In 805/830 vs 806 Red X, 因為在車型 805/830 和 車型 806對比后只有門板有差異 。 WOW BOB DOOR MOLDING RED X CANDIDATE Passed B vs C with 95% of confidence that the molding door panel is the Red X with plete separation and end count of 完全分離， End count 為 5的情況下， 以 95%的置信度通過 B v S 表明門板裝飾件是 Red X B vs C Six pack B = 有門飾件的 車 Vehicles with door molding.

In other words, find one characteristic in the same door panel 805/830 model that makes the difference, because there are some door panels that require almost 20 lbs to pulled out of it position from the door and there are others with less than 10 lbs to pulled out of it position。 The customer enthusiasm limit is 18 is enough to keep the door panel in position at low Red X 為門外板裝飾件 ， 我們決定改變策略 ， 從車型到車型變到卡車到卡車 ， 因為門外板裝飾件對 Cadillac車型來說是唯一的 。 換句話說 ， 同樣的門板裝在 805/830 車型上卻產(chǎn)生了差異 ， 原因是一些門板從門上拽出需要 20磅的力 ， 二另一些只需要小于 10磅的力 。 顧客的要求是 18磅 ， 這已經(jīng)足夠保證門板以較低的成本固定到相應(yīng)的位置 。 BOB WOW BIG CONTACT AREA SMALL CONTACT AREA 大間隙BIGGAP 小間隙SMALLGAP 門邊緣 DOOR FLANGE 門邊緣 DOOR FLANGE The main characteristic that cause difference between the door panels 805/830 model is the poor contact of the flange on the door due that there are panels that present some deformation on the top edge and cause the poor 805/830 車型門外板差異的主要特征飾門邊緣連接不良 ， 導致門板上邊緣變形 BOB vs WOW door panel最好、最壞門外板對比 DOOR FLANGE CURRENT USED DOOR FLANGE PROPOSED This picture shows that if we change the door flange mm lenght we guarantee that all door panels require almost 18 lbs to pull out it position because the contact area will be bigger against door flange current DOOR FLANGE CURRENT USED DOOR FLANGE PROPOSED 這張圖片表明如果我們把門邊緣加長 ， 我們確保開門力會增大 18磅，原因是接觸面積比當前增大了 。 當前使用的門邊緣 推存使用的門邊緣 B = Vehicles with new flange longer than mm. C = Vehicles with current flange smaller than mm. Req: confidence = 95% Passed B vs C with 95% of confidence that the new flange length mm is the Red X with plete separation and end count of 6.
