Paper Drilling Positioning Device for Drawer Handle Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional plastic drilling positioning plates are environmentally unfriendly and lack flexibility in hole position adjustment, limiting their adaptability to various drawer sizes and configurations.
Innovation Solution
A drilling positioning device made of paper with a main body featuring parallel bores rows and a center line aligned with the drawer's mark line, allowing for accurate drilling and easy adjustment of hole positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a plastic drilling positioning plate is used, then the drilling operation can be guided with preset bore positions, but it causes adverse effects on the environment including resource waste and disposal issues
Solution Approach 1:
The patent changes the material parameter from plastic to paper, transforming the drilling positioning device from an environmentally harmful material to an eco-friendly alternative. The paper-based device maintains the essential functional parameters (preset bore positions, center line alignment) while eliminating the environmental pollution and resource waste associated with plastic materials.
2Measurement precision
If the hole positions are preset on the drilling positioning plate, then drilling can be guided accurately, but the flexibility and adaptability for size and configuration alterations are limited
Solution Approach 1:
The patent introduces a movable scale component that can be adjusted along the center line of the paper drilling positioning device. This dynamic element allows the preset hole positions to be modified according to different drawer sizes and configurations, while the paper base maintains accurate positioning through its printed center line and scale markings. The combination enables both precision and adaptability.

AI summary
A drilling positioning device includes a main body, a handgrip part, and a center line. The main body has a first side and a second side disposed in a parallel arrangement along a first direction, and a first bores row and a second bores row disposed in a parallel arrangement at intervals along a second direction perpendicular to the first direction. The handgrip part is pivotally disposed on the first side and includes an observation hole. The center line extends along the second direction from the handgrip part toward the second side between the first bores row and the second bores row and is arranged in parallel thereto. The center line is aligned with a mark line on a drawer, so that drilling marks are drawn through the first and second bores rows, allowing the fastening bores to be drilled at predetermined positions.
