[No.7] スクワット用デバイス：Pelvis-Centric Weight System [Rev.2] - Simplified

ごちゃごちゃした理屈が苦手な人向け

・シンプルへの回帰

・今回のデバイス⇔先のデバイス「No.6」（100万円以上コスト削減）

バネ方式のスクワット用デバイス

Replacing costly metal cartridges with interchangeable tension springs, this simplified Rev.2 model achieves massive cost reduction while delivering an escalating load profile (low initial force, high bottom resistance) that matches natural biomechanics.

[No.6] スクワット用デバイス：Pelvis-Centric Weight System [Rev.1] - Modular

もっとスマートにスクワットしたい人向け

・重りが邪魔な問題（No.5）をカセット式で改善

スクワット用デバイス（改良版）

[Fig. 1 Modular Revision] Resolving the bulkiness of fixed weights, this modular iteration integrates interchangeable high-density blocks (e.g., tungsten alloy) onto a pelvic carrier and track system for streamlined load distribution.

スクワットで腰が痛くなる人向け

・自分の場合、最大の悩みが腰へのダメージ、2位が膝へのダメージ

腰にやさしいスクワット用デバイス

For weightlifters and fitness enthusiasts who suffer from debilitating lower back strain during heavy squats, this device relocates the load path entirely away from the spine. By integrating high-density tungsten alloy cartridges into a pelvic distribution harness and utilizing a telescopic guide rail system, the barbell's massive downward force is safely bypassed and transferred directly to the pelvis. This effectively eliminates lumbar compression while maintaining pure leg and gluteal muscle activation.

[No.4] 花粉対策デバイス：Face-Surface Laminar Flow Shield [Rev.3] - Recirculating

見た目を気にしない人向け

・前回タイプはエアーが下方にいくほどバリア性能低下（No.3）

花粉対策デバイス（最終版）

To eradicate the lingering issue where air barrier performance degraded toward the bottom, the final iteration introduces a closed-loop recirculating architecture. By deploying a lower return air fan and peripheral suction inlets, the expelled air is continuously captured, filtered, and fed back into the system. While this achieves the ultimate, unyielding 360-degree atmospheric shield with zero reduction in lower-tier efficiency, it has unfortunately evolved into such an intimidating, heavy-duty apparatus that practical daily use feels further away than ever.

花粉対策デバイス（全周ガード）

　

While the previous aerodynamic cap successfully shielded the front, it left the wearer vulnerable to crosswinds and pollen approaching from the flanks or rear. Rev.2 introduces a true omnidirectional defense system by integrating peripheral slit outlets and flow-straightening honeycomb panels around the entire brim. This deploys a 360-degree multi-layer vertical air curtain, completely sealing the user in an impenetrable personal atmospheric dome from all angles.

スタイリッシュに花粉対策したい人向け

・キャップのつばでエアカーテン形成

・前回の首輪式（No.1）よりスタイリッシュかつ効果的

花粉対策デバイス（改良版）

Addressing the glaring aesthetic drawback of the previous neck-worn model—which unfortunately resembled a veterinary cone—this revised iteration seamlessly integrates the laminar flow system into a standard daily-use cap. By routing the air intake and HEPA filtration through the visor manifold, it establishes a vertical downward air curtain over the face. This aerodynamic refinement not only eliminates social awkwardness but significantly optimizes pollen deflection efficiency for urban commuters.

花粉対策デバイス

Every spring, humanity struggles against an invisible enemy: pollen. While AI and semiconductors advance at breakneck speeds, anti-pollen technology remains stubbornly primitive (relying on clumsy cloth masks). This device was conceptualized out of pure frustration, aiming to create an invisible, multi-layered air curtain around the face using a neck-worn laminar flow generator. Though it currently suffers from a slight design flaw—making the wearer look somewhat like a dog wearing a medical cone—it represents a bold step forward in personal atmospheric boundary defense.
