Solution Overview

Problem

Conventional fastening methods, such as screws, fail to firmly fix objects in place after assembly, making it difficult to repeatedly couple and separate objects quickly.

Innovation Solution

A structure and method for retaining fastening element solder, featuring a fastening element with a solderable surface and a retaining portion that solidifies solder during the soldering process, allowing for precise positioning and secure coupling and separation of objects through a fastening or hole portion, enabling repeated assembly and disassembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional fastening methods (screws) are used to couple objects, then the objects can be coupled together, but the objects are not firmly fixed in place and cannot be repeatedly coupled and separated quickly

Engineering Contradiction:
Improvefirm fixationVSAvoidassembly efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The invention divides the fastening element into distinct functional portions: a solderable surface for permanent attachment to the first object, a retaining portion for securing solder, and a fastening portion for removable coupling with the second object. This segmentation allows each portion to perform its specific function optimally, achieving both firm fixation and assembly efficiency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention combines multiple fastening mechanisms into a single integrated fastening element: soldering provides permanent attachment to the first object, while the fastening portion enables removable coupling with the second object. This merging allows the system to achieve both firm fixation through solder and quick assembly/disassembly through the fastening portion.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If solder is used to firmly attach the fastening element to the first object, then firm coupling is achieved, but the solder may flow into the fastening portion and solidify, causing interference with the second object

Engineering Contradiction:
Improvefirm couplingVSAvoidsolder interference
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The invention extracts the harmful effect by providing a dedicated retaining portion that captures and contains the solder, preventing it from flowing into the fastening portion. The retaining portion acts as a separate compartment that isolates the solder from the fastening functionality, eliminating the interference problem.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The retaining portion serves as an intermediary structure between the solderable surface and the fastening portion. It mediates the solder flow by providing a designated path and containment area, preventing the solder from directly entering the fastening portion and causing interference with the second object.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If the fastening element allows repeated coupling and separation, then assembly efficiency is improved, but the firm fixation is compromised

Engineering Contradiction:
Improveassembly efficiencyVSAvoidfirm fixation
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The fastening element is segmented into a solderable surface for permanent firm fixation to the first object and a fastening portion for removable coupling with the second object. This segmentation allows the system to simultaneously achieve firm fixation through solder and repeated assembly/disassembly through the fastening portion without compromising either function.

Inventive Principle:
Principle #1Segmentation

AI summary

A structure and method for retaining fastening element solder are introduced. The structure includes a fastening element which has a solderable surface and a fastening portion or a hole portion. One end of the hole portion or the fastening portion has a retaining portion. During a soldering heating process, solder flows into or enters the retaining portion to cool down and solidify. The solidified solder is retained in the retaining portion. The fastening element is firmly coupled to a first object because of coordination between the solderable surface and the retaining portion, and the second object is coupled to or removed from the fastening element because of coordination between the fastening portion and the hole portion, so as to couple together and separate the first and second objects repeatedly and quickly.
