Input Assembly Fingerprint Module Nesting in Touch Panel Blind Hole
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing terminal manufacturing methods lack efficient integration of fingerprint identification technology with display screen components and touch panels, leading to increased production costs and potential damage to touch panels from unauthorized use.
Innovation Solution
A method for manufacturing an input assembly that includes a touch panel with a blind hole, a decoration enclosure for the fingerprint chip package structure, and a display screen component, where the fingerprint chip package structure is mounted in the decoration enclosure and assembled within the blind hole, enhancing assembly efficiency and reducing costs by ensuring precise orthographic projections for secure fingerprint identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the fingerprint chip package structure is separately assembled and then integrated with the touch panel and display screen component, then the assembly process becomes complex and time-consuming, but integrating all components together from the beginning would increase the risk of damage to the touch panel and make manufacturing more difficult
Solution Approach 1:
The fingerprint chip package structure is nested within a decoration enclosure that has a cavity specifically designed to accommodate it. This nested arrangement allows the fingerprint module to be pre-assembled and protected within the decoration enclosure before being integrated with the touch panel and display screen component, thereby improving assembly efficiency while managing complexity through hierarchical organization of components
2Reliability
If the fingerprint chip package structure is mounted separately and then integrated with the touch panel, then the touch panel may be damaged during unauthorized use or handling, but providing additional protective structures would increase device complexity and manufacturing difficulty
Solution Approach 1:
The decoration enclosure serves multiple functions simultaneously: it acts as a protective housing for the fingerprint chip package structure, provides aesthetic decoration, and integrates with the touch panel and display screen component mounting structure. By merging these functions into a single component, the patent achieves protection without significantly increasing device complexity
3Ease of manufacture
If traditional separate mounting methods are used for fingerprint chip, touch panel, and display screen component, then production costs increase and assembly time is extended, but integrating them together would make manufacturing and repair more difficult
Solution Approach 1:
While the components are integrated in appearance, the design maintains functional segmentation where the fingerprint chip package structure, touch panel, and display screen component can be independently replaced. The decoration enclosure with its cavity structure allows the fingerprint module to be accessed and replaced separately, preserving ease of repair despite the integrated aesthetic design

AI summary
A method for manufacturing an input assembly, an input assembly and a terminal are provided. The input assembly includes a decoration enclosure, a touch panel, a fingerprint chip package structure and a display screen component, and the touch panel defines a blind hole in a surface thereof. The method for manufacturing the input assembly includes: mounting the fingerprint chip package structure in the decoration enclosure; mounting the decoration enclosure carried with the fingerprint chip package structure in the blind hole; mounting the display screen component to the surface of the touch panel, in which a first orthographic projection of the display screen component in the surface of the touch panel overlaps a second orthographic projection of the decoration enclosure in the surface of the touch panel.
