Watch Packaging with Hinged Hollow Holders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing watch packaging does not provide sufficient protection against impact due to the rigidity of the support and slide mechanism, which can cause damage if the sheath has roughness in the fracture area.
Innovation Solution
A protective packaging with a sheath and a support element featuring two hollow holding elements connected by flexible hinges, made from recyclable materials like cellulose or Paperfoam, providing additional protection through a rigid structure and adaptive features for different watch sizes and shapes, including height adjustment and locking mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid support and slide mechanism are used in watch packaging, then the structure provides stability and protection, but the rigidity can cause damage to the watch if the sheath has roughness in the fracture area
Solution Approach 1:
The patent changes the material parameters by using cellulose-based materials (Paperfoam, moulded cellulose) instead of traditional rigid plastics. These materials have different mechanical properties - they are less brittle and more compliant, allowing them to absorb impact energy without creating harmful rigid contact points that could damage the watch.
Solution Approach 2:
The support element is made from composite cellulose-based materials that combine the benefits of rigidity and compliance. The material structure allows it to provide protective function while being less harmful to the watch, effectively creating a composite solution that balances protection with safety.
2Strength
If traditional plastic packaging materials are used, then the packaging provides adequate protection, but the materials are more brittle and less environmentally friendly
Solution Approach 1:
The patent changes the material composition parameter by using cellulose-based materials (Paperfoam, moulded cellulose) which have different physical properties compared to traditional plastics. These materials are less brittle, more recyclable, and maintain adequate protective strength while being environmentally friendlier.
Solution Approach 2:
The packaging uses disposable cellulose-based materials that are designed to be biodegradable and recyclable. These materials provide adequate protection during use and can be easily disposed of or recycled afterward, eliminating the need for complex recycling processes and reducing environmental harm.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The packaging offers enhanced protection against impacts by combining the sheath and support element, preventing shear deformation and ensuring easy watch removal, while being lightweight and made from less brittle materials compared to traditional plastics.
Implementation Method 1
two hollow holding elements connected to each other by at least one hinge
Implementation Method 2
each side wall is corrugated in shape
