Solution Overview

Problem

Conventional stamp assembly is inconvenient due to manual assembly of the moving seat, leading to unequal forces and potential skewing of components, requiring frequent readjustments.

Innovation Solution

A covering assembly with a top cover and bottom cover that transfers pointed forces into planar forces, increasing contact area and assembly convenience, and includes features like retaining members, guiding surfaces, and slip-proof portions to facilitate uniform force application and stability during assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual assembly is used without covering assembly, then the assembly process is simple, but the force application is uneven causing components to skew and requiring frequent readjustments

Engineering Contradiction:

Improveassembly convenienceVSAvoidpositioning accuracy

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The covering assembly acts as an intermediary tool between the user's hands and the components being assembled. It provides a structured interface with guiding surfaces and retaining members that mediate the assembly process, ensuring proper alignment and force distribution while maintaining operational simplicity

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The covering assembly is divided into functional segments including the top cover with retaining member, bottom cover with guiding surface, and force distribution elements. Each segment performs a specific function in the assembly process, allowing for precise control of component positioning while keeping the overall device relatively simple

Inventive Principle:

Principle #1Segmentation

2Manufacturing precision

If covering assembly is used to improve force distribution, then positioning accuracy improves, but device complexity increases

Engineering Contradiction:

Improvepositioning accuracyVSAvoidassembly structure complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The covering assembly serves multiple functions simultaneously: it provides force distribution through its structural design, guides component alignment via guiding surfaces, retains components in proper position with retaining members, and protects the ink pad. This multi-functionality reduces the need for separate specialized tools or complex assembly mechanisms

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

Instead of designing complex alignment mechanisms to force components into place, the invention inverts the approach by having the covering assembly's structural features (guiding surfaces, retaining members) naturally guide and constrain the components during assembly, allowing precision to emerge from the tool's geometry rather than complex active control mechanisms

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

A covering assembly is disposed on an inked printing assembly of a stamp. The covering assembly has a top cover and a bottom cover. The top cover is detachably disposed above the inked printing assembly. The bottom cover is detachably disposed below the inked printing assembly, is located below the top cover at a spaced interval, and has a bottom wall. The covering assembly can assist in assembling the inked printing assembly. The disposition of the top cover and the bottom cover can transfer pointed force into planar force for increasing a contact area, the forcing uniformity, and the assembly convenience.
