Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gas detector tubes with printed concentration demarcations on the tube surface interfere with optical reading by electronic devices and lack versatility for visual and electronic reading, leading to inaccurate and obstructed views of the length-of-stain for target gas concentration determination.
Innovation Solution
A gas detector tube template with scale cards that can be reversibly inserted into pockets, allowing for accurate and flexible reading of gas detector tubes without printed demarcations on the tube, enabling both visual and electronic measurement of gas concentrations using optical imaging technology.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If concentration demarcations are printed on the tube surface, then visual reading is facilitated, but optical reading by electronic devices is interfered with and the view of length-of-stain is obstructed
Solution Approach 1:
The scale is segmented from the tube structure and placed on a separate card that can be positioned behind the tube. This allows the scale to be visually aligned with the tube for easy reading while being optically separated to avoid obstructing the view of the length-of-stain for electronic devices.
Solution Approach 2:
A card serving as an intermediary carrier is introduced between the electronic device and the tube. The card displays the scale demarcations while being positioned such that it does not block the optical path to the tube, thus mediating between visual reading needs and electronic reading requirements.
2Adaptability or versatility
If scale cards are reversibly inserted into pockets on the template, then versatility for different gas concentrations is improved, but device complexity increases
Solution Approach 1:
The template is designed with multiple pockets that can accommodate different scale cards for various gas concentrations and types. This universal design allows a single template structure to serve multiple functions by simply changing the scale cards, rather than requiring different templates for each gas type.
Solution Approach 2:
The scale cards are designed to be reversibly inserted and removed from the pockets, creating a dynamic configuration. This allows the user to adapt the template to different measurement needs by swapping scale cards, providing flexibility without permanently complicating the base structure.

AI summary
Gas detector tube templates are described. Gas detector tubes may be used to determine the concentration of target gases in a sampled gas either visually or electronically. Gas detector tubes for visual reading have the length-of-stain demarcations printed or etched on the transparent tube. However, the demarcations may interfere with electronic reading of gas detector tubes. Embodiments of a gas detector tube template may be used to accurately and reliably read gas detector tubes that do not have concentration demarcations printed on the tube in the working area adjacent to the chemical reagent. The gas detector tube template may have a gas detector tube holder capable of reversibly receiving a gas detector tube and two scale card holders. The gas detector tube template could have a left and right scale holder hingedly connected to the gas detector tube holder. The gas detector tube template may be used with scale cards capable of being, reversibly received in the scale rockets.
