Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Watches worn around the neck during high-acceleration activities like rally sports risk detaching due to gravitational forces, posing safety hazards by distracting drivers and causing accidents.
Innovation Solution
A neck-worn watch design featuring a lanyard with an adjustable loop size, secured by a frictional adjusting element and stopper, ensuring the watch remains attached during intense acceleration, with a connecting element integrated into the watch housing for secure attachment and easy handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lanyard loop size is made large to allow easy passage over the head, then the ease of operation is improved, but the reliability deteriorates because the watch can detach during high-acceleration events
Solution Approach 1:
The lanyard system employs a dynamic loop size that can be adjusted between two states: a large initial loop size for easy passage over the head, and a reduced loop size for secure attachment during high-acceleration events. The adjusting element enables the user to transition between these states based on operational requirements.
Solution Approach 2:
The adjusting element is positioned to enable preliminary reduction of the loop size after the lanyard has been passed over the head. This preliminary action of reducing the loop size prepares the system for secure attachment before high-acceleration events occur, preventing detachment in advance.
2Reliability
If the lanyard loop size is reduced to prevent detachment, then the reliability is improved, but the ease of operation deteriorates because it becomes difficult to pass over the head
Solution Approach 1:
The lanyard system employs a dynamic loop size that can be adjusted between two states: a large initial loop size for easy passage over the head, and a reduced loop size for secure attachment during high-acceleration events. The adjusting element enables the user to transition between these states based on operational requirements.
Solution Approach 2:
The lanyard system segments the loop size into two distinct functional states: a large initial state for donning and a reduced state for secure wear. The adjusting element acts as a segmentation mechanism that divides the single lanyard structure into functionally distinct configurations.
3Reliability
If the watch is secured tightly to prevent detachment, then the reliability is improved, but the comfort deteriorates due to restriction of movement and breathing
Solution Approach 1:
The lanyard system employs a dynamic loop size that can be adjusted between two states: a large initial loop size for easy passage over the head, and a reduced loop size for secure attachment during high-acceleration events. The adjusting element enables the user to transition between these states based on operational requirements.
Solution Approach 2:
The adjusting element creates a local reduction in loop size at the critical attachment point (chin area) while maintaining a larger overall loop configuration. This localized quality change ensures security where needed without globally restricting movement and breathing.
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 adjustable lanyard system prevents the watch from detaching, maintaining safe time measurement during high-acceleration events, enhancing driving safety by keeping the watch securely in place on the wearer's chin, reducing the risk of accidents.
Implementation Method 1
a loop size of the lanyard engaging around the neck can be variably adjusted by means of an adjusting element engaging the lanyard

AI summary
A watch for time measurement is provided with a watch housing for housing a time measuring unit, a connecting element attached to the watch case, and a lanyard connected to the connecting element for wearing around a neck of a person. A loop size of the lanyard engaging around the neck can be variably adjusted with the aid of an adjusting element engaging on the lanyard. The setting element allows the watch to be held back in a loss-proof manner with a reduced loop size of the lanyard, so that time measurement in a motor vehicle, especially in rally sport, is possible with good driving safety.
