Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the fusible body is simply placed in the casing without positioning structures, then the assembly process is simple, but the position of the fusible body becomes unstable and difficult to fix

Engineering Contradiction:
Improveassembly simplicityVSAvoidfusible body position stability
Core Design Contradiction:
Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The socket is divided into a receiving seat and two end seats, with the receiving seat further divided into two sides. Each side has an indentation that receives a corresponding side of the fusible body. This segmentation allows the fusible body to be positioned and fixed stably in the socket through the cooperative engagement of multiple discrete structural elements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The indentations on the receiving seat act as intermediary structures between the fusible body and the socket. These indentations receive and hold the sides of the fusible body, serving as a mediating mechanism that ensures stable positioning without requiring complex external fixing devices or specialized assembly equipment.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If the fusible body position is not fixed, then the assembly is easier, but the distance between components varies affecting the fuse's response to excessive current

Engineering Contradiction:
Improveassembly easeVSAvoidfuse response reliability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The socket is pre-configured with indentations and end seats that define specific positioning locations for the fusible body before assembly. This preliminary structural preparation ensures that when the fusible body is inserted, it automatically assumes the correct position with fixed distances to the terminals and casing wall, eliminating position variability without requiring complex assembly procedures or specialized equipment.

Inventive Principle:
Principle #10Preliminary action

3Stability of the object's composition

If positioning structures are added to fix the fusible body, then the position stability improves, but the device complexity increases

Engineering Contradiction:
Improvefusible body position stabilityVSAvoidsocket structure complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The receiving seat serves multiple functions: it provides the main receiving space for the fusible body, contains the positioning indentations on its two sides, and supports the end seats that hold the connecting parts. This multi-functionality reduces the need for separate dedicated positioning structures, thereby limiting the increase in device complexity while achieving stable fusible body positioning.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The positioning function is merged into the receiving seat structure itself through the integration of indentations on its two sides. Rather than adding separate positioning components, the receiving seat combines the functions of support and positioning, reducing overall structural complexity while ensuring stable fusible body location.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

An easy-to-assemble fuse has a fusible body, a socket, and a cover. The fusible body is engaged with the socket. The cover is covered on the socket and the fusible body and is engaged with the socket. By the engagement between the fusible body and the socket and the engagement between the socket and the cover, the fuse achieves the purpose of fast alignment and positioning. The fuse can be quickly assembled during the manufacturing process, thereby simplifying the manufacturing process, and reducing the production cost.
