Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a sound-absorbing sheet is used to cover a large target object from below, then soundproofing is achieved, but the sheet sags downward due to gravity causing gaps and reduced heat dissipation

Engineering Contradiction:
Improvesoundproofing performanceVSAvoidheat dissipation performance
Core Design Contradiction:
Object-affected harmful factorsVSTemperature

Solution Approach 1:

The sound-absorbing sheet is designed as a flexible thin film structure that can conform to the target object surface. By using a reinforcing member with appropriate rigidity, the sheet maintains its position without excessive sagging, preventing gap formation while preserving sound absorption capabilities.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The sound-absorbing sheet is divided into multiple regions by the reinforcing member structure. The sheet is segmented into mounting parts that attach to the target object and a heat-dissipating region that remains exposed. This segmentation allows different portions to serve different functions: soundproofing near the object and heat dissipation at exposed areas.

Inventive Principle:
Principle #1Segmentation

2Temperature

If the sound-absorbing sheet is exposed to allow heat dissipation, then heat dissipation performance improves, but the sheet deforms due to gravity causing gaps

Engineering Contradiction:
Improveheat dissipation performanceVSAvoidsheet position stability
Core Design Contradiction:
TemperatureVSStability of the object's composition

Solution Approach 1:

The reinforcing member acts as a counterbalancing structure that compensates for the gravitational force acting on the sound-absorbing sheet. By positioning the reinforcing member on the heat-dissipating surface side, it provides structural support that prevents the sheet from sagging downward, maintaining stable positioning while allowing heat dissipation through exposed regions.

Inventive Principle:
Principle #8Anti-weight (Counterweight)

Solution Approach 2:

Different regions of the sound-absorbing sheet have different functional requirements. The mounting parts require strong adhesion and structural support, while the heat-dissipating region requires exposure to ambient air. The reinforcing member is strategically positioned to provide support where needed while leaving heat-dissipating areas exposed.

Inventive Principle:
Principle #3Local quality

3Stability of the object's composition

If a reinforcing member is added to prevent sagging, then sheet position stability improves, but device complexity increases

Engineering Contradiction:
Improvesheet position stabilityVSAvoidcover structure complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The reinforcing member serves multiple functions simultaneously: it provides structural support to prevent sheet sagging, acts as a mounting structure to attach the cover to the target object, and creates the geometric configuration that exposes heat-dissipating regions. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The reinforcing member and mounting structure are merged into a single integrated component. The pair of reinforcing members are positioned to both support the sound-absorbing sheet and provide mounting attachment points, combining structural support and fastening functions into one element, thus reducing overall structural complexity.

Inventive Principle:
Principle #5Merging (Combining)
