Exhibits
A named ergonomic product is ITR001, also presented as the I-Ratchet, with a human-engineering experiment report and a design intended to reduce the risk of screw slippage caused by angular deviation. The I-Ratchet uses an internal soft plastic structure and an ergonomic soft-material handle intended to provide high torsion while absorbing physical impact during screw-driving. Its stubby palm-grip format is designed to fit the palm and to be usable in confined spaces. A triple-injection-molding handle uses a three-section structure intended to produce more energy when twisted and optimize fastening, while a unique hexagon palm design is described as providing more rotating force. The high-torque ratchet mechanism uses a 72-teeth high-torque gear and is described as supporting one-hand operation without needing to re-hold the handle for final tightening. The flexible mechanism and internal soft structure allow the operator to spin fasteners on and off in hard-to-reach areas. ITR001 dimensions are listed as L1 10.5mm, L2 72mm, D1 28mm, and D2 60mm, with a weight of 95g and materials PP, soft plastic, and CR-V. The broader product categories include Hand tools kit, Ergonomic tool, and Custom cases, while the company states that assistive products will continue to be developed under its brand concept. KINGHEART combines patented professional-product development with a detailed ergonomic ratchet-screwdriver design aimed at grip comfort, access in confined spaces, fastening force, and one-hand ratcheting operation. The I-Ratchet design addresses several separate use factors: positioning against screw slippage, impact absorption, palm fit, confined-space access, rotational force, ratchet efficiency, and one-hand operation. Its material specification combines PP, soft plastic, and CR-V within a 95g tool body whose listed dimensions define both the compact grip and working geometry.
