Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Earth moving machine wear elements with integrated electronic devices face challenges due to extreme working conditions, leading to capsule deformation, particle compaction, and difficulty in extracting and recycling the electronic devices, which affects their integrity and recycling efficiency.
Innovation Solution
A protective capsule design with a removable cover and extraction means, such as threaded holes, that attenuates pressure forces and facilitates smooth extraction of the electronic device, minimizing deformation and recycling issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the capsule is made robust to protect the electronic device from pressure and deformation, then the protection capability is improved, but the capsule cannot be extracted from the wear element at the end of service life
Solution Approach 1:
The capsule is divided into two main segments: a robust container that remains in the wear element and provides protection, and a removable cover that can be extracted. This segmentation allows the protective function to be maintained while enabling access to the electronic device for recycling or replacement without extracting the entire capsule assembly.
Solution Approach 2:
The electronic device is extracted from the capsule container through the removable cover mechanism. This allows the valuable electronic components to be removed and recycled separately from the wear element, solving the extraction problem while maintaining the protective container in place throughout the wear element's service life.
2Reliability
If the capsule is fixed securely inside the wear element, then the reliability of electronic device protection is improved, but the difficulty of extracting and recycling the electronic device increases
Solution Approach 1:
The capsule system is segmented into a permanent container portion that remains fixed in the wear element for reliable protection, and a removable cover portion that facilitates extraction. This segmentation enables the container to provide continuous reliable protection while the cover allows efficient recycling of the electronic device at end of service life.
Solution Approach 2:
The design enables selective discarding of the wear element and recovery of the electronic device. The removable cover allows the electronic device to be extracted and recovered for recycling or reuse, while the container may remain in the wear element or be discarded with it, optimizing the recycling process.
3Stability of the object's composition
If particles are allowed to compact between the wear element and the capsule, then the attachment stability is improved, but the pressure deforms the capsule and hinders extraction
Solution Approach 1:
The capsule is segmented into a container and removable cover, where the container can withstand and distribute the compaction pressure from particles, while the cover can be removed to access the electronic device. This segmentation allows the container to maintain attachment stability through pressure while enabling eventual extraction despite deformation.
Solution Approach 2:
The container is designed with sufficient structural strength to cushion and absorb the compaction pressure from particles before it reaches the electronic device. This beforehand cushioning protects the device from deformation while allowing the container to remain in place, and the cover can still be removed for extraction despite any deformation that occurs.
