Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a dummy memory module is formed by removing memory chips without modifying the electrical circuit, then the light effect is achieved, but antenna effect and interference are induced affecting signal stability
Solution Approach 1:
The patent extracts and removes the problematic dummy memory chips from the electrical circuit path, while retaining only the necessary connecting fingers and LED components. This extraction eliminates the antenna effect source while preserving the light indication function.
Solution Approach 2:
The patent introduces an intermediary electrical circuit design that connects LEDs directly to connecting fingers without creating suspending nodes. This intermediary circuit configuration acts as a mediator that enables light emission while preventing antenna effect interference.
2Ease of operation
If LEDs are provided on the memory module, then user identification of damaged modules is enhanced, but the empty memory slot without memory module provides no light effect resulting in a dark region
Solution Approach 1:
The patent creates a copy of the light indication function by placing LEDs on the dummy memory module itself. This copying approach allows the dummy module to replicate the visual identification capability of real memory modules, providing consistent light effects whether the slot is occupied or empty.
3Use of energy by moving object
If the electrical circuit connects LEDs to connecting fingers, then power transfer and light emission are achieved, but suspending nodes or open spots are created inducing antenna effect
Solution Approach 1:
The patent changes the electrical circuit parameters by eliminating suspending nodes and open spots from the circuit path. By modifying the circuit topology to provide continuous electrical pathways, the patent maintains power transfer capability while changing the electrical characteristics to prevent antenna effect generation.

AI summary
A dummy memory board includes a substrate (10), a connecting finger (20), a plurality of light emitting diodes (30), and an electrical circuit (40). The substrate has a front surface and a back surface, and is provided with at least one dummy memory region (12). The connecting finger is close to a lower edge of the substrate for inserting into a memory slot (50). The light emitting diodes are on the substrate and close to the upper edge of the front surface and the back surface. The electrical circuit is on the substrate for connecting the light emitting diodes to the connecting finger. Thus, power from the memory slot is transferred to the light emitting diodes through the connecting finger, and the light emitting diodes are turned on to demonstrate the desired light effect. Particularly, the electrical circuit has no suspending node or open spot and interference due to antenna effect is avoided.
