Unified LED Casing with Anchoring Cradle for Color Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing LED units for industrial machine control require separate casings and molds, increasing manufacturing and management costs, and lack an efficient method for identifying the color of the LED light during assembly, leading to potential errors and complexity.
Innovation Solution
A unified casing design for both LED and contact units, featuring an anchoring cradle made of plastic matching the LED light color, which provides immediate color indication and eliminates the need for additional color signs, allowing a single mold for both types and simplifying assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate casings are used for LED units and contact units, then the LED diode can be properly housed and protected, but the manufacturing cost increases due to requiring two different molds
Solution Approach 1:
The patent applies universality by designing a single casing structure that can accommodate both LED units and contact units. The casing includes a receiving space with a fixing component that can securely hold either an LED circuit board or a contact unit, eliminating the need for separate casing designs for each component type.
Solution Approach 2:
The patent applies segmentation by making the fixing component detachable and replaceable. The LED circuit board or contact unit can be independently removed and replaced within the same casing, allowing flexible configuration and simplifying manufacturing by using a single mold for the casing.
2Loss of information
If a colored sign is added to the casing to indicate LED color, then color identification is provided, but the assembly complexity increases and color matching errors may occur
Solution Approach 1:
The patent applies color changes by making the fixing component itself colored to match the LED diode color. The fixing component is provided in different colors (red, yellow, green, blue) corresponding to different LED diode colors, allowing direct visual identification without additional signs or labels.
Solution Approach 2:
The patent merges the color identification function with the structural fixing component. The fixing component serves dual purposes: mechanically securing the LED circuit board or contact unit and providing color identification through its own coloration, eliminating the need for separate identification elements.
3Stability of the object's composition
If the LED circuit board is firmly fixed in the casing, then stability is improved, but the ability to replace or upgrade the LED unit is reduced
Solution Approach 1:
The patent applies dynamics by designing a removable and replaceable fixing component. The fixing component can be easily detached and reattached, allowing the LED circuit board to be firmly secured during operation while enabling simple replacement or upgrade when needed. The fixing component itself can be replaced with different types or colors as required.
