Solution Overview

Problem

Existing tape measures lack accuracy, reliability, and ease of use, leading to measurement errors, inefficiencies, and inconsistencies in construction and DIY projects.

Innovation Solution

A tape measure with a removable housing, a clip for suspension, a retractable blade with a lock mechanism, and a protrusion for square edges, along with markings for easy reading and blind measurements, enhancing precision and convenience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional tape measure design is used, then the device is simple and easy to manufacture, but measurement accuracy and reliability deteriorate due to lack of corner and base features

Engineering Contradiction:
Improvemeasurement accuracyVSAvoiddevice complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The housing is divided into a first housing portion and a second housing portion that can be removably attached together, allowing the tape measure to form different configurations (corner and base) while maintaining manufacturing simplicity. This segmentation enables the same basic components to serve multiple measurement functions without requiring a completely different device for each application.

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If traditional tape measure design is used, then the device structure is simple, but measurement consistency deteriorates due to inability to maintain proper positioning

Engineering Contradiction:
Improvemeasurement consistencyVSAvoidstructural complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The tape measure housing includes integrated corner and base features that automatically position the tape blade correctly during measurement. The right angle corners and base structures serve as self-positioning elements that guide the user into proper measurement alignment without requiring additional external tools or complex adjustment mechanisms.

Inventive Principle:
Principle #25Self-service

3Reliability

If traditional tape measure design is used, then the device is easy to operate, but measurement reliability deteriorates due to lack of positioning features

Engineering Contradiction:
Improvemeasurement reliabilityVSAvoidease of operation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The housing is pre-configured with right angle corners and base features that automatically establish proper measurement positioning before the actual measurement takes place. These features perform the preliminary action of alignment and positioning, ensuring that when measurement begins, the tape blade is already in the correct position for accurate and reliable readings.

Inventive Principle:
Principle #10Preliminary action

AI summary

Embodiments of the present disclosure may include a tape measure including a housing including a first housing portion. Embodiments may also include a second housing portion, and. In some embodiments, the first housing portion may be removably attachable to the second housing portion to form a cavity therebetween. The tape measure has a base having a pair of sharp right and left corners. The length of the base is four inches permitting the user to put the device squarely within a corner or against an edge and then add four inches to the measurement on the tape.
