for separate external cabling, as power and data connections are established through the housing structure itself when the two parts are connected.
Solution Approach 2:
The housing structure serves multiple functions simultaneously: mechanical protection, structural support, and electrical connection. The contact elements and conductive tracks integrated into the housing enable the housing to provide both physical enclosure and electrical pathways, reducing overall system complexity.
