Chongqing Jialong Sealing Components Co., Ltd. (hereinafter referred to as “Jialong Sealing”), a high-tech enterprise specializing in the research, development, and manufacturing of rubber and plastic products, has a patent portfolio that vividly reflects the trajectory of technological evolution and the shifting focus of its strategic priorities. The following is a systematic summary and analysis based on publicly available patent information:

　 　I. Total Number of Patents and Distribution by Type

　　As of July 2025, Jialong Sealing has accumulated a total of 58 valid patents, including trademarks and copyrights. Among these, utility model patents account for over 90%, design patents comprise less than 5%, and no invention patents have been publicly disclosed to date. The distribution of patent types underscores the company’s R&D focus on technological improvements and application‑driven innovation.

　　 II. Analysis of the Evolution of the Technological Field

　　1. The Basic Sealing Technology Phase (2001–2020)

　　Early patents focused on optimizing the structure of conventional rubber seals, such as composite sealing rings and dust covers, to meet the basic component‑supply needs of automotive and motorcycle OEMs. A representative patent, “A Composite Sealing Rubber Ring” (granted in 2022), enhances sealing reliability through a multi‑layer structural design.

　　2. Functional Integration and Expansion Phase (2021–2023)

　　Lightweighting of structural components: Develop metal–rubber composite parts such as hollow spherical pins and thrust rod assemblies, and employ forging processes—e.g., substituting 40Cr steel for aluminum alloy—to enhance strength and wear resistance.

　　Shock-absorption technology upgrade: The “compressor shock-absorbing rubber pad” (2023) enhances cushioning performance through an optimized groove design in its elastic layer.

　　3. The Stage of Process Intelligence and Scenario Innovation (2024–2025)

　　Process Innovation: In 2025, we will launch a “rubber‑ring flash‑removal grinding device” that features interchangeable grinding wheel diameters and automated adjustment, boosting machining efficiency by 30%. Additionally, in 2025, we will introduce a “quick‑release oil seal removal plate,” which streamlines the oil seal removal process through a plug‑in design.

　　“Waterproof Protective Cover Assembly” (2025) features a split-type corrugated tube design, tailored to meet the rapid installation requirements of automotive tailgate support struts.

 　　 III. Summary of Innovative Features

　　Strong problem orientation: 90% of the patents propose solutions to address production pain points—such as low efficiency in oil seal removal—or customer needs—such as waterproofing of automotive components.

　　Process–Material Co-Innovation: The thrust rod combines forging with high-strength steel, extending its service life by 50%; the rubber‑ring flash‑removal equipment is compatible with multiple product specifications, exhibiting pronounced flexibility in production.

　　High patent commercialization efficiency: All new patents filed in 2024–2025 were granted within one year of application, reflecting both technological maturity and practical value.

　　 IV. The Strategic Significance of Patent Portfolio Management

　　Fifty-eight patents have established a robust technological barrier, particularly in the field of intelligent manufacturing equipment, underscoring the company’s potential to drive Industry 4.0 transformation while paving the way for capitalization. These patents serve as a tangible embodiment of Jialong Sealing’s technical expertise; its leap from “application‑driven improvements” to “original breakthroughs” will determine whether the company can truly become the “Chinese benchmark” in the sealing industry—on a trajectory to achieve RMB 500 million in annual revenue within five years and go public within eight.

　　 V. Future Prospects

　　Jialong Sealing’s patent development strategy is shifting from single-component innovation to the delivery of system‑level solutions. Suggested next steps:

　　Filling the gap in invention patents: securing foundational patents for material formulations (such as high‑temperature‑resistant rubber) or core processes (such as AI‑controlled temperature forging).

　　Expanding International Patents: For the global supply chain of new-energy vehicles, prioritize the strategic deployment of sealing‑technology patents in Southeast Asia and Europe.

　　Promoting standard-setting: Transforming patented technologies such as “rapid oil seal installation” and “lightweight thrust rods” into industry standards to strengthen our influence.
