Transparent Stamp Handle Housing for Secure Custom Figure Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stamp handles have a monotonous appearance, lack customization options, and are prone to deformation of the transparent plate, leading to easy detachment and inadequate protection of the figure.
Innovation Solution
A stamp handle design featuring a handle main body with a transparent housing that includes a top cover wall and an annular cover wall, with engaging and clamping portions for secure attachment, providing a larger area for customization and protection against deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional stamp handle uses a small figure-installed portion, then the structure is simple, but the customization options are limited and the appearance is monotonous
Solution Approach 1:
The transparent housing is nested within the handle main body, with the assembling chamber positioned inside the handle cavity. This nesting arrangement allows the figure-installed portion to be integrated within the handle structure while maintaining a compact overall form, thereby enabling customization without significantly increasing external complexity
Solution Approach 2:
The handle is segmented into distinct functional portions: the handle main body, the transparent housing, and the figure-installed portion within the assembling chamber. This segmentation allows each component to be independently designed and customized, with the figure area separated from the structural elements, enabling greater design flexibility
2Strength
If a conventional stamp handle uses a flat or U-shaped transparent plate attached only by lateral-side protrusions, then the structure is simple, but the transparent plate is prone to bending and deformation under applied force
Solution Approach 1:
The transparent housing employs curved surfaces including the arc-shaped first side wall and the rounded corners of the base wall. These curved geometries provide structural reinforcement that resists bending forces better than flat plates, while the arch-like configuration of the cover wall distributes applied loads more effectively across the structure
Solution Approach 2:
The housing structure combines the transparent plate material with the handle main body material to form a composite assembly. The integration of the transparent housing with the opaque handle main body creates a structurally superior assembly where the two materials work together to resist deformation, with the handle main body providing additional support beyond what the transparent plate alone could provide
3Reliability
If a conventional stamp handle uses a transparent plate attached only by lateral-side protrusions, then the manufacturing process is simple, but the transparent plate detaches easily and cannot provide proper protection
Solution Approach 1:
The attachment mechanism is segmented into multiple independent engagement features: the first protrusion engaging with the first recess, the second protrusion engaging with the second recess, and the third protrusion engaging with the third recess. This segmentation of the attachment system distributes the attachment forces across multiple points, significantly improving reliability while each individual engagement feature remains simple to manufacture
Solution Approach 2:
Different regions of the housing are provided with different local qualities: the base wall has a third protrusion for rear attachment, the first side wall has a second protrusion for lateral attachment, and the cover wall has a first protrusion for front attachment. Each local region is optimized with specific engagement features appropriate to its position and functional requirements, ensuring reliable attachment throughout the structure

AI summary
A stamp handle mounted on a stamp seat of a stamp comprises a handle main body and a transparent housing. The handle main body comprises a top board portion and an exterior wall extending downwardly from the top board portion. The transparent housing comprises a top cover wall and an annular cover wall extending downwardly from the top cover wall, so is unlikely to deform. The transparent housing is detachably mounted outside of the handle main body. The top board portion and the exterior wall are revealed through the transparent housing, thereby enlarging an area for setting figures, improving variabilities of the stamp. The transparent housing is unlikely to deform. The transparent housing is mounted on the handle main body through at least one engaging portion and clamping portion, thereby securely mounted on the handle main body to protect the figure on the handle main body.
