Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercial off-the-shelf (COTS) circuit boards lack adequate mounting points for highly kinematic environments, making them inadequate for applications requiring shock and vibration resistance.
Innovation Solution
The use of stabilization disks and a replacement ILM plate to create virtual mounting points on COTS circuit boards without fabricating additional holes, allowing for secure attachment to a chassis using adhesive and fasteners, thereby providing enhanced mounting solutions in kinematic environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If COTS circuit boards are manufactured with standard mounting points, then mounting ease is improved, but circuit board real estate is wasted and cost increases
Solution Approach 1:
The patent pre-positions adhesive receiving structures (recesses or protrusions) at multiple potential mounting locations during circuit board manufacturing. These structures are prepared in advance but only activated when needed, allowing flexible mounting point selection without permanently dedicating space to all possible locations. This preliminary preparation enables on-demand mounting point creation.
Solution Approach 2:
The patent introduces adhesive receiving structures as intermediary elements between the circuit board and mounting hardware. These structures serve as virtual mounting points that can be activated at any location by applying adhesive, eliminating the need for physical mounting holes at every potential location. The intermediary structure enables flexible mounting without consuming board real estate.
2Ease of manufacture
If COTS circuit boards are made without additional mounting holes, then manufacturing cost is reduced, but mounting versatility in kinematic environments deteriorates
Solution Approach 1:
The patent makes the adhesive receiving structures multi-functional by designing them to serve both as adhesive retention features and as mounting point activators. The same structure that retains adhesive during manufacturing also enables mounting point creation in the field, providing universal functionality that reduces manufacturing cost while maintaining mounting versatility for kinematic environments.
Solution Approach 2:
The patent changes the state of mounting points from fixed physical holes to activatable virtual points using adhesive. By changing the parameter of mounting point existence from permanent to conditional, the system achieves both low manufacturing cost (no holes drilled) and high mounting versatility (points created as needed at any location).
3Adaptability or versatility
If virtual mounting points are created using adhesive receiving structures, then mounting flexibility is improved, but device complexity increases
Solution Approach 1:
The patent merges the adhesive retention function and the mounting point activation function into a single integrated structure. The adhesive receiving structure simultaneously serves to hold adhesive during manufacturing and to enable mounting point creation in the field, reducing the number of separate components needed and simplifying the overall device complexity while maintaining mounting flexibility.

AI summary
A system is disclosed which utilizes a stabilization disk 30 or rigid cup containing adhesive which is bonded to an underside of a circuit board and then bolted to a chassis of a piece of military electronic equipment, so as to create a mounting location between the circuit board and the chassis where the circuit board is lacking a regular fastener receiving mounting hole therethrough.
