Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tape measures lack a robust lighting system capable of functioning as a flashlight and provide adequate protection for internal components, while maintaining a compact design.
Innovation Solution
A tape measure with an integrated lighting system that includes a circuit board, light source, and optical component, housed in a recessed frame with impact-absorbing materials, and a wire retention system to secure components and prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a lighting system is integrated into the tape measure, then the tape measure can function as a flashlight and illuminate the tape blade, but the device complexity increases
Solution Approach 1:
The patent combines a lighting system (LED, circuit board, optical component) with the traditional tape measure components (housing, reel, blade) to create a multi-functional device that serves both as a measuring tool and a flashlight, eliminating the need for separate tools
Solution Approach 2:
The tape measure housing is designed to accommodate multiple functions: measurement (blade extension), illumination (lighting system directed forward), and flashlight operation (light directed through optical component), making the device universally applicable in various work conditions
2Reliability
If a recessed frame with impact-absorbing materials is used to protect internal components, then the protection against impact is improved, but the volume of the housing increases
Solution Approach 1:
The patent incorporates impact-absorbing materials and recessed frames around the lighting system and other internal components before any impact occurs, providing pre-positioned protection that absorbs shock and prevents damage to sensitive elements
Solution Approach 2:
The lighting system components (circuit board, LED, optical component) are nested within a recessed frame structure that is itself nested within the housing, creating layered protection without requiring a significantly larger outer housing volume
3Reliability
If a wire retention system is implemented to secure wires, then the reliability of electrical connections is improved, but the device complexity increases
Solution Approach 1:
The wire retention system uses the housing structure itself to secure wires through integrated channels and retention features, eliminating the need for separate wire management components and allowing the housing to serve dual purposes of structural support and wire organization
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The tape measure functions as a flashlight and illuminates the tape blade, while providing robust protection against impact and maintaining a compact form factor, with a charging system that indicates battery status.
Implementation Method 1
a light-emitting diode, an optical component, and a holder. The optical component at least partially surrounds the light-emitting diode
Implementation Method 2
a spring coupled to the reel. The extension of the elongate tape causes rotation of the reel which tensions the spring storing energy within the spring and the spring releases energy driving the reel to retract and wind the elongate tape on the reel
Data Source
AI summary
A tool such as a tape measure, including a lighting system is shown. The lighting system includes a light source configured to direct light forward and strong enough to act as a flashlight. The tape measure further includes a housing designed to be compact and rugged enough to protect the internal components related to the lighting system from coming loose or suffering damage due to an impact or vibrations.
