The core intention of replacing the hand model with anatomically inspired bone structures was to elevate the piece from a mere prop/toy to a refined item of wearable jewelry. While the new bone-like geometry represents a significant aesthetic improvement, two critical structural challenges remain:
- Aesthetic and Detail Refinement: Although the design is better, the individual bone components still appear slightly stiff and could benefit from further exquisite detailing
- Structural Integrity and Articulation: Crucially, the current structure lacks cohesion. The linked components feel like a collection of scattered parts rather than a single, articulated whole. The connections are functionally unstable; they are sliding and fail to maintain a defined position or fixed orientation.
Anti-Slip Solution and Critical Evaluation (防滑解决方案与批判性评估)
To address the issue of sliding and uncontrolled movement, I implemented an initial anti-slip solution using silicone gaskets (或：O-rings) strategically placed within the joint.
Evaluation of the Method:
- Positive Outcome: The method is functionally effective. The silicone elements successfully create the necessary friction and tension to prevent the components from sliding, achieving the desired fixed position and stability.
- Critical Problem: The major drawback is the aesthetic compromise. The exposed silicone plug is highly visually disruptive (或：obtrusive) and detracts significantly from the piece’s overall jewellery-grade finish.
Next Steps in Structural Design:
The challenge now shifts from functional failure to aesthetic integration. I must pursue a refined solution that maintains the anti-slip function while minimizing or completely eliminating its visibility. This requires exploring design modifications, such as:- Miniaturization: Significantly reducing the size of the silicone element to make it less prominent.
- Concealment: Re-engineering the joint mechanism to fully recess or internally hide the gasket/plug within the printed bone structure.
- Alternative Friction Systems: Investigating entirely different mechanical friction or locking methods.
