Multi-industry multinational company logo design, mature, elegant, modern

K&H

K&H was founded in 2012 originally as a construction company in mainland China. 9 years later, K&H has become a multinational company with subsidiaries in technology, finance, construction, trading, property management, trading, and landscaping.
To help build a better brand image and promote digital transformation, we are looking for one single logo design suitable for all types of companies below:

K&H Investment Global
K&H Holdings
K&H Technologies
K&H Construction
K&H Education
K&H Property Management
K&H Landscaping
K&H Trading

Attached is the original logo K&H has been using in the past 10 years. Letter "K" and "H" came from the initials of two company founders, where "K" also means "science" and "H" stands for "ocean". That is why the original logo looked like a sail.

For this new logo design, we are open to ideas. We want it to be simple, modern, and elegant.
==========================================================
Very important that the design has to pass CompuMark trademark screening (check for similarity with other brands/trademarks, we will be running it throughout the contest against all submissions with 1+ stars rating)
Hint: simple combination of just the two letters won't work
