I'm very intrigued by this and I can see what you are going for. Let me sum it up. This is a wizard who can spontaneously cast all of his spells as a sorcerer can by channeling his trinkets. He still has a spell per day limit as any Mage should. His limit of spells known is only limited by the number of trinkets he can afford to craft. It's mostly a flavor thing, but it does have some advantages all it's own.
With that said, I've got some ideas to push this along. Instead of using a spell book or schematics book, why not just call them revelations or something along the line that he has discovered and he can imbue a new trinket each level of any level spell he knows. Instead of having spells per day, he can activate each of his trinkets a number of times per day, per trinket level. Use the sorcerer spell progression for this purpose.

Craft Trinket: Using the craft skill, the Mage can create small trinkets the house his arcane power. These trinkets cost three times as much as scrolls of the same level spell to craft.
Trinket Slot: A Trinket Mage may have a number of trinkets active at any time equal to his level. In addition to this, he can have an additional level 1 trinket for each intelligence bonus he has.
Trinket Surge: At fifth level and every five levels thereafter, the trinket Mage can use each of his trinkets an additional time per day.
Trinket Mastery: I'm really not sure how trinket mastery would work, but I tossed around the idea of allowing adding meta magic feats instead of extra uses per day, maybe if that method was used, two meta magic feats could be used at once. Meh.
There could be a lot of tweaking to this, but it's just an idea I had after reading toys.
