Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital X-ray detectors are heavy, thick, and rigid, making them less portable and more susceptible to damage from physical impact, which limits their versatility and durability.
Innovation Solution
A digital X-ray detector assembly featuring a support panel with a rear and front shock absorbing structure, a reflected light absorption layer, and a shell assembly that surrounds the detector assembly, providing both mechanical protection and ergonomic improvements through lightweight, composite materials and shock-absorbing designs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional construction with heavy protective structures is used, then reliability is improved, but weight increases
Solution Approach 1:
The patent applies beforehand cushioning by incorporating shock-absorbing structures (foam layers, compliant mounts) between the detector array and the shell assembly. These structures are pre-positioned to absorb impact energy before it reaches the fragile detector components, thereby protecting them without requiring heavy protective enclosures. This resolves the contradiction by providing reliable protection through lightweight cushioning materials rather than massive protective structures.
Solution Approach 2:
The patent employs composite materials by combining the detector array with shock-absorbing foam layers and compliant mounting structures. This creates a composite assembly where the fragile detector elements are integrated with energy-absorbing materials that protect them during impact. The composite structure provides both the necessary protection and weight reduction, resolving the contradiction between reliability and weight.
2Reliability
If rigid enclosure is used to protect components, then reliability is improved, but device thickness increases
Solution Approach 1:
The patent replaces rigid protective enclosures with flexible shock-absorbing structures. The compliant mounts and foam layers act as flexible protective elements that can deform during impact to absorb energy, thereby protecting the detector array without requiring thick rigid walls. This resolves the contradiction by providing protection through flexibility and compliance rather than rigid thickness.
Solution Approach 2:
The shock-absorbing structures are pre-positioned between the detector array and the shell assembly to cushion against impact before it reaches the components. This beforehand cushioning allows the use of thinner overall construction while maintaining protection, as the cushioning function is built into the layered structure rather than requiring additional thick protective barriers.
3Reliability
If heavy protective structures are added, then reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The patent uses flexible shock-absorbing structures that provide protection without the weight penalty of rigid protective enclosures. The compliant mounts and foam layers protect the detector array while keeping the overall device lightweight and easy to handle, thereby maintaining ease of operation while improving reliability.
Solution Approach 2:
By incorporating shock-absorbing structures that are already in place before use, the patent provides durability without adding operational complexity or weight. The beforehand cushioning is integrated into the device structure, allowing portable operation while protecting against impact during transport and use.
4Manufacturing precision
If rigid attachment of components is used, then manufacturing precision is improved, but reliability deteriorates
Solution Approach 1:
The patent transitions from static rigid attachment to dynamic compliant mounting. The shock-absorbing structures allow the detector array to move slightly relative to the shell assembly during impact, absorbing the shock energy. This dynamic approach maintains manufacturing precision during normal operation while improving reliability during impact events by allowing controlled movement rather than rigid constraint.
Solution Approach 2:
The patent creates a composite mounting system that combines rigid support structures for precision alignment with compliant shock-absorbing materials for impact protection. This composite approach allows the detector array to be precisely positioned during manufacturing while being protected from impact damage through the integrated compliant structures.
