Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing haptic feedback devices have complex structures and difficult assembly processes, which reduce production efficiency.
Innovation Solution
A simplified apparatus with a base, frame, touch screen module, and a piezoelectric vibrator connected via a fixing portion, where the piezoelectric vibrator is supported by steps and partially suspended in an accommodation space on the base, and fixed to the frame using a protrusion and clip portion with screw threads for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the connecting portion is manufactured according to outlines of the base and the frame respectively, then the haptic feedback device can be assembled, but the connecting portion has a complicate structure and the assembly process is difficult
Solution Approach 1:
The patent merges the connecting portion with either the base or the frame to form an integrated structure. This eliminates the need for a separate complex connecting portion and simplifies the overall assembly process, as the vibration unit can be directly installed onto the integrated structure without additional connection components.
Solution Approach 2:
The base or frame is designed to serve multiple functions: it provides structural support, houses the vibration unit, and incorporates the connection functionality directly into its structure. This multi-functionality eliminates the need for dedicated connecting portions and reduces assembly complexity.
2Productivity
If the connecting portion has a complicate structure, then the haptic feedback device can be assembled, but the production efficiency is reduced
Solution Approach 1:
By merging the connecting portion with the base or frame, the patent reduces the number of separate components that need to be manufactured and assembled. This integration streamlines the production process, increases manufacturing efficiency, and reduces the time required for assembly operations.
Solution Approach 2:
The patent extracts the connection functionality from a separate complex connecting portion and integrates it directly into the base or frame structure. This extraction and integration eliminates unnecessary intermediate components and simplifies the overall manufacturing and assembly processes.
