Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If multiple circuit board segments are connected to achieve long lamp strip length, then the lamp strip length is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent divides the lamp strip into modular segments, each containing a circuit board with LED components and connection terminals. These segments can be connected in series to achieve desired lengths, with each segment being independently manufacturable and testable before final assembly.
Solution Approach 2:
The patent introduces connection terminals as intermediary components between circuit board segments. These terminals facilitate reliable electrical and mechanical connections between segments, simplifying the assembly process and ensuring consistent performance across multi-segment configurations.
2Reliability
If high temperature soldering is used to connect LED patch lamp beads to wires, then the electrical connection is improved, but thermal damage occurs causing false soldering and poor contact
Solution Approach 1:
The patent introduces a heat-resistant insulating layer as an intermediary between the wire and LED patch lamp bead. This insulating layer acts as a thermal barrier during soldering, protecting the LED components from excessive heat while allowing reliable electrical connections to be formed through controlled soldering processes.
Solution Approach 2:
The patent modifies the soldering process parameters by controlling temperature and time to minimize thermal exposure of LED components. The heat-resistant insulating layer enables this by allowing higher soldering temperatures for the wire connections without directly exposing the LED beads to excessive heat.
