Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the light-emitting body is inserted and accommodated in the casing of the fuse assembly, then the fuse state can be indicated by light, but the light-emitting body is thrown away together with the damaged fuse causing material waste and increased cost
Solution Approach 1:
The invention divides the fuse assembly into two independent parts: the fuse body (which may blow) and the light-emitting body (which remains functional). The light-emitting body is electrically connected to the fuse via conductive pieces but is not physically enclosed within the fuse casing, allowing the light-emitting body to be separated and reused when the fuse blows.
Solution Approach 2:
The light-emitting body is extracted from the fuse assembly structure, removing it from the casing that encloses the fuse. This allows the light-emitting body to be taken out and reused independently when the fuse is replaced, eliminating material waste while maintaining the indicator function.
2Reliability
If the light-emitting body is mounted within the fuse assembly, then the fuse state can be indicated by light, but the manufacturing procedure becomes more complicated and assembling cost increases
Solution Approach 1:
The invention segments the assembly process into simple steps: placing the light-emitting body on conductive pieces and inserting the fuse into the casing. This avoids complex mounting procedures while achieving the same indicator function, thereby simplifying manufacturing and reducing assembly costs.
3Reliability
If multiple fuses are used in rows, then over-current protection can be provided for multiple circuits, but checking which fuse is blown requires checking each fuse one by one causing time loss
Solution Approach 1:
The invention uses light emission (a form of optical change) from the light-emitting body to indicate the state of the fuse. When the fuse blows, the light-emitting body illuminates, providing a visual signal that allows operators to quickly identify which fuse is blown without checking each fuse individually, thereby reducing time loss while maintaining over-current protection functionality.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables cost-effective and environmentally friendly indication of fuse state through light emission, simplifying manufacturing and reducing material costs while allowing for diode recycling.
Implementation Method 1
a light-emitting body disposed between two metallic conductive pieces and in parallel to the fuse... When the fuse is blown due to an over-current, the current will flow through the light-emitting body, so that the light-emitting body illuminates to indicate the blowing of the fuse

AI summary
A fuse assembly capable of indicating whether the fuse is blown or not includes a fuse body formed therein with an accommodating space. The accommodating space is provided with two conductive terminals connected to each other via a metallic fuse. A light-emitting diode is inserted into an accommodating hole of the fuse body, thereby electrically connecting two electrodes of the light-emitting diode to the two conductive terminals. By the above arrangement, the light-emitting diode can be lighted up when the fuse body is blown.
