Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If conventional vinyl packaging is used, then the packaging provides basic protection, but it is difficult to clean and prone to contamination

Engineering Contradiction:

ImprovecontaminationVSAvoidcleanability

Core Design Contradiction:

Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The packaging material transitions from conventional vinyl to heat-shrinkable material, changing the physical state and properties of the material. This allows the packaging to be tightly fitted around the cable through heat application, creating a smooth, non-porous surface that is easy to clean and resistant to contamination, directly resolving the contradiction between protection and cleanability

Inventive Principle:

Principle #35Parameter changes

2Object-affected harmful factors

If conventional packaging is used, then the packaging provides basic coverage, but the volume is large causing cable tangling and physical interference

Engineering Contradiction:

Improvecable tanglingVSAvoidpackaging volume

Core Design Contradiction:

Object-affected harmful factorsVSVolume of stationary object

Solution Approach 1:

The packaging material undergoes phase transition from expanded state to contracted state through heat application. The heat-shrinkable material is applied in an expanded state for easy installation, then heated to cause it to shrink and conform tightly to the cable, reducing volume and eliminating cable tangling while maintaining protective function

Inventive Principle:

Principle #36Phase transitions

3Adaptability or versatility

If conventional packaging is used, then the packaging moves with cable movement, but it is not fixed and requires additional materials to adjust range

Engineering Contradiction:

Improvepackaging range adjustmentVSAvoidadditional materials required

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The packaging system transitions from a static, fixed structure to a dynamic, adjustable structure. The heat-shrinkable packaging can be heated to different temperatures to achieve different levels of shrinkage, allowing the packaging range to be dynamically adjusted to fit various cable configurations and environmental requirements without needing additional materials

Inventive Principle:

Principle #15Dynamics

4Volume of stationary object

If heat-shrinkable material is used, then packaging volume is reduced and contact with cable is improved, but heat application is required

Engineering Contradiction:

Improvepackaging volumeVSAvoidheat application

Core Design Contradiction:

Volume of stationary objectVSUse of energy by moving object

Solution Approach 1:

The patent replaces complex mechanical adjustment mechanisms with thermal processing. Instead of using mechanical devices to shrink or adjust the packaging, heat application is used to cause the heat-shrinkable material to contract and conform to the cable. This substitution of thermal energy for mechanical systems achieves volume reduction and improved contact while simplifying the overall system

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Disclosed herein is a cable packaging for medical devices that is provided with a perforated line and having heat shrinkage characteristic. With a capable packaging for medical devices to wrap around a cable that is configured to connect two or more apparatuses to each other, the cable packaging is formed of material that is shrunken by heat so as to come into close contact with the cable, and the cable packaging includes a perforated line so as to be separated from the cable. By forming the packaging using heat shrinkage material, a packaging volume is reduced, and by fixing the packaging so as to come into close contact with the cable, the durability of a connecting portion is improved. By forming a perforated line, the packaging is removed or maintained according to use of a user, and contaminated substance is easily cleaned
