Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Optical systems, such as optical dimensioning systems, are susceptible to impact damage and vibratory forces, leading to inaccuracies in metric and dimension measurements.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If optical systems are mounted in a fixed housing structure, then structural stability is improved, but susceptibility to impact damage and vibratory forces increases
Solution Approach 1:
The patent applies beforehand cushioning by pre-installing elastic isolation grommets at mounting locations and positioning dampers within the housing structure before optical elements are installed. These damping components are prepared in advance to absorb and dissipate impact energies and vibratory forces before they can damage the optical systems, resolving the contradiction between structural stability and susceptibility to harmful mechanical factors.
Solution Approach 2:
The patent introduces intermediary damping components (elastic isolation grommets and dampers) between the housing structure and optical elements. These intermediaries serve as mediators that decouple the rigid connection, allowing the housing to maintain structural stability while the intermediaries absorb and isolate impact damages and vibratory forces from reaching the optical systems.
2Measurement precision
If optical elements are rigidly mounted to maintain calibration, then measurement accuracy is improved, but susceptibility to shock and deflection increases
Solution Approach 1:
The patent applies local quality by providing differential mounting characteristics: optical elements requiring high stability (like lasers) are mounted with rigid fixtures to measurement surfaces, while isolation grommets and dampers are strategically positioned at critical locations where shock and deflection risks are highest. This localized application of different mounting qualities allows measurement accuracy to be maintained where needed while protecting against harmful factors at vulnerable points.
Solution Approach 2:
The patent employs composite mounting structures combining rigid mounting components (for stability and calibration) with elastic isolation grommets and damping materials. This composite approach creates a hybrid mounting system where rigid elements maintain optical alignment and calibration for measurement accuracy, while elastic and damping components absorb shock and reduce deflection, resolving the contradiction between rigid mounting benefits and vulnerability to mechanical hazards.
3Object-affected harmful factors
If damping components are added to isolate optical systems, then protection from vibratory forces is improved, but device complexity increases
Solution Approach 1:
The patent applies this principle by using simple, inexpensive elastic isolation grommets and basic damper components that can be easily replaced if needed. These relatively simple damping components provide effective vibration isolation without requiring complex mechanisms, electronic controls, or precision adjustments, thereby protecting optical systems from vibratory forces while minimizing the increase in device complexity.
Solution Approach 2:
The patent utilizes parameter changes by selecting damping components with specific material properties (elasticity, damping coefficients) and geometric parameters (size, shape, mounting configuration) optimized for the expected vibration and impact conditions. By carefully selecting and tuning these parameters, effective vibration isolation is achieved using straightforward damping components rather than complex active control systems, thus protecting against vibratory forces while keeping device complexity low.
