š Case Study
Automotive EV Battery Housing Modular Fixture System
Frequent model changeovers requiring new fixtures every 18 months; $420K average per dedicated fixture
šļø Project Overview
High-volume aluminum battery enclosure line (250,000 units/yr)
šÆ Challenge
Frequent model changeovers requiring new fixtures every 18 months; $420K average per dedicated fixture
š§ Design Approach
Standardized base plate + interchangeable locators/clamps using ISO 8573-2 pneumatic interface and M12 T-slot grid

AI-generated project design illustration
š Key Calculations
Changeover Time Reduction
Īt = t_old ā t_new
Result: 22 hrs ā 47 min
Enables same-day model switch
Modular ROI Payback
(Fixture Savings Ć Qty) / Annual Cost
Result: 14 months
Based on 7 fixture variants/year
T-Slot Load Capacity
F_max = Ļ_yield Ć A_net
Result: 18.6 kN per M12 fastener
Validated for 2.5Ć max clamping load
š Results
Fixture CAPEX reduced by 68%; engineering lead time cut from 12 ā 3 weeks; OEE increased from 71% ā 89%š” Lessons Learned
- ā¢Grid pitch must match largest common bolt pattern (M12@50mm works for 92% of EV parts)
- ā¢Pneumatic quick-connects require ISO Class 2 filtration
- ā¢Modular documentation must include version-controlled 3D PDF assembly instructions
