What are some two inventions to distinguish science and meaningful science?
You misunderstand the relationship between science and technology. If someone makes an invention which utilises particular scientific knowledge, that does not make that science any more or less meaningful. The science stands alone as valid providing it is well done and made known.
The vast majority of chemicals which are known (more than 140 million) have no applications at present. However, their discovery and reporting their properties is valid science. Some of them may be found to be useful for particular purposes in future but that does not make their discovery and characterization any more meaningful.
In many cases, insight comes not from a particular piece of scientific discovery, but by the pattern which emerges from large amounts of information, created by thousands of individual research efforts. Most of science is like this.
It is usual to distinguish between pure science and applied science, but both are equally meaningful. Pure science means finding out about some feature of the universe, not with an immediate aim, but just so that we know. Much of it has been driven by the interests and enthusiasm for finding out of individuals. In the same way that some people want to find out about literature or history by reading, others want to find out about physics, chemistry or biology by experiment and reasoning. In order to get funding (and also the motivation of some individuals) there is often a long-term aim (or more usually hope). For example, many people study the progress of cancer cells. This is not in the expectation that their results will immediately give a cure, but in the hope that increasing knowledge (adding their results to others) will give greater understanding of a complex matter, which may lead to better medical treatment.
By contrast, the testing of possible drug treatments is applied science, which typically works like this. A certain chemical group has been shown to inhibit an enzymatic process. Pure research has shown that this enzymatic process appears to be enhanced in tumor growth in some cancers. The hypothesis is therefore tested if this chemical group can slow or reverse the growth, while seeing what other effects it might have.
Similarly, metal alloys may be prepared which pure research has suggested have certain combinations of properties, and these could be advantageous in a particular application, e.g. a marine turbine to get power from the tides. This would be applied science.
Technologists and engineers use existing pure science, plus applied science in the particular area and often experiments for a particular purpose in making inventions.

Isn’t it true that science is meaningful when people adhere to it and repeat its use regularly?
The top 10 inventions from U. S. library of Congress through National Geographic are:
Printing press
Light bulb
Airplane
Personal computer
Vaccines
Automobile
Clock
Telephone
Refrigeration
Camera
To make science meaningful, we need to isolate tools that provide science to the masses of people. In my own consideration, those tools are communication tools, which would narrow down the above list to personal computer and printing press. Science could go on indefinitely, but without communication to the masses, it may never reach the stage of being meaningful. If science is published, it generally means the scientist achieved success and wants to make an announcement.
Out of the 10,000 trials it took to make a light bulb, the meaningful one is the one that worked.
