Wristwatch Pointer Thick Section for Luminous Member Volume
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wristwatch pointers with luminous members have insufficient light-emitting luminance and short light-emitting times due to the limited thickness and volume of the luminous member, which is the same as the pointer body thickness.
Innovation Solution
A pointer design featuring thick sections with accommodation sections that penetrate through the front and back surfaces, allowing for a larger volume luminous member to be embedded, increasing luminance and extending light-emitting time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the luminous member is made with the same thickness as the pointer body, then the pointer structure remains simple, but the light-emitting luminance and light-emitting time are insufficient
Solution Approach 1:
The invention introduces a thick section that protrudes from the pointer body in the thickness direction, creating a third-dimensional structure. This allows the luminous member to be positioned in a protruding portion with greater thickness, increasing its volume and light-emitting capacity without expanding the planar dimensions of the pointer. The accommodation section is formed within this thick section to house the enlarged luminous member.
2Duration of action of moving object
If the luminous member thickness is increased to improve light-emitting time, then the light-emitting duration extends, but the pointer body thickness must be increased accordingly
Solution Approach 1:
The pointer body is segmented into a base portion and a thick section that protrudes from it. The luminous member is specifically positioned in the thick section, separating the luminous function from the main pointer body. This segmentation allows the luminous member to have increased thickness for longer light-emitting duration without increasing the overall thickness of the pointer body, as the thick section is a localized addition.
3Quantity of substance
If a larger volume luminous member is provided to increase luminance, then the light-emitting luminance improves, but the pointer structure becomes more complex
Solution Approach 1:
The luminous member is nested within the thick section, which itself is part of the pointer body structure. The accommodation section is formed within the thick section to house the luminous member. This nested arrangement allows the luminous member to have increased volume without requiring a proportionally increased overall pointer structure, as the luminous member is contained within the existing thick section framework.
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 enhanced design provides higher luminance and longer light-emitting times for the luminous member, ensuring better visibility in dark environments without increasing the pointer's weight or altering its balance.
Implementation Method 1
a luminous member (15) provided in the accommodation section (14)... light emitted by the luminous member (15) in a dark place is released upward through the metal thin film
