Solution Overview

Problem

Conventional measuring tape devices suffer from an anti-slip piece that easily comes apart from the pulling piece, leading to durability issues and excessive adhesive use during production.

Innovation Solution

The hook plate features a pulling part with three slightly extruded edges surrounding a primary surface, preventing the anti-slip piece from detaching, and includes magnetic pieces for enhanced grip on objects, reducing adhesive spillage and improving measurement convenience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the anti-slip piece is directly adhered onto the flat surface of the pulling piece, then the production process is simple, but the anti-slip piece easily comes apart and adhesive spills excessively

Engineering Contradiction:
Improveproduction process simplicityVSAvoidanti-slip piece attachment durability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent introduces a third dimension by creating an extruded edge structure that rises from the flat surface. This extruded edge forms a boundary that confines the adhesive within a specific area, preventing it from spreading excessively while also providing a physical barrier that secures the anti-slip piece in place. The extruded edge essentially adds a vertical dimension to the originally flat surface, creating a three-dimensional structure that solves both the adhesive spillage and attachment durability issues.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If adhesive is spread extensively on the flat surface to ensure anti-slip piece attachment, then the anti-slip piece is securely attached, but excessive adhesive material is wasted

Engineering Contradiction:
Improveanti-slip piece attachment strengthVSAvoidadhesive material waste
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The extruded edge creates a localized adhesive application area by forming a boundary around the region where adhesive should be applied. Instead of spreading adhesive across the entire flat surface, the adhesive is confined to the specific area enclosed by the extruded edge. This localized approach ensures that the adhesive is applied only where needed for securing the anti-slip piece, preventing both insufficient attachment and excessive material waste.

Inventive Principle:
Principle #3Local quality

3Ease of manufacture

If the pulling piece has a flat surface design, then the manufacturing is simple, but the anti-slip piece easily detaches during extensive use

Engineering Contradiction:
Improvepulling piece manufacturing simplicityVSAvoidhook plate usage durability
Core Design Contradiction:
Ease of manufactureVSDuration of action of stationary object

Solution Approach 1:

The patent transforms the flat two-dimensional surface into a three-dimensional structure by extruding edges that rise vertically from the surface. This addition of vertical dimension creates physical boundaries that prevent the anti-slip piece from detaching during use. The extruded edges form a retaining structure that mechanically secures the anti-slip piece, significantly improving attachment durability while maintaining manufacturing simplicity through a single extrusion process.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

A measuring tape device has a hook piece. The hook piece is used for preventing the tape from slipping off from an object of measure. The hook piece consists of a hook body and an anti-slip piece; the hook body consists of a pulling part and a connecting part; the pulling part is a flat surface, the connecting part extends out from one side of the pulling part in the direction that is perpendicular to the pulling part; the anti-slip piece is adhered onto the inside surface of the pulling part; and magnetic pieces are attached to the outside surface of the pulling part. Therefore, during the measuring process, both the anti-slip piece and the magnetic pieces may help keeping the hook plate of the measuring tape attaching to the object of measure and hence the tape does not slip off from the object of measure easily.
